how much WHP do you guys think could be had with this setup on 91 octane if my evo was already making 233whp and 235ft lbs. ( yes I take good care of my evo) oh yes and any ideas on what short ram turbo intake to get?

 

anyone wanna comment?

 

On a dynojet I would guess around 300-310WHP on a Mustang dyno I would guess 270-280WHP. Mainly because you are runing **** water 91 octane.

 

bump. what about dynapack?

 

could this setup be my ticket to 300whp? will a walbro pump help or hurt me with this setup? I'll probably be boosting to 21 psi on 91oct.

 

i got jet hot coated manifold turbin housing and o2 housing by buschure.... and exhaust with no cat... those are not power adders like cams ,alky kit.....therefore you ll notice alittle difference in power! not much..... those are just there to help better flow ~
just put alky kit with methanol and boosted up to 28psi on stock turbo! you will love it~
this is real power u are talking about.

 

I like the HKS intake. But i wouldnt do this until you are getting ready to upgrade your turbo. And if you are planning that, then make sure you dont buy an intake, and then the kit already come with one. Oh, and how is your exedy clutch? I am thinking about getting that same one and just wanted to know if you like it or not.

 

I'll comment. Yes, you could be somewhere in the vicinity of 300 whp. More than likely below rather above. I'd say j8 is probably on the ball with his estimate. However, I don't know your flash variables. Walboro won't be of any horsepower gain at the moment, however it would be more for peice of mind and maybe less problems down the road as you get heavier into the mods.

my .02

 

hmmm.......yes, that's what I was thinking also, but if I were to have a flash for 100 oct race gas I would make that 300whp mark no?

 

pretty much it is just exhaust, intake, and tune for your power adders would not look for it to be above 285whp, good luck depends on depth of tune.

 

Are you guys kidding? I made 312whp with just turbo back, boost controller and reflash. This was on 93 octane but i run 94 just to give it a little extra safty..

 

Personally.. I dont think 300whp is fast. Get in the higher 300's and you'll think its fast. You can make 300whp with just a intake, boost controller, tbe, and a reflash. Or close to it.

I recommend you get better intercooler piping, a better intercooler, the JDM bov is good, get a manual boost controller, Walbro 255 fuel pump, and a reflsah (Precision Dyno or Dynoflash).

 

Nice bag of groceries you got there. The clutch will make for a nice improvement. Get some cams before you put the check book away...

 

+1

he** alky would be nice to

 

Definately get a fuel pump. I was going lean (EGT 950c - 1000C briefly) with just a full exhaust and tune after several laps at the local track. Long pulls up canyons will eventually overrun the stock pump. It is not too expensive and necessary to accomodate future mods.
