You are correct, the entire build must be cohesive. I'm assuming that person was lacking downpipes, an adequate exhaust system, or a proper tune. Heck, I was well north of that before I ever added the Cosworth plenum or heat wrapping.

With the Greddy TD05-18G's, I reached 609 whp on 93 octane at 17.5 psi on Japtrix's Mustang dyno. Roger at Japtrix told me that that particular dyno reads about 10% lower than a DJ. Moreover, I think Alberto reached 665 whp with his TD05-18G's using pump gas on a DJ.

My point is that it was weak to use Sam's own marketing hype as a response to Tyler (thawk408). For years now, Sam has been rating and/or recommending some of his GTM parts for power levels that his parts have never been successfully tested to, either by himself or in the field by end users. Sam is doing the same with his turbo kit now too. In comparison, PowerLab tested their kit with the GT35R to 654whp, and then tested with the GT37R to 706whp and the 76S to 906whp before they made the 35R kit available for sale to the public and BEFORE they made any performance claims to promote their kit. IMO Sam and companies in general shouldn't rate or promote a product for X horsepower if that product has never been successfully tested at X horsepower. It's BS to sell and promote a product that hasn't been fully R&D'ed or tested to its maximum power capability and expect customers to be the guinea pigs.

As for Mike's build... It's not the way I would have chosen to achieve 1000+whp, but I respect and support Mike as a friend and therefore hope for the best for his project. He has chosen to go with unproven components that thus far have not been used for a 1000whp VQ build; particularly a 4.0L non-sleeved block and cast log style exhaust manifolds. I have concerns about the longevity of the thinner than stock sleeves (due to 97mm bore) of the 4.0L non-sleeved block and it's ability to sustain over 800whp under load. I have posted my concerns publicly and have discussed it with Mike privately. I also wonder whether the log style manifolds will flow well enough for 1000whp. I anxiously await the results of Mike's build, since he is going into uncharted territories with those components.

I respect Mike for pushing the envelope into uncharted territories, since I am also going into uncharted territories with my build by attempting to push the 5AT trans farther than anyone elso has pushed it before. I therefore appreciate the risk Mike is taking for the sake of the community and its knowledge base.

I don't put too much stock into particular hp #s compared across dynos. Variability in tune, dyno measurements and temperature differentials can easily account for such differences across similar builds.

Now I am really wondering about this build. I did a quick search through the recent threads and didn't see it. Do you have a link?

I agree. If Mike doesn't make his goals, it will be because of the log style manifolds. More specifically, reversion issues. As you said, I hope they flow well enough to not hold him back. I have the same manifolds, so I have my fingers crossed.

This is another very valid concern.

nope, its a full on solid build done at forged. 3" downpipes, cosworth manifold, jwt c2 cams, 1000cc plus dual pump.

guy lives in TX, so not at altititude. Its still makes alot of useable power, just there was a huge amount of money spent overbuilding that car for the dyno it made. Prolly could saved close to 2 grand and shoulda been able to run the same power.

Sharif tuned it, so I trust the tune. I'll bet if someone asks Sharif about the low hp on c16, he'll have an answer. There is something going on that we don't know about.

On my build, Roger at Japtrix commented on how easy the power came on. He only stopped at 600 whp because that is the target I set. He felt that if he pushed it to the limit, there was another 30 hp left on 93 octane, but I did not want to be right at the edge.

Before I over-reved my motor, it was laying down a lot of power. My Toyo R888 305/19/30 tires were spinning when the turbos spooled up in 3rd gear. Imagine starting at 2k rpm in third 3rd, and then once you get to about 4000 rpm (around 50 mph), the rear tires break loose. It was crazy power.

That is why I am going with a longer duration cam on the new build. A little less torque at 4000 rpm, but more top end power.

Feel free to call Roger at Japtrix and ask him about my build. He will tell you, and this guy has built/tuned alot of VQ motors.

sorry, i was in cairo just came back today

ill post the pics today
