I have a stock 2000 M6 z28 and a buddy of mine just got a new srt-4 a few weeks ago for mods he has a boost controller, blow off valve, intake, wastegate... from a 30mph roll he only pulled a 1/2 car length up to 100mph and from a stop it was about the same i got him off the line and at about 60mph he started to slowly pull.. im kinda pissed but were good buddies but i gave him props for the fast car.. i guess its time to start moddin

 

heck yea dude, get some boltons on that ride

 

well im ordering an SLP airlid tommorow along with some pacesetter headers and y-pipe i think is this a good header/y-pipe set up or should i look for something else.. http://cgi.ebay.com/ebaymotors/ws/eB...e=STRK:MEWA:IT i dont wanna spend alot of money because i wanna get as many parts as possible but dont wanna get crap.. whats your guys opinion?

 

You didn't mention anything about a catback, are you wanting to do headers/Y-pipe before exhaust?

If you only lost by half a carlength then a lid, free ram air mod and a catback should get you ahead of him.

 

first of all you should have pulled him are you shifting at 6000 rmp i pulled srt-4 that had the stage two kit when i was stock.


get an electronic cutout with your header ory combination and dont get a catback that way you have the best of both worlds loud and quiet. do the freemods they make a differents and get new spark plugs. have they ever been changed on your car, it might be time.

 

well the car came with a flowmaster muffler so i thought that might be enough for a few weeks before i can get some new stuff.. the car only has 37k miles on it do you think i need sparkplugs?? and yea i was shifting at about 5900rpms... his car was very quick it pulled about a car lenght on my buddies 98 z28 too... but im kinda new to the whole ls1 thing ive owned lots of 4cyl turbo cars but give me your opinions if you guys say catback first then ill do that.. btw thanks for the help guys

 

thats one 4 banger that moves w/ mods...I think it was more your driving though then his car being faster

 

A stock LS1 will not pul a well-driven Stage 2 SRT-4. Sounds like you beat the driver.

 

Maybe you need to tune your car up?

 

i have pulled several srt-4 when my car was stock some with stage 2 and one with a bov, IC piping and a 75 shot. i also pulled an ls1 that made 328rwhp. this is all when my car was stock.

you really should pull every gear when the needle is on the 6000 mark which is right befor the rev limiter at 6200 rmp.

 

i doubt that you pulled on a srt with those mods.. there extremely under rated similar to the LS1's and especially with a 75shot turbo cars tend to make almost 100hp at the rear wheel with a 75shot so i doubt you stock would take one of those.... ive been readin the srtforums this afternoon and from the posts those guys with boost controller, intake, wastegate, and bov are running consistantly low 13's so my 1/2 car loss hardly seems like driver error... but idk im sure i could have been better but from what i see now, me stock vs. him modded he just has the faster car right now

 

Back when I was stock back in July, I beat an SRT with an 8.9@81 and he had a 9.5@ like 78??. Before our track closed in NOV., I saw him run a 9.2. Not too bad at all for a 4 cyl!! There was one kid back in july running like 8.8's...8.7's. Dont know what he had??

 

@ the guy saying he pulled an SRT4 that had bov, IC piping and a 75 shot when he was stock.

 

It appears the difference between "beating an SRT in stock form" and "losing to an SRT in stock form" simply depends on whether you own a "107 mph stock LS1" or a "103 mph stock LS1".

I've seen both, and I've always been confused as to why GM would make cars with a 40-50 hp variance, but anyway...

 

I know this is off subject, but if I was running 81-82mph in the 1/8 stock...and 84-85 mph modded...what mph would that be close to in the 1/4, stock and modded. Got me a 3.73 gear coming real soon, too!!
