re: Fasteddis Turbo 3.1/3100 Hybrid
 

Weird with the nAst1 spark-cut 2-step I can build 9 psi at 2000 rpm.

re: Fasteddis Turbo 3.1/3100 Hybrid
 

yeah same on pilsburys car with the megasquirt


just for the hell of it i tried it on the iroc at 1,500 and it builds boost in a hurry , only bad thing is if i try to launch that low the car bogs big time

problem with fasts setup is he is trying to use an msd box as an antilag
by itself its only going to build a max of 5/6 psi with some tweaking of the fuel and ignition maps it will be able to build whatever his wastegate is set at

re: Fasteddis Turbo 3.1/3100 Hybrid
 

Ill just have to play with it. Now that I really think about it, that 25 plus degrees of timing and when I have low boost very lean in the map, isn't helping the anti lag at all. Ill play with it this weekend again and hopefully get it to where I want it. Even at the 4 psi at 2700rpms, the car really janks ya. That's what makes me want to see what the limit is that I can hold it at the line.

re: Fasteddis Turbo 3.1/3100 Hybrid
 

I do have a question. I noticed that when lagging the 4psi the intake temps really didn't go up when I overrided the alky. But if I get it to say, 8 psi should I arm the alky or override it? Will the temps fly up without the alky like it would I wasent on the 2step, and would the alky make the anti lag work better? This is a time where I wish I would have installed a 2 nozzle set up.

re: Fasteddis Turbo 3.1/3100 Hybrid
 

dont use the alky on the 2 step and see what happens , theres no load on the engine during antilag/2step so it wont detonate

on the other hand using the alky could give u the extra fuel u need but ive never used an antilag system with alky injection so i couldnt tell ya


ya know worst comes to worse use it as setup with no ignition retard , and add a 35 nitrous shot , use the retard to pull 1-2* while on the nitrous shot lmao

though if u did that im willing to bet u would get booted for no roll bar

re: Fasteddis Turbo 3.1/3100 Hybrid
 

Thing is though it's not adding any extra fuel; it just gets the normal WOT fueling and spark cut with mine.

re: Fasteddis Turbo 3.1/3100 Hybrid
 

is urs lighting off the mixture in the headers?

how many sparks does ur spark cut drop per 720* ?

i think the msd is only doing 2 per 720* , on my iroc i have the megasquirt set to 5 cuts out of 8 per 720*, and on the v6 engines i use 4 out of 6 per 720*

re: Fasteddis Turbo 3.1/3100 Hybrid
 

You'd have to ask Robert to know for sure, but the way I understand it it works like a normal rev-limiter, except instead of cutting fuel, it cuts spark instead. So it basically just cuts spark when the engine revs to the set rev limit and re-enables spark when it drops to the lower rev limit threshold.

Seems to do the job very well though. Can really see the flames shooting out the screamer pipes at night :D.

re: Fasteddis Turbo 3.1/3100 Hybrid
 

i'll clarify what i can:

caffeine has it right, it cuts as much as necessary, and only as much as necessary to keep it within its window of operation. if that means dropping 12 spark events in a row, coming back online for 3 events and then cutting again, that's how it will work. conversely, if only 1 event needs dropped out of 632, that will work too... the logic runs at 80Hz, so every 12.5mS the limits are checked against to see if a cut is needed or not.

for reference(on a V6):

12.5mS = 4800RPM.

up to 3200, spark events in multiples of 1(on and off). between 3200 and 4800, spark events will happen in multiples of 2. 4800-6400, multiples of 3. 6400-8000, multiples of 4.

re: Fasteddis Turbo 3.1/3100 Hybrid
 

ok so yeah its cutting out a bunch of cyls in a row , thats why it works as good as the megasquirt launch control. i should contact msd , and see how the box opeartes in 2 step mode. im pretty sure its 2 cuts out of 6 events on a v6

fast could prolly switch the box to 8 cyl mosde and figure out the difference he would have to set the rpms dials to to get more spark cut every 720*

re: Fasteddis Turbo 3.1/3100 Hybrid
 

Here'd she be launching with those big tires. I left 14psi in them. I would have went more to get a little squeak off the start but didn't have time to play with the psi in the tires.

I hope to mess with the Camaro Friday for a few minuets after work. Im learning a little as the post above had my head aching. But gotta remember im still a tad new at all of this. Im going to attempt to get it to ride up higher on the boost either by dumping off the spark some more hopefully. Ill take a vid and show yas if I get it to work right for me. Im going to run that 2 step next time I race it. 2 weeks from this weekend.

re: Fasteddis Turbo 3.1/3100 Hybrid
 

you need to go on open nights where you can go all out, I wanna see some all or nothing fastest time wins slips.........

re: Fasteddis Turbo 3.1/3100 Hybrid
 

That's what im going to do. In 2 Fridays. Id go to Milan but it cost too much and is just a horrid track compared to Norwalk...lol

re: Fasteddis Turbo 3.1/3100 Hybrid
 

Going to play with the 2 step on Saturday. Im looking forward to that!! Im going to attempt to just dump some timing in certain cells and also use the retard on the msd and see if I can get a tad more boost. Im hoping I can hold about 5-6psi at 2600-2800 rpms at the line but ill have to play with it and see.

On another note. My friend just got me 2 turbos for free. Told me they were tiny. Probly t25s but if they are junk im thinking of adding one to the lawnmower just to have something funny to look at while mowing the grass...lmao

re: Fasteddis Turbo 3.1/3100 Hybrid
 

Find out what they are, I might be interested in housings and/or wheels.

re: Fasteddis Turbo 3.1/3100 Hybrid
 

if u end up with one on the lawnmower one of the mr gasket micro diesel fuel pumps work great for pumping oil threw the chra

even a t25 would be to large for most push mowers , now if u have liek a 10-20hp riding mower it may work

but honestly u would be better off just buying a gallon of nitro fuel from the hobby store and putting that in the tank.

and yes lawnmower engines will run on nitro

re: Fasteddis Turbo 3.1/3100 Hybrid
 

It would be for more laughs then anything. I have a 18hp rider I though of tossing one on..lol

Ill get them on Saturday so ill let ya know six what they are but Im betting t25s off a talon. Just like I had when I first thought about turboing my Camaro.

Dave id toss nitro though it but I don't wana eat her up. I would think shed be eating oil after a instance like that...lol

re: Fasteddis Turbo 3.1/3100 Hybrid
 

i think a T25 would be too small for even a ~50HP lawnmower....

as small as a T25 is, it still moves a lot more air(and needs a lot more exhaust flow) than what a lawnmower engine could pull. i'm not sure it would ever spool.

re: Fasteddis Turbo 3.1/3100 Hybrid
 

Well its more of the site of the thing then to actually make boost. Its just a thing that ppl would get a good laugh of.

re: Fasteddis Turbo 3.1/3100 Hybrid
 

in that case.... if you removed the turbine and compressor wheels(and plugged the hole on the compressor side to prevent some kind of EGR going on), you would basically have a very strange muffler that also slowly heats the intake air. could run fake oil lines to it too, if you really wanted to.

re: Fasteddis Turbo 3.1/3100 Hybrid
 

Got to mess with the car just for a minuet after driving it 1hr back home. Heres a vid. I took some timing out just in cells at 2400-2800 rpms up to 5psi to see if it would help. It builds a good 3.7-4psi. This is at a 2500 rpm cut out. and about 7* of btdc timing. I didn't burn but 2 chips so I know it needs more work. This is in park though and IIRC it works better when its in gear and the brake is on but I didn't have time to toss on the slicks and try it out. My street tires wont work well I can tell you that no matter how good my brakes are.

http://www.youtube.com/watch?v=pBzpL...ature=youtu.be

re: Fasteddis Turbo 3.1/3100 Hybrid
 

its building pretty fast, but u need to test in gear not park, with load on the engine thr results will be different. im also going to suggest not launching over 4-5 psi the first few times to get a feel for how the car does.

its going ot be an entire new animal coming out of the hole on the antilag

re: Fasteddis Turbo 3.1/3100 Hybrid
 

Ok dave. Ill toss back on those old slick I have as the new ones are in my friends trailor so I don't have to lug them to the track. Ill see what it does out on the pavement tomorrow If I get a chance. Ill keep the boost lower. I have no idea how its going to act out of the hole, so ill keep a eye on it.

re: Fasteddis Turbo 3.1/3100 Hybrid
 

Ok theres no way I can test the anti lag on street tires..lol It makes for a good burn out though. I got 3psi then launched and it was just a cloud behind me. Im going to leave it as is for now. This is with the normal spark table just retarding 9.9 on the msd box and 2600 rpms. Ill just have to play with it at the track come Friday if its hopefully nice out.

Remember how I said the car had some boost control issues the last time out at the track?? Well I finally got to datalogg and see the issue.

It seems that my wastegate duty cycle that I told it to use because of its history is now not enough. Which tells me I have a tiny leak somewhere. I was running about 35% DC to get my 12psi I wanted. Now im at 50%dc to get the 12psi I want. It does make the commanded boost but just takes time to step its way up there.

The datalogg look crappy. I hit the boost hard and spike to about 14psi for a cell then down to 9.8psi at about 28WG DC% then slowly up to the 12psi which takes about 5-6 seconds at least because I have it ramping up slow so the boost doesn't get away from me.

Now I just need to think and brainstorm on what its the root cause. Is it a leaky wastegate, BOV, piping or exhaust, vac leak. Its just weird that its just happending in the past few weeks. But im sure ill find the problem.

I could always go in and set the WG DC to 50% roughly but then im masking the issue. Now that I have a anti lag that definitely works, is this a option as the thing still spools up just as fast as before. Its pretty instant. Takes about 5 cells in excel to go from 0 o the 14psi spike. That's about 1/2 sec, so its still spooling quickly as it should. I also plan to go in and fix the boost spike. Its just because the WG DC% is set to 99.9 for too long as the boost hits pretty hard and just needs some finessing...lol

re: Fasteddis Turbo 3.1/3100 Hybrid
 

Also whats your thoughts on running about 21.5* of timing for the most part on the 12 psi? The car seemed to like it. No detination at all. But I was just woundering as last year I ran way to much and don't want those detination problems again. My intake temps are high but 160* isn't to bad when you start with 120 degrees and floor it to 110mph. Thank you alky for getting me by. But I do need to mount a intercooler on there in the future for the DD.

re: Fasteddis Turbo 3.1/3100 Hybrid
 

need some cheater slicks to run the streets ;)

best summer ever in Toledo, I bought a 9sec drag bike and plated it, though the tiny 7in slick on it was easy to not get noticed by the PD, though lots of bikes got a good look at it ;)

re: Fasteddis Turbo 3.1/3100 Hybrid
 

I do have a set of et street slicks. There cheaters but as loud as my car is and as in bad of shape as those tires were I just said, screw it, ill just fry off the street tires once... Lake twp cops are assss' when it comes to fast loud cars in there area...lmao

re: Fasteddis Turbo 3.1/3100 Hybrid
 

Why I said Toledo, yes you must go into the city where they don't care, I member a guy in Walbridge had a wheelie bar on his [mine had an extended swingarm], he had to idle down his road and turn right to imediatly leave or he was harassed. That was when nightly there was drag races down end of main street by the river headed into Oregon from Toledo, use to be a dead end into docks. TPD didn't show up unless someone called about noise then just made us move.

re: Fasteddis Turbo 3.1/3100 Hybrid
 

???????????????????

re: Fasteddis Turbo 3.1/3100 Hybrid
 

sh!tty weather in the area. im glad I dont live there anymore:lol:

re: Fasteddis Turbo 3.1/3100 Hybrid
 

12.90@104mph with NO 2 step or antilag. I upped the boost to 12.5psi and also hit a best of 1.788 60 foot time. Ill add more tommorow

re: Fasteddis Turbo 3.1/3100 Hybrid
 

congrats on ur first 12 second pass and new best 60' any video?

re: Fasteddis Turbo 3.1/3100 Hybrid
 

ill upload the vid later this morning and the slips. I got a good vid of the 12.90. Thanks man it was a relief to finally hit the 12s strong

re: Fasteddis Turbo 3.1/3100 Hybrid
 

theres alot left in that thing still

btw me and u are the only ones to break 12's without having to run 15-18psi

another couple weeks and u should be in the bottom of the 12's possibly 11.90's when fall comes around

re: Fasteddis Turbo 3.1/3100 Hybrid
 

Heres the pass

http://www.youtube.com/watch?v=Szknh...ature=youtu.be

Heres the slip for it

http://sphotos-f.ak.fbcdn.net/hphoto...91980794_n.jpg

One happy thirdgen owner today. Makes me so happy that this lil iron headed beast was capable of this.

re: Fasteddis Turbo 3.1/3100 Hybrid
 

:goodjob:

re: Fasteddis Turbo 3.1/3100 Hybrid
 

:thumbsup: It was a bump in the road I never thought Id get to. Its surreal to think 2 years ago I was running 17 flat in this car.

re: Fasteddis Turbo 3.1/3100 Hybrid
 

any chance u have a datalog for the 12.90 or a datalog from ur other run along with the slip ?

i want to check and see how much that converter is sliping

by looking at the slip the car layed over about just after the 1/8th im assuming this is were it shifts into high gear

by all rights going by 1/8th time and mph that should have been around a 12.5/6 @ 107-8 mph

re: Fasteddis Turbo 3.1/3100 Hybrid
 

Do you have LCARB'S ?

Your car squats alot. I bet they would help.

re: Fasteddis Turbo 3.1/3100 Hybrid
 

he doesnt weve been recomending them to him for a while though, but i know how it is gota slowly save up and get one part at a time

ill tell u what watch his vid in full screen at half speed , he launched and it hit the tires hard then put 1-1.5 rotation on them and then she left hardddddddddddd

after watching that vid in slow motion id say the suspension is working pretty damn good the way it is , i dont know if id change anything , unless traction becomes an issue down the road or while using the antilag/launch control

re: Fasteddis Turbo 3.1/3100 Hybrid
 

I don't have a log on that but I did log a 2nd and 3rd pull on the street. Ill be sure to upload it tomorrow. Just got off a 12 hr work day so its bed time for me...lol But anyways, the converter rpms aren't slipping too much that I see, but I really would like to get deathsaars badly!!!



I box welded the lca's It was a cheep thing to do last year. But I played with the adjustable rear shocks and I like where its at. I run 13.5 psi in those rear tires and think a 1.78 60 foot time isn't too bad for foot starting it. It sure did feel fast!!

re: Fasteddis Turbo 3.1/3100 Hybrid
 

Heres a vid of the 2 12 second passes and some other stuff.


Heres the 2 turbos I got for free. One is locked up and the other has a oil seal leak. That things are so small. Mabey it would be good for a 20hp lawn mower after all..lmao

re: Fasteddis Turbo 3.1/3100 Hybrid
 

Major issue!!

Cr was acting rich on first pass tonight. Went to do a burnout on 2nd pass and the car died. Tried to start and it sorta started but was barely running and wanting to backfire. The tach was also very erratic when cranking the car over. Bad ICM??? Thanks for any inside fellas.

Also I'd have to floor the car to get it to even try to start, could see the flames in the down pipe, it was that rich and off time.

re: Fasteddis Turbo 3.1/3100 Hybrid
 

seems like it could be.

time to upgrade to DIS? :D

re: Fasteddis Turbo 3.1/3100 Hybrid
 

check icm and plug wires if the plug wires arc or u get missfires the tach will jump around

re: Fasteddis Turbo 3.1/3100 Hybrid
 

It's really bad. It happens suddenly so ill have to check the ICM in the morning and pray that's the problem.

Sux pushing the car off the starting line and towing it to the trailor with the golfcart

re: Fasteddis Turbo 3.1/3100 Hybrid
 

its not a racecar till its been pushed and or towed atleast once

trust me its not the first time it will happen to ya


were u using the antilag? it is possible u fuel fouled the plugs , u can also bypass the ignition box to see if that went bad

re: Fasteddis Turbo 3.1/3100 Hybrid
 

In my experience the DIS setup is much nicer to work with. The ICM/coils seem to be more reliable and there's no need to mess with a timing light. That being said, I cooked a set of coils last week from the heat I think so I'm going to have to make a heat shield for them.

re: Fasteddis Turbo 3.1/3100 Hybrid
 

I think it was called the excitor ring on the dizzy. That was literly falling off. No screws were there holding it in. So I got some new screws put some lock tight on and it ran fine again.

Im seriously woundering if its my cam or the heads that are limiting my 5k+rpm power. I swear this car is just slow above those rpms. The cams just a 260 grind. Would a more aggressive cam help? After forgetting to shift into 3rd yesterday and taking it to 6700 rpms I relized how much power im loosing up there. About 3-4 tenths of a second slower in the 1/4 mile just from that 700rpm late shift.

re: Fasteddis Turbo 3.1/3100 Hybrid
 

its going to be heads or headers limiting ur power i turned 6,500 rpms witht he 260 cam no issuse

what valve springs do u have on the heads? could be floating the valves as well which will drop power off fast
