MAP EF-series Turbochargers results thread
I agree with you, but for the price they wouldn't make a huge enough difference like they would on an 8. If I do decide to go the cam route, I'll look into the GSC S1 cams. Their range is 3000-8000rpm which is what I want. I like good low and midrange power. We'll see what the car does in a couple days. I can't see it making less than 450hp dynojet though on a built motor with supporting mods. With the stock motor, stock turbo, stock intercooler, stock upper IC pipe, stock turbo manifold, 5psi less boost, and smaller injectors I was making aound 380-385whp on VD. I can't see adding those mods, and that boost and only making another 20hp. Like I said, I guess we will see.
380whp with only injectors and e85?
you may want to get a second opinion. cams make a huge difference, be it low and midrange with a nice, mild cam or top end with something more aggressive. cams are one of the single best mods you can make to these cars. there isn't many better ways to get the car to run how you like.

I've seen differing tuning and setups on the EF 2.5 with numbers all over the place. I guess the speculating isn't getting me anywhere. It's best to just wait until I get the car back and see what it does. I just don't see the car not hitting 450whp dynojet with a built motor and the mods listed.
With good gas (not ****ty 91 pistane) and a built motor on an evo 9, I think 450whp dynojet should be easy.
On my EF4 I broke 500whp on like 22psi on 93 octane. obviously much bigger turbo, but I didn't even have to try for that.
No sense in speculating or bench racing any further though, just wait until you get the results!

They do if they have higher compression or more displacement.
I don't even know who is arguing for what anymore lol.
91 vs 93 oct is HUGE though if that is what you are getting at. On a big enough turbo at enough boost it can be worth 20-50whp easy.
91oct sucks, simple as that.

Me either but I will say to whoever asked the original question is you never know until you try. Some cams will definitely help though.
Okay, got the dyno tune done. Final numbers were 363whp/320wtq on their low reading mustang dyno. Back to back with Hennessey's dynojet, this dyno read's 17% lower. So for comparison, the car would do about 425whp dynojet. Less than what I thought, but still stronger than before, and not bad for pump gas. The biggest hindrance was the cat on the dyno. With a test pipe, I would have been able to make a little more power. That became even more evident because about an hour after I left, the cat just about completely plugged up. Pretty sure it was plugging on the dyno. The car won't boost right now, and it's bogging bad. I'm at work though, so after work I'll be yanking the cat and putting on a test pipe.
Want a miserable trip? Drive from Dallas, TX to Baton Rouge, LA in an EVO with a plugged cat that can't boost. 6.5hr trip turned into a 9.5hr trip, and having to get running starts at bridges, and hills. So the Mil.Spec 100 cell race cat isn't up to the task...lesson learned.

Seeing that you have a 9 you can get more aggressive with the cams and still have good drivability. S1 would be a waste of time. S2 or S3 is the way to go since they all cost the same. Do a good spring/retainer set and go for it. On 93 cams make a huge difference. If you can just pour on the boost with E85 it isn't as big a deal.

lol
The only other thing I can think of is that my Grimmspeed 3port might be going out. I haven't heard it clicking, but that could just be because of the extra noise in the engine bay now, or because of the turbo not spinning because of the plugged cat. I'm going to start with replacing the cat with a test pipe, and go from there.
