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.

I'm really trust in Ivey so i dont think he didnt try. And to say he didnt know how, is just at least weird to me.

What you do have to worry about is the cylinders, making sure they can hold up to the boost your running timing etc. Anybody agree with me or am i missing something?
