awesome! Good job! 10 psi? passenger weight?? lol

 

Yea 10.5psi and a 165lbs passenger.
Heres some slips, I know the 60fts are horrible.

 

Nice runs Mark! If you get that sixty foot down closer to 1.80 you will be knocking off low 13's...

 

nice runs, and yes for every .100 u take off ur 60ft u will pick up double in the 1/4 mile

so for a 2.2 60' u went 14.3
at a 1.8 60' u would go 13.5


the launch is key on a turbo car i bet u if u dont change a thing on the car and just keep going to the track and get the launch down u will see some 13.3-13.5's @ 103-106mph

ur car is going to mph higher then mine due to the 3:23 gears u have swap them out for some 3:42' or 3:73s and the mph will either stay the same or drop a lil but the et's will get much faster


get them slicks mounted and lets see some full boost launches and low 13 sec et's

 

btw did u take the air filer off when u ran

 

Yea the air filter was off and the ex cut out was off. It was a fun car, but I have to get those slicks mounted and balanced by nextweekend. But also this track I went to suxed bad. Horrible track but it was the only one open today.

Car felt like a monster after the 1/8 mile. Id like to see what it could do also on a cooler day. It was 85 degrees out today. And you can hear the tires spin on that run. I love bracket racing but I also love to just go fast so at this point im not to concerned about how consistant it is, I just want to let it do whats it may be capible of(slicks will be on next time)

Thanks though all you guys that have helped me out durring this build as Id be lost without your advice and help!!!!

 

so for a first time out did it exceed ur expectations?

 

H#LL ya it did! I was in awwww when they handed me the timeslip and it said 14.37. I knew it was going fast when I passed that GT/A. Amazing the power to be had from a turbo. Truley amazing! I was exspecting a 15 or a high 14 at best but I will admit you guys said it would be fast and its only just begun with this little turbo 3.1! I cant imagin a launch under boost and slicks on the car. Im excited for a run like that forsure!!

 

a turbo by far is the best bang for the buck when it comes to cost per hp, the only thing that comes out above that is nitrous but nitrous eventually gets exspensive when u factor in the cost of refilling the bottle


look at it this way for a 900$ investment including the converter u have knocked off just about 3 seconds what the car would run n/a, and at about this point u havent even reached its potential. when u reach that potential u will have knocked off about 4 seconds off the n/a et without spending anymore money then u already have,as the tune and ur launch technige come together

 

where did you end up going, 42?

 

Great job!

Its truly inspiring to see what can happen, step by step on a stock V6 car when it goes from mild to wild!

 

Yea I went to 42. What a track that was. Freaking scary at the 1/8 mile bump and the shutdown area

Thanks for the compliments everyone.

Dave, Rob, it was the best investment Ive ever or ever could have put into the car. Thanks for the inspiration on the build!!

 

any mods on the gta u were running against?
do u have any datalogs from ur runs?

 

Mark, just so you know, you have a 12 second car. Box your stock LCA's, get stickier (and taller) tires, get an adjustable fuel pressure regulator so you can up your fuel pressure with those injectors, then turn up the boost to 15-psi. If you can hook with a decent sixty foot, I guarantee a 12 second pass...

 

yeah if youre going faster than 9's that track is a bad idea. iirc i ran faster at 42 then i did at normalk, by like .3. not sure if its elevation differences or Jack has a shorter track lol. that thing needs more boost!

 

Blazer...I think that 42 is slower from what my racing buddies say, mainly if you cant get traction like me. The altitude at Norwalk is 620ft IIRC. But Norwalk has me spoiled, everything from the track, to the stands, to the bathrooms..lol

Heres the slicks I have, there in ok shape at least should help me though the season. I got them for FREE so I can't complain. These tires are close to the same size thats on the car. The tread width is 8.5 inches or so since there ET street slicks. I need to get some rims at a J/Y tommorow as the ones there on are not for a chevy bolt pattern. I have all ford friends...oh well.

I do have a few datalogs dave. Ill post them in a few. My intake temps went so high though. It was 85 degrees yesterday and I was pushing 150 at the traps. Its hard to keep it cool when you drive it a hour to get to the track. My intake temp at the starting line was 100 degrees!!!!

And Rob I cant wait to get this car into the 13's and hopefully the 12s someday soon. Im hooked on boost for life now!!









So what do you guys think?? These slicks will work for a little while?? I wish I could afford new ones but thats just not the case this season.

 

i was launching in 4WD so my 60' times were pretty decent, like 1.7-.8s in a F250 diesel. traction wasnt an issue, norwalk is better when its not so damn busy lol. for a hillbilly like me 42 was perfect to blow off some steam on a friday night. can hardly believe its been 6 years since i raced lol.

those look like they were on a fox mustang, 4 luggers. should hook, you will prolly pull thru the brakes too.

 

You need to get out and race man, its so fun to blow off steam. Im use to norwalk. Man, i've been going there since I could walk and raced there since I was 16. I was amazed that I litterly could have gotten in 10+ runs at 42. But I didnt see a point as it was hot so I had to let the car cool down and I was burning off my street tires. But 42 is a decent spot to just go race here and there. Im just spoiled with the track that Norwalk has.

Yea they were those 4 lug conv. off a stang. I did the e-brake deal once at the track to get the turbo up to spool but went a 14.69 the worst of the day. And it was a 2.35 60ft time.... thats slow as crap.

 

i notice that the older i get the more cautious i am with racing my DDs, back in the day it was alot different. id be at 42 friday for some grudge racing and back out on sunday for bracket racing. my very first pass was at norwalk in my 2.8 dime and ran a 19 sec pass lol. 2 days later on my way to work the T5 exploded on the highway lol. once i get back from training id like to hit the track, but family dictates my schedule lol.

 

I totally understand man. This camaro was my DD up untill about a year ago. Thats when I started messing with it alot more. Although Ive always raced my camaro since the day I bought it I just never really beat the crap out of it and let it shift itself. I won alot of races with that car. So consistant!!! But its a different story when its a auto. I've blow out so many t5's in my old fox mustang. Always 3rd gear. I use to just go buy another one every month is seemed like it. And I wont even get into all the stock axles I twisted off when I was stupid and had slicks dumping it at the line at 4k rpms.I wish I had videos of that stuff.

 

haha yeah 3rd gear is touchy in mine, im babying it cuz it needs to get me to new mexico and back. i have the original sittin in the garage hopefully ill have some time to go thru it at the end of the summer and put some Astro gears in it. thats a big step, 5.OH to a 6 shooter. i know my mustang to blow the doors off my blazer right now and i have more money in the blazer lol.

 

shorter tires , he already has 3:23 rear gears so taller tires would make that even worse i wouldnt go any taller then a 26 inch tall tire on his car till he gets some 3:42's or 3:73's then id go with a 28 inch tall tire

 

The tires I just got are 26" ones. Dave what did you say your intake temps were with the volvo IC. 150 or so?? I think I need to get into a routine to ice that intake on the piping right before the Tb as its being a heat sink.

 

I got my mustang into the low 13's at one point but those cars are so light and it was stick. That motor has such a big aftermarket so I had quite a bit of bolt ons. Man that thing would run a 14.0 one time and a 13.3 the next. The most inconsistant car Ive ever owned. But personally I like the little six shooter more then that mustang!!

 

yeah they were up[ there , when i hook up my good computer ill go threw my logs and see what they were for sure

u could get 2 8 or 10 inch electric fans from ebay and mount them on the intercooler which will help

 

Yea those fans are a good idea. I wounder how hard it would be to make a ice box arround the intercooler. Ya know just fill it full of ice and water arround the IC. Or is that a dumb idea?

 

12's is a guarantee with a 1.8X 60-foot, just up the fuel pressure and watch your air temps...

Hellz no, I wouldn't go shorter, no way. The 700R4 has too large of a gear ratio spread between first gear and second, which equals too large of a RPM drop between gears (large torque drop). The 28" tire will help the transition from 1st to second tremendously, and it won't hurt his sixty foot at all...

 

or get an alky kit

 

Vortech has something similar for the Mustang crowds, they call it their "Igloo Mondo Cooler", but its positioned just above the intake manifold, not by the Intercooler (uses chilled water). Very expensive, but I hear it works incredibly. Don't see why you can't fabricate something similiar, go for it...

 

I cant afford it! Im in for some home made ideas though.
Isnt a alky kit like 300 bucks?

Rob I got the 26's they should be fien right?? I hope so. As there all Ive got for a bit till I save up some cash for new ones.

 

+1

 

I was thinking making up a sealed box arround the whole intercooler, and having it so I could literly dump in ice and water in it. There wouldnt be flow though unless I rigged up some type of pump to move the water arround??

 

just did a quick search on fleabay

http://www.ebay.com/itm/WATER-INJECT...sories&vxp=mtr



and you can use your windshield washer tank lol

 

They will be fine, and will help you hook big time...

By the way, where were your RPM's when you reached the finish line with that pass...?

 

5000Rpms on the dot at the finish line.

Does that alky stuff really work that well?? As I dont know crap about it.

 

when i was racing the F250 i put a snow alky kit on there and dropped 4 tenths and that was a 7000lb truck lol. your intake temps will drop, can run more boost and timing too. just dont run out during a pass lol. its easy and safe horsepower.

 

Get it dynoed, then I'll tell you what rear tire you wanna run with those 3.23's...

Ohhhhh yeahhhh...

http://www.alkycontrol.com/

 

the alky is interesting, although how do I know what amount(jets) to use, and what can I use as fluid??? I know they make stuff just for it or use window stuff?? It interesting though. Amazing that you can shoot water into the engine and it actually helps it? I need to read up on all of that stuff.

 

5gph nozzle

and a taller tire will make the rpm drop from 1st to 2nd gear worse

 

We normally determine methanol jetting as we make our passes, similar to carb jetting (trial & error)...

Here is an excellent read...

http://www.importtuner.com/tech/impp...n/viewall.html

 

Just read through that link above... very interesting! I really like the idea of meth injec. That will definitly be my next larger purchase when I can afford it. Im just scared of those high intake temps. 140-150 scares me alot. Also Im going to boost check the pressure in a day or two. I want to make sure something isnt leaking.

You guys have a general rule for how long the boost should hold? I was going to start the test from the pipe coming off the turbo. And pump it to say 15psi and see how many leaks I have?? I basically made a pvc pipe that will slip in the pipe coupler and it has a valve stem on the other end. I know its rigged but its sealed tight and "should" work..

 

boost should hold till u let the presure out , when testing the pipes make sure neither end cap is pointed at you.ive seen firsthand what happenes when a cap pops out of the coupler with a few psi in the tube. think massive potato cannon !!!!!!!!!


u can piece together a meth kit for about 160 bucks if u buy the pump nozzle lines etc seperatly

u can buy a snow pump on ebay for 120 bucks, the nozzle is 5 bucks, 10 bucks for a boost switch, 3 bucks for a relay , alls thats left is a few bcks in hose and fittings


at ur power levels just buy a 5 and 10 gph nozzle, u will need the 10 when u step up the boost a good bit, and dont run a water/meth mix, run striaght methanol should be about 2 to 2 anda half bucks a gallon at the track.

in a pinch on the tsreet u can run blue windshield washer fluid

 

thats exactly what i used, simple and easy. not the best but i made sure there was plenty of ice cubes in there to keep it cool lol. some pumps have adjustable pressure so if you install the larger nozzle you can tune it by adjusting the pressure in the pump.

 

Well I got these steel rims for free also. So I got them mounted and such. I need to repaint them, but for being poor right now at least I have slicks on the car.

I added 15psi to them just to see if they wobble much and leave a nice black patch. They seem to be ok, but ill need to dial it in at the track and see what they really need for pressure. I just had to see if they would hook on the road, since they are DOT ones. Yes they hooked good. 2500rpm on the road and not a slip out of them. I cant wait to go to the track, dial them in, and make a good clean pass.

 

Heres the the rims and slicks cleaned up. And marked so I can keep a eye on that tire/rim spin just in case. They look ok I think for a cheep(as in me) racer budget at the moment??? If I ever make in into the 12's I need tubes, screw/bead lock, and all metal valve stems. The NHRA track im at has tough rules. But its for safety. But honestly if I get into the mid 13s ever Id lock the rims anyways.





You think my sig ###'s are close. I need to get on a dyno in the next few weeks when I get that tune down pat.

 

u wont need tubes or screws, i never ran tubes in mine my first set was screwed but when i went to a larger tire i left the screws out.

a turbo v6 3rdgen wont leave hard enough to spin the rim inside the tire ,well maybe with a 5 speed and 4k rpm launch

 

Who knows the best way to calc, the ft/min of air for plotting the comp map. I know how to read the thing and map it but im not sure the way im calculating lbs/min is the right way. I want to see if I raise boost if the turbo is more or less effiecent.

I just using a map for a to4e model with the same trim as mine. Thanks for any help!

 

well you need to calculate your pressure ratio using variables such as, engine airflow in CFM(CID*est VE), elevation, projected boost pressure, humidity, etc. then you need to calculate the total projected airflow(depending on boost). there should be plenty of documentation on the web, do a google search and you should find exactly what you need.

there may be an output in your datastream that plots the airflow in gms/sec, should help compare your calculations too.

HTH

 

u are currently making about 250-265 hp so u are in the 25-27# per min range for airflow



add more boost

 

Yea no kidding looking at that map it looks like in really coul add and be efficent. Those are close the figures I was coming up with. 32lbs/min at 6k rpms. 14psi looks like a good trial to tune and see what happends. The most Ive ever went was 12.5psi so far and I didnt do that much because that was before I got the new fuel pump

As I add boost the cfm or lbs/min goes up doesnt it because of the added hp?
