Whats with the .90 housings, i thought bigger was better? I dont have any issues spoolin a 80/87 with a 55 or for that matter a 80/96 with a 55, even in low range.

main reason I'd like to stick with a .90 is because I will be running stock cp3/injectors until the spare engine is done, and I can always loosen the AR down the road.

I still think a 1055 would work better for me compared to a 1058 for what I plan down the road with a built engine, dual cp3's and some 60's.

What do you consider spooled? Do you have any data to compare with what I posted above? Also, keep in mind my engine is not ideal for getting up on a big charger, which is why i noticed a difference when I switched to the different heads/cam. I believe that the looser housings will not work well with my setup, that's why I am sticking with the tighter housings

No, I'm being serious. At what boost, rpm, or egt do you let off the brake and start your pull?

And thanks for twisting what I had said. Noone needs 3300 rpm to make a turbo start to whistle;)

No problem, glad to help!

Depends on track and sled, 8psi 2000 rpms= soft lazy launch, 10 psi 2000
/2200 sligt lag moderate launch, 12 psi 2200/2300rpm, launches like a fircracker!, egts always between 900/1000 at launch. I started with a. 9 housing,bumpd 1.0 then 1.10,power and rpm went up, never noticed spool difference. Belive it or not, 96 wheel pulls up quicker than a 87!

I wonder why the 96 is quicker than the 87

Brian I sent you a link with a picture of that plug. I think you will like it better than the other one.

Dont know, even on the dyno, 87 strugled to light a bit more than 96, my though, same comp wheel, bigger wheel gives more leverage to push the comp into the boost. it shocked me, i was worried, then surprised!
