That is correct.. Its safe to assume I am aware the evo was never a drag race car... Luckily though the 4g63 motor is the best 4cyl platform in my opinion and will be hard to top.. Just like the supra which once again was not a drag race car but the motor is one of the baddest lb for lb import motors ever.. Come to think of it cant really think of any import car that was actually designed for drag racing, can you?? you think the 170hp B16 was designed to drag race at 1000+whp?? None are DESIGNED for drag racing its just what we do with them..

"stronger internals but weaker block...kinda defeats the purpose imo. "

how do you know its weaker?
Because its aluminum?
So the plastic should be a weakest no? Well i personally saw a plastic gun, and i'm telling you it is good enough to shoot a bullet to kill you
The question is what is the weak means? If its good enough is not enough?

How many 1000 whp evo are on the street? And how long?

 

besides 98% of the people lookng for easy whp. And most of them will never going over 450 whp. It is just a fact, in the EVo history.

SO the question is which engine is going easier up there and cheaper?

 

I like the peace of mind knowing that if it can handle 1200whp then when i make 800whp i wont have any problems..

If history proves itself to be true with this 4b11 there will be issues just like the sleeved honda blocks.. There is nothing more frustrating to me then a shifted, twisted, warped block.. If you overheat it the sleeves distort.. the same cannot be said for the cast iron block from my experience.. Again well just have to wait and see how it goes.. I am not very optimistic myself..

 

you are the member of the very small procentage of the evo owners whos goal is over 600 whp.
I dont think mitsubishi designed any car to please that very small percentage.
Fact is the most evo's in racing running less the 600 whp. In the rally they around 300-400 whp. So for the 90% of the racing the 4B11 is more then awesome.
Not to mention the rally the 4B11 is a blessing, no need to open the engine to get a 400whp and under whp. Which was not realistic with the 4g63 by rally rules.
So the 4b11 is on street/ emission/ and racing /exclude drag/ is do amazing job, almost unparalleled
in racing.

So if its not please the drag racer, be it.
I rather go this way then the opposite.

 

IMO Mike is right on this one. We will see what happens but i think there will be some problems which will be worked out eventually as time goes on. Its funny how people are so against a aluminum rod but think rules dont apply to a aluminum block?

But as more is coming out i think the cylinder head might be the restriction. Like it was talked about losing the 1.7 rockers kind of put a bind on the cylinder head. Will the cylinder flow more? Yea i think it will but the problem is going to be the cam profiles you will be able to use to try and use that flow. We shall see i guess.

I am going to say a few things, don't take any of this as me being a dick to any one singled out person in this thread. Just making some points.

First off, I've been hearing "DSM's/EVO's are drag cars" for 20 years now. The first pass I made in a DSM was a 15.11 second pass. Some guy told me, "That's not drag car." Well the fact of the matter was it was faster stock than my 1985 Monte Carlo SS with a posi-traction solid axle 3.42 gear ratio, which some considered a "drag car". It was also faster than the 5.0 Mustangs of the day with their solid axles and many did consider then "drag cars". The only cars that were ever "drag cars" were the factory lightweight cars of the '60's. So saying the "DSM or EVO" aren't drag cars is just a statement that is a waste of breath or typing to anyone who has ever said it. The DSM has gone 7's in AWD form, thank you John Shepherd. The EVO has gone 8's in AWD form in quite a few people's hands now. My personal RS has gone 9.0's with a 100% stock, yes you read correctly driveline other than a clutch upgrade. If that's not well suited for a "drag car" I don't know what is.

Aluminum blocks, Top Fuel dragsters use aluminum blocks. I don't think any of us can judge the aluminum block in the EVO. First off, Mitsubishi and Honda, not comparable in many ways. First of all Honda has never built a factory turbo charged performance car that I know of. Mitsubishi, I am fairly certain, didn't build us a week platform. As easily as our EVO X just made 407 on our dyno I don't see us having a problem making 500. I'm also guessing it will hold up quite well, as Mike said, only time will tell.

As for the head, we've already flow benched the head, the head flows very good right in stock form.

The mildest Cosworth cam made just gained 40 whp on our EVO, I don't see where making power without a rocker arm ratio of 1.7 is going to be a problem. The HKS 272 cams were good for about 25 whp in the 4G63, that ratio didn't seem to help much there.

I don't think there is a better 4 cylinder than the 4G63. Will I end up changing my mind? From the looks of our recent results on the 4b11T, there's a chance of it.

I also don't agree that there is a very small percentage of EVO owners who goal is over 450 hp.

The EVO X is heavy and for anyone going from an EVO8/9, it doesn't have the feeling of the EVO8/9. The EVO8-9 feels quick with 310 whp on our dyno, good response, feels fast. The EVOX did not have that feeling to me. It felt good but not like the 8-9 did. The EVO X, now that it is making 407 whp feels more like the EVO8-9 did with 100 less whp.

I believe the EVO X is going to have a higher horsepower owner than the 8-9 did, just because the doesn't feel as fast with less power.

I believe you also have to look at how easily the EVO X just made power. A Stage 1-4 EVO8-9 on our dyno, on pump gas and a flash, on a good car, will make 310'ish whp on a good EVO. Add to that the Green turbo or even the Red and you may see 360'ish whp on a good EVO. We have our Stages 1-3, cams, 780 injectors, Blouch 2.0 turbo and a stock fuel pump and just put down 407 at 24 psi. Impressive if you ask me.

I admit, I've been disgusted with our EVO X for quite awhile. Now that we've got some "issues" sorted out and the car is working like an EVO should I believe in the months to come the power we see out of the EVOX is going to grow quickly. I haven't seen much from anyone that's impressed me yet and from what I am seeing right now, the power the EVO X's should be making is a lot less than I see them making.

I'm going to take our car over to the Dynojet this week to put it in line with most of the EVOX numbers I've been seeing, just for comparison.

 

Poopra.

All the other japanese supercars were built with handling in mind, unfortunately the 3000gt and 300zxTT were TANKS. FD's handle.

Dave I hear you and agree to some extent that although it is clear that they were NOT DESIGNED to be used for the 1320, they take very well to it due to the advantages given to us in the form of the AWD system/drivetrain.

What i was getting at is that those 5.0 mustangs and or montecarlos with huge alcohol fed, boosted v8s, and an automatic will leave our lil ricer burners at the lights any day of the week, a well sorted, rear wheel drive, v8, with slicks will embarrass most every evo but the absolute quickest at the strip.

The trade off is, the other guys have to be in VERY fast Porsches/Ferraris/Vettes/BMW's to keep up with these cars with modest power increases on the road course, shows me that this is what they were designed to excel at.

Scorke

 

Yes the RWD Automatic V8's will always be quicker than our cars.. The thing that i have found to be amazing about the evo is that a 9.0 Evo can do more than just drag race.. It can road race, It can Autocross, It can " street Test ", it can drag race all with just a change of tires.. I have yet to run up against any 9 second montecarlo that can road race and drag race with just the swap of tires and be competitive..

 

Not taking anything away from you or your build or your car, but your car would require LOTS of changed to go from running 9's to road course racing with just a tire change.

Scorke

 

Find me a 9.0 montecarlo and swap his wheels and tires to road race tires and ill race him around any road course on my EXACT setup i run and well see who has faster lap times.. Like i said the car could be competitive.. I didnt say i could set lap records with it but i can do more than 1 thing with it.. Not many cars can do that..

 

David, I agree with most all of what you said and think you have some great points. I do, however, disagree that the X needs 100whp to be as fast as a 9, because the numbers at the strip show that it needs a lot less than that to run comparable times (about 30whp seems to even things out).

Perhaps I misinterpreted what you said, and you were talking more about the "feel" than the actual times at the strip and in that case, I guess I see your point because the 4b11 seems to build power in a more linear fashion and doesn't have quite the surge feeling that the 4g63 does. Perhaps this is because of the bore and stroke ratio difference, although I would tend to think that it's more the factory turbo config and tuning characteristics than anything.

In any case, I think you guys are doing great with your X and am very impressed with the results so far. Congrats, and keep up the great work!

 

sti2evox, correct, the "feel" of the car is what I was getting at. At 300 whp our EVO X ran 12.2 at 112 mph. An EVO8-9 with the same power would go into the 11's. The cars just feel different, much of it could very well be attributed to drive by wire in the X.
