I tried to buy the 84mm pulley from Sam but he won't sell it to me.

fryzia23 · 09-07-2013, 06:23 PM

Do you get 93octane?

93 octane most all the time, 110 octane when I can find it to mix with the 93.

fryzia23 · 09-07-2013, 06:32 PM

That's weird. They told me as long I get 93 it will be fine with 88mm

I don't know either so I just dropped the subject with Sam.

I've got 92 octane here with up to 10% ethanol :/ hopefully I wont need meth on the 92mm pulley. We shall see. Order goes in next Friday when I get paid.. 4 weeks lead time. my FI exhaust should be here then. I'll dyno with both ART pipes and stock cats just to see what the difference is. 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

You can get 490 without meth but you will have to use the 92mm pulley,and the 7800 rpm is alittle high plus making 514.8 on 8 psi I think they have a very generous dyno.
The 96mm pulley will only get you about 440-450

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.

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.

Mkai0 · 09-08-2013, 01:37 PM

No problem, keep us updated.

snowsurfdirtx · 09-08-2013, 08:56 PM

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.

snowsurfdirtx · 09-13-2013, 10:39 AM

Going with a Defi red racer boost gauge and Aeroforce Analogic with oil pres/afr combo.

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.
