Benner Posted September 17, 2010 Report Share Posted September 17, 2010 Right now I'm sitting at a modest 14.3 with a 2.065 60' on bald street tires. Would like to get to a solid 13.5 on street tires if possible but may end up grabbing a cheap set of nittos or comparible price drag radials. The transmission is built enough to handle the extra power so no worries on that. Also the torque converter has been bumped up around 500 or so RPM (Can't remember exactly what he put in but the numbers were supposed to be around 500 to 750 higher than stock and it feels like it) Current mods thus far. 3.4 MPS (Scanned at the drag strip and .1 degrees knock at the top of 2nd gear) Intense Racing PCM 3 inch Catless Downpipe 104's 180 thermostat DIY Cold air intake with 4 inch tubing I'm sure I'm forgetting something Also planning on picking up Speed Daddy headers this fall but the rest will be over the winter After the mods I'll have it dyno tuned Also don't have the money for intercooling. So lets hear some opinions. Quote Link to comment Share on other sites More sharing options...
Tshensley Posted September 17, 2010 Report Share Posted September 17, 2010 the headers felt a good difference in mine. Quote Link to comment Share on other sites More sharing options...
Dammit Charlie Posted September 17, 2010 Report Share Posted September 17, 2010 I don't know much about those GTP's, but N20 always works great. Buy my N20 kit, put the 75hp jets in, and run atleast a 13.5. End of story. Quote Link to comment Share on other sites More sharing options...
Mr. Jones Posted September 17, 2010 Report Share Posted September 17, 2010 What are you trapping, 13.5 in a GTP is usually easy cheezy... Quote Link to comment Share on other sites More sharing options...
jeffro Posted September 17, 2010 Report Share Posted September 17, 2010 i shaved nearly a second off my time from just a tune. hit up dynotunomotorsports for an awesome tune that will net you 13s Quote Link to comment Share on other sites More sharing options...
Benner Posted September 17, 2010 Author Report Share Posted September 17, 2010 What are you trapping, 13.5 in a GTP is usually easy cheezy... Pretty consistantly 94 to 95. Best run was a 95.75mph with a 14.343. Quote Link to comment Share on other sites More sharing options...

Linn1647545492 Posted September 17, 2010 Report Share Posted September 17, 2010 Yeah i'm planning on taking it to him once I drop another pulley size. That would be the first thing I would do, pulley and a tune then headers. Quote Link to comment Share on other sites More sharing options...
2 Sweet Posted September 17, 2010 Report Share Posted September 17, 2010 Also planning on picking up Speed Daddy headers this fall but the rest will be over the winter After the mods I'll have it dyno tuned This. If you still don't hit 13.5's after those mods, you're doing it wrong. .1* of knock is really good. I had the same mods minus the pulley (mine was stock) and I would ALWAYS get a quick blip of 2.0* KR right when it shifted into 3rd at WOT. Are a lot of the L67 guys converting to E85 these days?

STEVE-O Posted September 17, 2010 Report Share Posted September 17, 2010 driver mod... I ran a 14.6 at 93 my first track pass ever. let alone on a stock gtp with 115k on the motor.. with your mods you should be able to hit A 13... only other thing i would say to hit a low 13 to a high 12 would be a cam and a 3.0...

2 Sweet Posted September 17, 2010 Report Share Posted September 17, 2010 Yeah i'm planning on taking it to him once I drop another pulley size. If you go smaller than a 3.4 you should probably look into an intercooler. And I'd still get a Gen V blower before dropping another pulley size.

2 Sweet Posted September 17, 2010 Report Share Posted September 17, 2010 Also, don't get to the point where you're spending a ton on the car. After the headers and tune I'd stop. So many people get an IC, cam, heads, blower, injectors, rockers, LSD, etc; and then sell or part the car out because they still have trouble hitting 11's.

2 Sweet Posted September 17, 2010 Report Share Posted September 17, 2010 = low 13's high 12's annnnd.... Price: $2,439.99 My point exactly lol. IMO it's not really worth it unless you do the work yourself and buy used parts Quote Link to comment Share on other sites More sharing options...
STEVE-O Posted September 17, 2010 Report Share Posted September 17, 2010 If you go smaller than a 3.4 you should probably look into an intercooler. And I'd still get a Gen V blower before dropping another pulley size. no need for a cooler unless going smaller than a 3.0 and you can do a cam with stock heads and a 3.0 safely all day long. Also gen V blower is larger so he would be making more power with the 3.4 on his gen V then the stock blower.. Also they are not cheap and he would need to either extend the fuel lines or get a new rail to clear a gen V. If he wet 3.0 on a gen V he def would need a cam intercooler and some heads etc etc... headers, 3 inch d/p, 3.0, cam, springs, intake, and a tune and you should be able to hit 12s if you can drive... headers, d/p, 3.4, tires, intake and tune you should be able to crack a high 13 Quote Link to comment Share on other sites More sharing options...

Does anyone run a 3.0 pulley on a stock M90? Quote Link to comment Share on other sites More sharing options...
Benner Posted September 17, 2010 Author Report Share Posted September 17, 2010 That would be the first thing I would do, pulley and a tune then headers. Can't drop any further on pulley size without more supporting mods. That .1 degree of knock would be horrible if I dropped a pulley size. These engines don't respond good to knock.

Does anyone run a 3.0 pulley on a stock M90? Don't want to invest the money on a gen V right now. I'll probably end up porting the hell out of this one. I've actually seen 2.8 on them.

I've heard of guys running with a 3.4 and having faster times than similar cars with a 3.2 or less. Smaller pulley size isn't always the answer Quote Link to comment Share on other sites More sharing options...
Main3s Posted September 17, 2010 Report Share Posted September 17, 2010 Best set up I had on my GTP was a cam, headers and tune. (of course I had the t-stat, plugs, yadda yadda) But I was running a stock cat back (minus the cat). and had a 3.2 pulley on the streets. Could run 13.2's all day on street tires (and 1.9 60fts) and with a little race gas and slicks I was running 12.7's. Quote Link to comment Share on other sites More sharing options...
