FP RED and e85 end of story easy day.

 

just because i have seen a couple of successfull hill climb evos...i would say 2.3L with a red or a green turbo...
from reading about...i believe you will also achieve simmilar results with a BBK tasty sauce !!

 

Everyone needs to keep in mind that just because XYZ car made 550ish HP on some of these turbos doesn't mean you'll be able to in hillclimb/road race spec. This is absoultely not a dig at anyone's car, just a for-instance. Hillclimbs are the worst kind of punishment you can put a turbo thru. You're able to put extra load on them from going up hill, and since you're going slower because of the up-hill, you have less airflow thru the IC and radiator to keep things cool.

Real world implications you ask? My PPIHC car last summer made 398/390 whp/tq (corrected) in Denver at 27psi (~5200 ft elevation) on a stock motor and FP White on E85. I take the car with the same MBC settings to 9400 ft, and I'm making 4psi less with nothing adjusted. To reduce the heating effects and the chance of overspinning the turbo, I turned down the boost further to make sure the car wouldn't overhead on a 12 minute run. We ran with it at 20psi and didn't experience a hiccup the entire run, but did run into some overheating issues (coolant temps) for a brief portion of our race-day run when we were in the steepest/slowest part of the course.

I don't know of any other hillclimbs that are longer than PPIHC, so the OP may be able to get away with running a more aggressive tune. If that's the case, a FP red might get you close to your goals. AMS used to have a few videos linked on thier site to a car that ran hillclimbs in Europe with an AMS 35r turbo kit.

I'm not really able to give any recomendations on bigger turbos yet as I've never driven an Evo with anything larger than an FP White. I can confirm that I'll be running a "non stock frame" turbo on the car for 2009. Plenty more details in 3 or 4 weeks.

For what you're looking to do, I think you should go beyond a stock frame turbo. Reason being? It's got a dinky turbine housing that causes lots of backpressure and puts a LOT of stress on the engine.

I'd step up to a GT35 if you're looking for that kind of power. You should see a lot less backpressure in the exhaust manifold, which should equal less strain on the engine, lower EGTs, better VE, and better reliability.

 

Both the BBK Full and FP Red will get him there power wise on a 2.0 motor with supporting mods (cams, tubular exhaust manifolds (or a Wilson Manifolds intake manifold), FMIC, IC piping, etc...). On C12/C16 it would be no problem.

I've found that the BBK Full spools about 750 rpm faster than a Red and can hold 30 psi easy to 8k. The only advantage the Red has is that it can make a little more boost compared to the Full. The one issue I've had and others have had with the new Red is oil starvation from FP stuffing too big of internals in the turbo. A possible fix may be finding a new oil feed location but, I've honestly haven't tried that yet.

 

As mentioned already though, elevation will play a big role in ultimate power figures. It all depends on how serious of a hill climber the car will be (Pikes Peak or a smaller regional hill).

 

Like everyone else said the BBK full or FP red will give you quick spool your looking for and the power you want on e85 or meth inj .

 

I could imagine that a 50 trim turbo setup along with a red would get you there! I made 500 whp with a 50 trim turbo on pump gas and meth. Great response with the turbo as well. I would follow dave's advise with the turbo setup. I have watched a few of his video's and they are crazy!

Are you doing a stroker motor or staying with a 2.0?

What tracks do you plan on racing?

 

Guys, he's in Cyprus. E85 is an American fallacy and it's a bad substitute for race fuel.

Will you be using a restrictor? Forget these bolt on turbos if you want to make that kind of power you will want something else.

GT35r or a TR30r with a properly sized compressor/turbine combination. and.. will you be using anti-lag?

 

35R with anti lag if we're talking real deal race car, and by all means a TR30 if you have the $ and can find one.

Bimmu is definately on the right suggestion track.

 

The problem is that the 35 won't handle antilag so it's either that without or the other one...with.

 

30R+ stroker, FPred.

We also need to know about a restrictor. That will change everything, including power plans.

 

I tried searching for a dynoplot of a 2.0L, full-boltons, BBK doing 550 WHP on strict racegas, but I couldn't turn anything up. Perhaps you've got a dynochart on hand, which you could post up for us. Don't get me wrong, it's not that I totally doubt that the BBK could get him to that level of power. However, it would certainly be a notable achievement. Show me the BBK-Full, 550 WHP chart, done on 100% gasoline and Sparky will eat his hat.( I doubt that it will be on CBRD's own dyno either).

 

There is no way no how the Full can reach the Red's numbers,the bbk is good for up to 500bhp no more,so if sticking with a std internals engine he should go bbk,if he is forging it then he should go 2.3L stroker and Red,period.

He is up for a hillclimb,so peak power is not as important as is gearchange transient response or part throttle response and spool up!
