Ok got to drive the car on a 50mile round trip. Ran fine, just a little richer then i'd like at crusing. It was hovering at 14.5 AFR average. Before I touch that does the warmer weather make the car run leaner or richer?? Its like 60* out today. And I though that the warmer it is the richer the car is since the air isnt so dense.

Anyways, I added a log of a WOT pull only for 0-85Mph or so. It shifts much better now that the fuel cut of is set right...opps, on my part. But I turned the WG duty cycle down and dont like it, takes to long to spool up. Im just starting to relize that im going to get a little boost spike if I want it to spool up fast but in general the car is running smooth, starts well when hot/or cold. And the Tcc locks up good when crusing and isnt locked when 40%tps and higher at certaint mph.

Let me know if that log looks ok, as I think it does?? 0-80Mph in 11 seconds?? Not bad right with a crappy start and a slow spool up...And WOW does the intake temp go up fast under boost on a warm day after crusing, absolutly no knock though

Row 19-97 is the 0-80mph area in 11.36 seconds.... Keep in mind the low boost level, and the slow spool up. I think thats respectiful considering. I drove about 1 1/2 hours on this tune so its was supper conservitive since I cant just pull over and fix it..LOL And had a 200lbs passenger.. Some one had to watch the laptop.

 

thats not to bad liek i said with the under k style its going to be harder to make really big numbers.

but in about 2-3 weeks i should be a site sponsor here, once i get that ill hook u up with a deal on a set of real turbo headers for that thing

 

yeah count me in for turbo headers, and for pricing info lol

/hijack

 

Let me know asap dave, as I really wants some.

Heres another log for your entertainment If ya wana take a peak, I just put the good info on there. WOT only. Row 25-133 is the WOT 0-100Mph, still with the slow spool up becasue of the WG duty cycle.

 

unfortunatly i do not belive they will fit the s10 truck or blazer, my niebor has one that he might let me use to test fit a set on though since it has a blown motor in it currently

 

ill take a look, right now im working with some parts vendors and working on getting a nice product lineup besides what i will be making and selling once everything falls into place for me ill be pulling the trigger in the sponsorship

one of my planned products for u v6 guys is going to be a direct port nitrous system

 

Cool, dave. Thanks again.

On the latest WOT run to 100mph i got these numbers. After the latest run I think im ready for the track in a few weeks to really get into tuning WOT. But it seems to be good enough for now, and driving arround town

Heres some math from that last 0-100Mph log i attatched in the other post...Anyone know how accurate tunerpro is at the timing in its logs??? Anyways I posted those numbers on that drag racing forum, so theyll probly laugh at me for modding the V6 like I did and only be as fast as a stock z-28..

0-80Mph 10.62 Sec.
0-90Mph 12.49 Sec.
0-95Mph 14.25 Sec.
0-100Mph 15.71 Sec.

All I did was launch a little better considering the un-preped road and it said I cut 0.74 second off the 0-80Mph time from the log before. Thats why I wanted to know if anyone knows how accutate the timing is on tunerpro. Im not too concerned about how close it is to real time....Im just concerned that if it says im a seconds faster in this MPH to this MPH, if its actually somewhat accutate.

You guys think that those times are ok for what ive done?? Ive driving it so much that I cant even tell its that fast anymore...


SOB!!!!!!!!!!!!!!! I just now saw that my vac line from the silenoid controler was ate up from the dam* pully just enough that it wasnt air tight anymore. Explains why I kept messing with the command boost, and WG duty cycle and saw minimal results. Oh well thats what those 50-60 mile cruses are for...to fine the flaws in the system i guess!

 

the s10's have a bit more room in the engine bay and moreso with mine since i trimmed my inner wheel wells back for better clearance/access. only issue i currently see is the alternator location, mine is clocked out to clear the valve cover T bolts i installed, so it would be right in the desired spot for the turbo. but i was looking at it yesterday and i could relocate the alt to where the smog pump is and move the tensioner. the turbo would be placed where the alt is now. if anything i was going to build a hooker style wye pipe like what was available for the turbo buicks years ago. it wouldnt spool as fast but its simple. and the hedman long tubes thats on there now are more like mid lengths and are very similar to the hooker super comps i had on my t type. sorry eddi for the hijack

 

Ahh its ok 34blazer on th hi-jack...

Im really interested in those turbo headers also. Aren't you running $59 on that truck?? Else then the little benifits of crusing in closed loop, its fine if I just always run my car in open loop for now isnt it? I wouldnt see why it wouldnt be since im still new at the $59 and theres ALOT of stuff in there
for closed loop.. And I finally the tune is good enough to drive on the hi-way for a bit and even take it down the track...

@34blazer....70* today man!! In ohio!! Anazing isnt it??

@dave(project89)..What were you Intake Temps when you ran the 1/4 mile. Im seeing like a 81* temp at the begining of the run and it goes up to 127* at the end of the run. Then once off boost it goes down fast.
Is that normal for a intercooler like the one I have?????

This was on a 14.9@98MPH logg on the Gtech with 20 MPH head winds...LOL Windy as He*l out but its warm. Also 6.3 0-60Mph and 189RWHP as of g-tech. That g-tech is probly so far off but oh well it keeps me happy..... so 189*20% drivetrain loss=227hp. So even if im getting 210-240Hp im happy for now....Still@ 10psi of boost.

It was about 65 degrees out ambient temp when i did that..... Im starting to think of how to mod up something that will let the air flow into the IC better, that airdam sorta suxs...

 

Dont laught BUT..
Doubt anyone will believe me since I have no video of it, BUT, i did manage to stay side my side a 5gen V6 camaro today from 40mph up to 80mph. I didnt want a speeding ticket so i stoped the race... but still dont those new LLT 3.6L V6's have like 250-300Hp??
But anyways the car is a blast to drive as it was 70* today and I could just roll the windows down and cruse. Thanks everyone for the help thus far!!!! This car is just so fun to drive when on the hi-way. Its a sleeper till that turbo spools up. Fun Fun Stuff!!



The car ran a litter richer but only could you tell on the excel log. Average 11.8 under boost. (Crusing was 15.2 AFR average without boost) So I racked up 150 miles in the last two days with it being a pretty reliable car in town, crusing, and getting on it. So thats all I can drive it for a bit as the 93 is killing me at the pump when I get gas. Might get 30Mpg on the hi-way, but only like 3Mpg when on boost!! When its 4bucks a gallon...It gets exspensive!!

But to the bottom line...THANK YOU ALL FOR YOUR HELP THUS FAR!!! YOU KNOW WHO YOU ALL ARE!!!

 

nice, just for ***** and giggles pull the airfilter and then try another wot run again.
i bet that air filter is slowing u down.

my air temps would get into the 150-160* range so ur still fine

3mpg under boost is horrible u have to be way rish or somthing do u have decel fuel cut enabled?

what muffler do u have on the car as well ?might be time to put a cutout in the ex system u should be faster then what u are now @ 10 psi

 

Yea i do notice a littler difference with the air filter off(not much but it is there), and im thinking of routing the air filter out of the engine area as my intake temp hovers at 80-85* today when its only 70* out. The under hood temps are adding to my intake temps.. Intake temps never got above 132* though and thats with crusing then WOT. And once i let off the boost it goes down to normal really really fast. When i just went out and did a standing 1/4 mile it didnt go that high... 125 or so degrees at the top end.

Im just guessing the MPG at WOT, i have no idea what it is, but im sure its bad

I have just a magnaflow muffler on it, no cat. I want to get a cut out before I first hit the track forsure!!

 

i think the high in vegas today was 60ish. of course when i leave ohio the weather breaks lol. must be a black cloud following me around. im not using $59 in the blazer yet. im running $42 but i cant wait to swap to a 7730 because $42 sucks compared to $8D S_AUJP. im unpacking all my household goods right now, lots of spare parts lol. hopefully back on the project soon.

good to see yours is coming along nicely

 

Your IC is grossly inefficient, if you're getting intake temps that high, without heat soaking the IC from sitting still, or your turbo way out of its efficiency range.

When it's 80* or so out, I will see intake temps around 100 to 110* while cruising, then hit the throttle and within about half a second my intake temps drop to a degree or two above ambient. It's even better when ambient temps are 70* or lower.

Moving my air filter out of the engine bay did help, but not a great deal, maybe about 10* lower while cruising, next to no difference when in boost. I had to move my filter back into the engine bay, due to a newer radiator that I installed, that interfered with the intake tubing I had.

 

How do I find a comp, map on this turbo?? Its a ebay knock off...
TO4E t3/t4....

I do NOT like the way that I have that IC mounted right now, I think that if i rotate the fins of the IC twards the ground alot more airflow would be getting to it. I never did like the way the camaros breathed in air from below the car...

See in this pic how the IC in vertical..you think if I go through the trouble of making it horrizintal that it would help..... This pic is before i really mounted it but do you see what i mean by laying it horizintally??



What do you think?? Would this help?? Changing the position?

 

I think you should start by adding an air dam under the rad support, like is supposed to be there.

You may have to go as far as adding ducting eventually, but try the air dam first, it will make more difference than you think.

 

The airdam is there, this is just a picture from when I first mounted it and the turbo set up wasnt complete yet.

 

you may need to move the air dam forward to blow more air through the IC instead of up into the bottom of it. you may want to go so far as to build a deflector on the top side of the IC. This way, you blow air up from the air dam (mounted to the front bottom edge of the IC) up, hit the deflector and go through the IC. Just blowing air up in front of it may not be enough if its not directed through it. ...just my thoughts

 

Def. a good idea. Thats probley what im going to have to do. It got cold out again today(40*) out so I have to wait till it gets warm again to try different approaches out.

Does this sounds like crap??? Its with the exhaust open, about 4Ft from the turbo itself. You can actually sorta hear the turbo wining a little. Thats a first from it wineing by just reving it up??
http://www.youtube.com/watch?v=4TI_i...ature=youtu.be

Heres it with the exhaust like that driving down the road and back.... I had the windows up so the exhaust is louder, but when boost is being made it not as loud??
http://www.youtube.com/watch?v=4TI_iobC4z8

What do you think?? Will it help stricktly at the racetrack????

 

i told u the cutout would make a world of difference, the muffler u have is restricting the hell out of that thing.also with a turbo car the bigger the downpipe the better, there is no such thing as to big when it comes to the downpipe though u willk get to a point with minimal returns

and yes with a turbo car with an open downpipe the faster u go the quieter it gets.
i also bet u when u cut the pipe ur afrs changed

heres another test for u put the pipe back on then disconect it at the miffler and see if it runs the same as witht he pipe disconected in the front. if it does u know the muffler is the issue and replace it with a cheap 30$ bullet mufler

 

Yea huge difference in spool up time and power in general. I might just have to pick up a cherry bomb style muffer, to help me when im just driving an playing arround. But ill see if the muffler is the problem first, im sure it is, after where i had the exhaust open its just straight back 2 1/2 pipe all the way.

Oh yea AFRs did change, exspecialy at idle, but they were a little higher overall(about .2-.4)

 

if u buy a cherry bomb paint it black or something, a big red tube muffler under the back of the car will get u pulled over lol

summit ells cheap bullet mufflers that will quiet the car down a bit better then a cherry bomb and are still straight threw muflers

 

like one of these
http://www.ebay.com/itm/Dynomax-Race...cc36be&vxp=mtr

 

Ahh ok, I know what im looking for then. I dont know if ill get that by the first race but I plan to have the car running open like that at the track. Is it ok to have the cut out about 3-4 ft from the turbo??? After the 90* off the turbo, then the straight pipe down, then the last 90* to aim back to the back of the car... after that mess, I had the exhaust open(its about 3-4 ft in total off the turbo and about 2Ft from the o2 sensor)

 

yeah that will be fine

 

i almost forgot go datalog a 0-100mph run witht he pipe disconected so i can see the difference in the data log

 

Ill get on it on tommrow and make a run. Will that effect my tune alot? I think I have dialed in well. Im running a little more timing now and it seems to pull more at high rpms with no knock. Roughly 19* of timing at Higher Rpms, 10psi of boost.

 

the afrs may change a lil bit now that the ex isnt choked

 

Yea, they go up hu?? Just a little

 

they can go up or down a lil bit shouldnt be much though

 

I am so freaking jealous right now

and effe the noise police too, i got a ticket in strongsville for my exhaust and its not even all that loud lol.

 

On that blazer? Well thankfully I live in the country or id have tickets too. So they still do that emmisions crap out there?? I lived in akron about 8 years ago and they still had that stuff then....

 

no and thank gawd because im bleeding from the ears when i get out of that thing lol. i got the ticket in the mustang, 130 bucks out here they do the full visual inspection for smog gear and then idle, free rev at 2200 rpms. last time i had my fleet smogged was in crackron, forgot the exit but its right off I-77/76. by the time i got the blazer on the road it was exempt so i took the stock exhaust off. now the mustang is exempt(25+ years old). since im mil and stationed out of state im exempt anyway.

old jaloppys FTW!

 

Man, you just made my night....i havent heard it(akron) called crackron since I lived there Thats freaking awsome man!

 

oh yeah, some other car geeks and i would cruise all around there and pit stop at swensons in montrose for a half pounder and a california lol. way back when i had my buick. crackron....lol

/reminiscing

 

I found that with in my Jimmy (turbo Hybrid 3.2L 660), that it was actually quieter without a muffler, than with one. So I ran a 2.5" exhaust. I did have a catalytic converter in it though, from Magnaflow.

 

Hey dave, could you toss up a timing table that your were useing on that turbo set up you had. If you still have one?? I just wana see what you had for a timing curve.

Also you guys when on tuner pro my (spark advance to ref. pause is about 13 degrees???) Is that suppose to be my base timing, because on my timing light I set the base to 10 degrees and the ref. angle on the $59 is 9.84 degrees?? So what exactly is the spark advance to ref. pulse?? What im thinking is that is what the ecm is adding to the base timing, but i want to make sure Im thinking right... Thanks!

 

get urself an 89 2.8 maf bin and take a look at that. i basically ran a stock 2.8 table +4*

 

Ok ill check it and see. Just off the top of your head did your timing curve peak at mid rpms or high rpms??

 

i was somewere around 26* @ 7,000 rpms @ 9 psi timing peaked in the upper rpms but dont forget i also spun my motor just a tad over 2,000 rpms more then u do

ill dig threw my old tune files later, i dont know how well u can copy over a maf spark table since its not refernced by map presure.


the only way i see u could convert the table would be to convert the table to pounds per min of air then plot it on the compressor map for the gt3076 turbo and figure out how many pounds of air per minute = whats boost presure


unless i can dig up one of my old ignition maps then u can just copy that over since ms uses speed density

 

Holy crap man...26 degrees of timing @ 7k Rpms??

Ok @ my 10Psi I have all 17* and 18* degrees in my cells with a one 19* degree cell in the middle(3k area)

Man you didnt have knock with that much timing?? Mabey thats why I feel less power up on the top Rpms?? And in the next cells over 6-8 PSI ive got starting at 17 degrees up to 20 degrees but the curve is in the middle Rpms. Man Im thinking I need to work on these SA tables more.

I really didnt want to copy them, but get a basis of what the timing curve looks like..does it peak at the highest running RPM's of peak at the middle ones(3-5K)?

 

Im not sure how well you can see this but heres my map of the SA.

 

they peaked around 5,000 and cariied all the way out

basically i put all of my timing in by about 5k and just carried the table out


no knock that i ever knew about but i didnt have a knock sensor i just used my ears and checked my plugs from time to time

 

Lmfao used your ears for the knock..I would but I sure dont trust my tune one bit I check my plugs alot when Im really beating on it, to get a reality check. Plugs dont lie!

What kind of intaketemps were you seeing...did you have the volvo intercooler. Man, my timing is way lower then that...like ALOT. about 8-10*s lower.

 

mine got hot cause of the crappy volvo intercooler intake temps would get well into 140's i dont worry about it to much since i know of cars with blowers that see well into the 200's

 

Wow man 200* intake temps. Ive seen the highest of 132 so far@11psi, and that was after a long as* cruse then doing a standing 1/4 mile(2 times)opps. And really I need to get that airdam to work better. Dumb thing is sorta bent back from all the abuse over the years. I know thats not helping!

Well the weather looks like its gonna be nice on my day off so Ill get to play again on the timing, im going to add some timing and make that curve higher, then add fuel as needed..well see what happens I guess.

 

Well dave, I bumped the timing up and its maxing at 22* @10Psi 5krpms and out. Car didnt show any knock, and arfs are fine, but it was also cool out this morning. I was definitly cheating myself on timing. I looked at my stock spark map and it was 23 degrees at 100kpa 5600Rpms, so I sorta modded those numbers.

One problem I AM having is when it shifts into 2nd gear it spins "a" tire.

Every time when at WOT, so the boost goes down one psi or so for that split second the tires spin. I know that wont be a issue at the track but jeez the road was dry as a bone and still it spins at 30Mph??

I left like a 15ft burnout that i could see in the rear view mirror, the first time I went WOT. Its hard to tune WOT on the road when every time its shifts from 1st to second, it lights a tire up.

 

does it pull better with more timing?
the reason i told u the danger zone was around 21/22* was i didnt want u to jump right up that high until u got a feel for the tunning


do u still have the muffler unhooked?

weres the new 0-100 video and datalog?

 

Yea dave it pulls better forsure! I got it at the 22* area at 10psi and untill it gets up arround 70 degrees outside, im going to leave the timing there for now.

 

Tommorow Ill have one up, I only was going WOT up to about 60 or so today... I was just tuning the Afrs to match the timing, and ran out of free time this morning, ill post up a few rows and you can see where i spun the tires shifting into 2nd.. Layed like a 15 ft mark on the road at 35mph... the muffler is hooked up. I only had about 1 hour today to play with the car......

EDIT!:Heres the attatchemnts if you look at the mph at the 30ish MPH you can see that it doesnt move or i actually slowed down, a slight KR in there at a few spots that need attention.
