GTM Stage 1.5 Pulley Recommendations

kentmo280z · 05-29-2018, 05:33 PM

I have the 1.5 kit. Tried the 90, 88 & 85 mm pulley's. I got best results from the 88mm pulley. the 85 mm pulley seemed to lose top end power. I was remote tuning at the time of the changes , but the power was better overall/top end with the 88mm .
Final dyno tune by Dynosty- 479/360 to the wheels with the 88mm.

Do you have any fuel system modifications done? I'm also looking at doing a return line fuel system along with 1000cc injectors and a DW400 fuel pump upgrade.

I used the Fast Intentions Fast 500 fuel return kit, ID1100 injectors and the fuel pump (walbro 255 )that came with the gtm stage 1 kit.
( I upgraded to the stage 1.5 kit and kept the stage 1 fuel pump. )
