Let me first give thanks to Brian Tooley for the cam, Jeremy Formato with Fasterproms for the tuning, and Fat Body Performance for making all the magic happen. I've been beating on this old stock LS1 since 2005. I've put tons of bottles through this car to see how far I could push it. I was able to make a best pass of 10.74 @ 123 mph, 1.42 60' (6.78 @ 99 mph). I figured I accomplished my goal with the motor stock and it was about time to add some power to her.

This was my starting point:

Lid
QTP 1 3/4 Headers
3" exhaust x-pipe dynomax bullet mufflers dumped
Tune
NX 150 shot - wet - shark nozzle
FTI TH400/Converter
Moser 9" Narrowed 3" each side (5.5 bs rims )
28" Radials



No Surprise. TH400/Big Converter/9" eats up some power. What you'd expect from a stock LS1 with a couple bolt-ons and some giggle juice.

New Setup:

Brian Tooley Racing Cam (235/242 .620/.594 111 LSA)
BTR .660 lift valve springs w/ titanium retainers
Chromoly pushrods
Comp Cams Rocker Arm Trunnion kit
FAST 90/90
85 mm MAF
98 mm Lid
42 lb injectors
u/d pulley
Racetronix fuel pump kit
LS6 oil pump
single roller timing chain
Nitrous Outlet 2 stage 90 mm plate
Lingenfelter 2 step



100 shot, then 2 at 150. Retarded 4 degrees with Lingenfelter 2 step for 150 shot.



The 420 pull was with 28* timing, then we backed it down to 26.5*



Here's the video:

 

Any thoughts on why the graph is all over the place?

 

It looks like a shift is happening but possibly dyno losing signal?

 

Great numbers from a fellow Need2speed member!!! Looking and sounding mean man.

 

I just added a lnc200 to mine and need to get it set up to pull timing instead of being pulled all the time for the n20. Also get a tune while its there. Whats a ballpark that he charges Im in Clearwater so its not to far.

 

nice numbers, what was your total timing with the n2o?

 

My first thought would be a faulty design in the nitrous plate

To be honest, I'm not really sure why there's the hit, dip, then goes back up. I was thinking at first it might be a little tire spin (I know it spun a little on one of the pull). It's consistent each time... hiccup in the dyno reading?? Could be. You can see on one of the motor pulls where the dyno skips a little and has a torque spike. I don't recall hearing anything funky then or when I watched the video. It looks a little funny, but nothing that makes me have a 'concern'. In the past, I've had dynos do a complete loopty loop on me.

 

You're probably looking at about $400-$500 plus dyno time. And then I believe he charges $200-$250 for a 're-tune' later if you make changes.

 

Thanks. Total timing would be 26.5* - 4* pulled with LNC2000 for a total of 22.5*. With this cam and my free flowing exhaust... we could have hit her with more timing i'm sure. 24* with no issues. We were not seeing knock and then pulled timing... just stayed conservative.

 

the crazy swings in the nitrous graph is most likely the converter causing crazy reading on the dyno. My old combo did the same thing. You should use mph instead of rpm to view the curve. It will smooth out the graph and you can calculate the rpm from the mph on the dyno.

 

Nice numbers but graph is crazy lol

 

You're probably right on the converter causing the funky dyno graph. If you notice on the first graph, they used speed to smooth out the graph. Could have done the same on this one but oh well. I'm not too concerned about it. The numbers I'm interested in come at the track. Not going to say I wasn't surprised and excited to see what she did put down though.

 

very nice numbers!

just curious whats the fastest cam only nitrous ls1? is it the 9.85 on the stock cube list?

 

i want ur tq curve3 . what converter u using? sry i know this is old thread

 

Dude, you're not texting to your buddies. Use whole words.

 

What gears are you running and what rpm are you shifting at

 

Iam very impressed with the fact you are driver modding a M6 car with nitrous!!! Keep it up bro that thing is making serious numbers too!! Take care of her

 

Almost 5 year thread! But nice numbers

 

sounds good
