so much for the "Spool 3600-4200 RPM" claimed for the 750R I guess in their "technical" defense, they don't say "peak boost by X" Their right thoug the turbo is "spooling" between 3600-4200 rpms, along with 1rpm to until you let off the throttle haha.

I seriously doubt that the turbo would ever hit full boost by 3700, but 42-4500 is very possible.

You should also take into consideration that alot of the spool is in how aggressive the tune is done with fuel and timing during that RPM. There was for sure some spool left in this turbo, however with the fully stock long block we didn't want to push those limits.

Yeah there is no way it would be at full spool by 3600 on a stock 2.0L, but maybe with a 2.2L and some aggressive MIVEC it would be possible to get close. I'll get more seat time in a 2.2L block equiped car soon enough (http://www.teamiglooracing.org/?page_id=40) and report back what I find.
I know that it will spool slower than my GT30 which is 20 psi by 3600 in 4th gear but it should be around the low 4000 range on a 2.0L car. Also keep in mind that the peak torque hits on the Dynos quite a bit later due to less load. You also don't know if it was done in 3rd or 4th gear. On a 4th gear pull my car sees increased torque if I increase boost starting at 3800 and peak torque usually hits around 4200 at 28 psi.
I think the 750R turbo is likely hitting 20 psi by 4200-4400 in 4th gear based on power at that RPM with full boost around 5200 at peak torque. I guess I'll find out first had early February.

Thanks for the input...the runs were done in 3rd gear on the dyno, and you are correct the car will come on a bit sooner in 4th given the higher load. It actually feels alot better on the street than it looks on a graph.
We have been closed for the holidays, I will try to get you guys more data.
We have another kit going on next week if all goes to plan, so I will update you with those results...bit bigger turbo
