Mustang Turbo

4088 is good choice as is .72 exhaust. it sould be in full boost by 2500 or so. if you run an auto with stall ever sooner.

Heh, sorry, I don't mean to brag or call attention to myself, but I would be running two of those and thinking that I should see full boost 15# around 3500-3700, and if I choose to run even more, say 30, I'd see it at 4500 to take me to about 7500. So, while my application may be different, if you read the maps, it's the perfect turbo for some nutjob with a 4v.

My bad I didn't mean to derail by telling him to get a blower. I agree, an appropriate turbo setup is great, but it seemed like he was in way over his head with these turbo setups.

In his other thread he stated not replacing stock internals, which limits him to ~400 at the wheels. Turbo setups are mighty expensive to limit oneself to those power levels imo. Unless you make a custom junkyard setup which works great if you know what you're doing

/derail + comments about blowers (my bad $

a blower limit is 400-425 rwhp and 12psi, but a turbo will make 500rwhp with less boost and live a while on SOME stock blocks.


i will always agree boosting a stock block is a mistake. but everyone cant build their own forged motor. so i understand why some do it.

for me and others forged, i was afraid early on the boost it past 14, but not anymore. you simply cant do that with stock internals. and really they arent that expensive to buy and balance.

my next shortblock will use billet stuff. im already deciding which parts.

stock cobra crank is the only non-billet part. i want to run 20+ lbs without fear. right now my parts are really only good for maybe 700rwhp.




hey thread starter. go to garrett turbo and read everything and do the calculations you get the right turbo that way.

if you are willing to keep it below 11psi and not run it WOT for 5 minutes straight it will be fine.
