Well, I have been the one disspointed with my cars power with my mods. Today helped a little bit. Still not where is should be. Was 281WHP/271Ft lbs at Pruven before my Buschur MBC went in. 1st set it at 21.5, tapered to 20 at 5000 rpm and held there. Dynoed with that setting and stayed at 281HP, but my torque went to 282. Dynoed in 3rd and 4th. Then my 3rd and 4th runs i upped the boost to 22.5-23, tapering to 21-22. WHP jumped to 297 and torque rose big time to 308 ft lbs. SO all in all im happy to some extent. My fuel is way rich though. So all in all with the MBC from Buschur, WHP went from 281 to 297 and torque 271 to 308. Not bad for 75$. Still with my mods I think I should be about 310-20 WHP. Oh well, im trying ot get up my dyno sheet but im having trouble making it small enough to fit here. LATER!!!

 

That's pretty low for an EVO with those mods. Even with the mbc. How rich are you running?

From 3000 rpm on, bumped up and down from 10-10.6. And I agree, it is low, about 20 WHP low, from what a couple tuners/EVO owners have told me, its either the shop who put my cams in didnt time them right, or, which was obvious to me at the time, my last reflash didnt gain me crap.

 

yah most likely its the cam timing... tuning the fuel is going to free up a good amount of high end power as well, what octane gas are u running?

 

Ouch all those mods and only that much Hp. Something is def wrong with it. You should be at around 310-330 with that setup....

Sunoco 94. Well supposedly Pruven installed the cams right, but the tuner I went to today said if they did it would have added a heck of lot more power than it did.

 

Sadly it seems that IF you want to run the more boost you are going to need to re-tune the car as the 10.6 a/f ratio is indicating it is running too rich

As you last custom tune was tuned for lower boost, when you are raising the boost the tune is being thrown off

I'd say there is at least 10 - 15 whp to be found in leaning out your car and that would put you right in the range of where we would expect you car to max out on the stock injector and fuel pressure with stock fmic

I would suggest waiting the way it is till you can put the bigger 660 injectors in and a fmic - that should get you to about 340 whp

Another option would be to turn back down the boost slightly and enjoy a nice safe tune at a slightly less whp range than your peak

IMHO 300 ft lbs and 300 whp is not bad for stock injectors - - - I heard a rumor on of the cars at the SCC shootout only dynoed 260 whp with cams

Anyway - call me if you need any further input on my end, but it looks like you need more work on the tuning IF you want to max out the maximum possible power

 

I am not trying to start **** but I know the Vishnu tuned evo's are getting 310-320 on that same dyno without cams, with cams they get about 350whp. Sounds like the ECU needs some tuning because you have the parts.

 

Your right - when he came to his tuning appointment he had no boost controller. Just turning up the boost is going to make more power - but if he wants the 310 - 320 MAX that this combo can yield it will have to go richer.

On the positive side - his brother made like 310 whp and 315 ft lbs on the same dyno with the Dyno Flash WITHOUT the cams ! But WITH the tune matched to all his mods

 

310-320 is good for no cams and that's the same shiv is getting on that dyno. You should be able to get 350whp with a good tune on cams. Cams are good for 30whp if tuned correctly. Also he should add the cam gears for 200 bucks and put the stock intake back on

 

I am glad that now you are the authority on tuning so I can PM you or emila you the next time I need some advice !!! I guess we will all have to wait the 2 - 3 months till the SCC comes out to really find out who does what on a dyno jet awd dyno

 

lol we will, I know cams make the power though Al. You know it's pretty damn easy, computer, turbo back, cams, and cam gears and your are done. Once people start doing the HKS SSQKSEEOIA BOV and intakes it screws things up. If you come to Atlanta again I will rent a dyno and we can do a with the XEDE dyno and then with your flash and see what works better same car same mods. I would really like to see how it does. I still don't like this xede 100%, sometimes when it's cold it runs really bad until the xede "Clicks" and it runs it's map. Last night after playing poker I left @ 3 and it was about 25 out and my car ran like **** because for some reason the xede never did it's clicking thing. I put it in netural and it stalled out. I started the car and it initialized and was fine. That's why I don't trust it 100% lol what if I had that big turbo on it?

Thats what I thought, AND heard from MANY EVO owners. Like I said before, osme have said the shop who installed my cams screwed up the timing. I dont know. I dont have the $$$ to keep handing it out. Ive spent over 2500$ on my car int he last month. Most well worth it. Although my last reflash and cam installation came up short. My Cams got me 18WHP and reflash added 3WHP. Thats 21 for 1210$. My Buschur 76$ MBC added me 16 WHP and 36 ft lbs.

 

keep it clean guys

I PM'ed you.
