I dont plan on getting a bigger turbo any time soon. Has anyone taken the stock turbo to the max yet? What mods do you have and how much hp will it put down at around 25psi?

i know u said ur not upgrading the turbo, but here is one with blouch dom2, 25 psi, stock exhaust with testpipe, pump gas making 410 wheel

 

We recently tuned a stock turbo/cams Evo 10 to 380whp with E85 on our mustang dyno.

The turbo itself is maxed at this point in my opinion, at least flow wise as the lb/min log basically flat lined. More flow in the exhaust, porting and upgraded cams will add some additional power but getting close to the point of small returns compared to investment.

For reference, the highest Evo 9 stock turbo on our dyno so far is 401whp on E85 and it was enough for 11.4@120mph full weight.

 

Cool thanks for the info. Do you think the kelford cams would be over kill for the stock turbo? There probably wouldnt be anymore gains if all other bolt ons were already installed right?

 

Kelfords are a waste on stock turbo. We have tried them. 214-B is likely the best option with beehive springs as the 214A's we have tested were not very impressive.

 

We haven't had a customer upgrade cams on a 10 yet so we unfortunatly do not have any data at this time. We haven't seen a huge gain with mivec cams on the 9 while still on the stock turbo with all the proper supporting mods, I can see this trend continuing with the 10 as well but won't know for sure until I see data myself.

 

My impression is that the stock turbine housing and wheel really become a choke point. So you're not going to see really big gaines with cams until you go with a bigger turbo with a bigger turbine housing.

 

Even with an EvoRed, we have not been impressed.

 

FP Red you mean? It uses the stock turbine housing
