my thoughts exactly, but I would go with a WR from switzer.

 

Just go witht he same setup that Chris has from AMS and you'll be VERY happy!!!!!!!

....................I think you all know who I'm talking about..........

 

Sorry, that was a typo on my end. Should read 400whp in my post. 91 octane, dunno about that, 93 definitely. Pushing a lot of boost on 91 is just asking for trouble.

 

Post dyno #s after u get car back to shut every one up

 

lol will do...will be next week hopefully. i trust the tuners with my utec any hopefully get some good numbers. doing a 91 map and 91/100 mix map. then a economy gas saver map for 87 octane.


joke

 

I'm thinking about alcohol kit for my car too but it's not just spraying and make more power. Mixing alcohol in the engine compartment is like playing with fire, some safety concern need to be addressed and so far none.

 

Ah, ok ... now it's making sense.

Unfortunately nobody seems to have dyno charts for your turbo on an Evo, but if you go by what Agency Power has posted as part of their advertising, then 400whp is not going to happen on your turbo with 91 Octane. Furthermore the spool up is going to be atrocious. As other people have stated, 23psi on 91 Octane is too high. Keep it safe(r) at a max of 21psi, which if held until redline may still be too high.

If you're going to go with alky (good choice for what you want to do with the car), then I would say go with a GT35R and call it a day. You'll easily make more than 400whp (more like 500) and you should be able to stomp the local ricers all day long.

Sure! Here is the lowest dynoed for 91 oct that I did at Tuning Technologies here in So Cal. The boost is around 22 psi and not finish tuning the SAFC-II on this dyno yet. We were having problem later when tune the boost higher to 26-27 due to spark-plugs gap (maybe) and maybe the stock-turbo dynoflash (just maybe). The car was pulling timing with higher boost so I need to identify the cause. I just fixed some bad gaskets and will come back for another run next week before heading to the drag. But running 91 oct daily with 22 psi on GT35r is so much fun and no problem at all. Don't let some "other" guessing confusing you.

 

Trust me, I'm not confused. Look at my thread from last year entitled "pump gas power." Do a search and you'll find it. 472awhp on 91 octane without alky using a smaller turbo than you. Again, my point is if you're not going to run C16 (high boost) you do not need a GT35. Also, this same setup put down 600awhp on C16 and ran 11.4 @124mph at Bandimere in colorado 5800ft absl. No guessing here.

It will be interesting to see what his setup (twin charger) will do on 91 octane:

Are you sure the graph is whp? I looks to be SAE corrected.

 

It is SAE corrected for altitude. The dyno is at about 6000ft absl. I'll admit that it may be opptimistic but I have the time slips to prove that it was close enough. This car made just under 600awhp on this same dyno with C16. It was then shipped to Philly (sea level) and put on a dyno were it's power was within 15awhp uncorrected. Altitude makes a huge difference and from what I've seen first hand a 1.2 to 1.26 correction factor is fairly accurate. The best test is the track and this car with C16 in it ran an 11.4 at Bandimere in Colorado. Altitude corrected I believe that's almost a 10.9.

 

^Sorry, I thought you were quoting my post.

 

why do i think the result of that will be very uninteresting? you can only drown out so much boost with ****. so with that... you might be able to boost by a decent rpm with the twin charge... but everything else will be same as an efficient turbo on **** water yeah?

you can get close to 400 horses on the wr the 3071 or if you're greedy the 3076 or 3037. that answers the question...

 

I'm not trying to get into any debate over hps here. Your car has more power then it's great for you. I'm still in the process of building and tuning my car.

I'm just try to show that the 400 WHP is achievable on 91 oct gas as oppose to some mentioned that it cannot be done. It's also mean to help the original poster of the thread that his turbo is capable of hitting 400 on 91 oct. too since it's very close to the GT30 & GT35Rs.

I'm using my car for drag a lot so YES! I do use race gas when it needed. And for the turbo, a little different in size doesn't mean it'll perform better than the other, the tuning, the parts and the condition of the car play a very important role. I'm using SAFC so not much control I have over the tuning but I want to see with a simple setup and easy tuning, what can it achieve on the EVO.

FYI, the 600WHP car you mentioned above, it's kind of slow for the number that it ran for that kind of power.

 

My point is this: For someone who only wants to run 91 octane and not C16 you do not need a GT35 turbo to reach his goals. I wanted to show a dyno of my car making well over 400awhp with a smaller turbo. A GT35 turbo is awesome if you are going to run C16 and crank up the boost. A GT35 is also awesome if you are going to run alky and crank up the boost. THe poster of this thread says he doesn't want to run either alky or C16. For what you do it's the perfect turbo. For what the originally poster wants to do it's probably overkill. It's not an ideal pump gas turbo. He'd be better going with a slightly smaller more efficient turbo IMO. Just trying to help him with his decision.

Remember 600awhp is altitude corrected using a 1.25 correction factor. At this altitide my turbo made a max of 28psi (same turbo makes 34 psi at sea level). When we dyno'd it at sea level it was back up to almost 600awhp uncorrected. So the 1/4 times that I posted are actually very good, 124 mph is amazing at Bandimere in a car weighing 3300 lbs. In other words, you're wrong.
