Topgunz - air to air upgrade

mikey1600 · 04-12-2021, 09:15 AM

Thanks guys, another mention, I drive my car once a month if lucky

so very little miles get done on it overall, are those pulleys right though? (previous threads I've seen them mentioned to get another 2-3psi) I'm only hitting 10 psi right now on current kit, straight through exhaust at 7k rpm~

I've got the 9lb pulley, opted for it when buying the kit, will triple check measurement though.

So get these studs also? https://www.z1motorsports.com/engine...hr-p-4755.html

redondoaveb - I see you have 680whp/530ft.lbs, what over and above have you done to get there?

I've done all the basics E85 fuel only - a2a upgrade/upgrade impeller/s1.se return fuel/larger pump/injectors/9lb stillen pulley, how'd you get 19.5 psi? what pulley changes are needed?

dyno graph is here pretty sure my FB is all public (keep in mind I am in Australia, our dyno's seem to read about 10-15% lower for some reason, so not chasing just a figure only but at least boost should be similar) - https://www.facebook.com/photo.php?f...20000..&type=3

You won't get near to 19.5 PSI with that Vortex SC no matter what pulleys/impeller you use.

I did (but I blew my motor)

I was running the 9lb, 3.47 jackshaft sc side and a 2.85 sc pulley. I blew my motor at that psi though. It made 16.76 psi with the 9lb, 3.47 jackshaft sc side and 3.00 sc pulley and still made 680whp/510ft.lbs. and was dependable. It didn't make boost as quickly as the 3.47/2.85 combo but in hindsight, I probably should have stayed with it.
