The 96mm pulley will only get you about 440-450

excellent. and yeah thats what i was thinking.. generous dyno lol.. and 450 is right where I'd like to be for rainy season if she does get driven.

Mkai,

thank you good sir

I'll definitely have to scoop that up from you soon.

No problem, keep us updated.

heres my dyno sheet from today. Not bad at all, IMO. car is running strong. No tune, art pipes, z1 post maf tubes & K&N drop ins.

I'm gonna have a 96mm pulley on for now. Next spring, I'll throw the 92mm on and dyno again. I'm getting a baseline done tomorrow. I have post maf tubes and k&n drop ins, plus the art pipes installed on a stock tune. I'll post results as soon as I can. All in all, 516whp is insane. I'd be MORE than happy with 490whp and no meth.

on a side note.. that dyno graph goes to 7800 rpm. O_o

Good luck, when your ready for the 92mm pulley let me know because I'll give you a good deal on the lightly used one that I have in my garage.

When you go stage 2 is the only difference the larger -91 trim Rotrex?

Reason I ask is because...

I was the first to run the -91 on my Toyota Tacoma. Underdog Racing Development made the kit with a -81 but I asked for a -91 with a larger pulley.

What we ended up finding out was that I was making way more midrange power and a peak of about 450rwhp on a less aggreesive timing map on only 9.7 psi. While the guys running the -81 trim made less midrange and took a whopping 15 psi to hit 450rwhp.

The -91 trim also provided significantly lower boost temps

Wonder if GTM has tried the -91 with a larger pulley.

The 1.5 kit does use the smaller blower but it provides more mid range torque and in my case it has also given me more hp than stage 2.

I am curious what you are comparing to? Did you try stage 2 and then go back to 1.5?

There is no one on this forum with stage 1,1.5,2 that has more power than me plus dyno results are on the forum.

I thought Jamaica was close to 550 WHP with the Stage 2 kit and he blew his 7AT then sold the car.

But the thing that not a lot of people know is that they use the smallest pulley possible to get those numbers,I should know I tried to buy that pulley from Sam he won't sell it to me claiming it will over spin the blower.
