You guys have to check this one out. I'll tell you what, if he is making that kind of RWHP @15PSI and on pump gas too, well, then I need to go back to the drawing board! Damn. I know it's just peak numbers he says, and that we don't know how the curves look, but still. Check it out. He is kind of confusing too. He expresses the power in HP in the beginning, but at the end he states it in RWHP. Kind of inconsistent in that respect. But if it is RWHP, oh boy, that's alot of power at that low of boost.

i was just about to post this one...that's a little unbelievable for rwhp at 15psi. not to mention autothority chips/maf with 55lb injectors. another bull****ter rides...

RolexNJ

shaheed: Sorry I beat you to it pal. But damn, "if" it's true, I'm in a world of trouble with my 3.0L 8V!

I just sent the seller a question asking him if it's in HP or RWHP and if he has dyno charts too to back it all up. I'll keep you posted.

shaheed

he has a dyno chart towards the end of the ad that shows 401rwhp, so i'm guessing he means 465 flywheel. i'm still not buying the whole story without some more evidence though..

RolexNJ

I agree, but, we shall see if he emails me back; and with charts too!

That dyno chart is the exact same as TonyG's!!

The intercooler pipes are stock and the intake doesn't look like it's a MAF at all. MAF don't work with stock intercooler pipes.

Agreed. Explain that to my MAF and intercooler pipes

Anyways its clear its 465 at the crank. He's pretty straight forward about it and the dyno chart posted is 401 rwhp. Where's the confusion coming from exacty?

its 400rwhp and 465 at the crank

When you were talking 465rwhp at 15psi I was doubting him, but I'd think 401hp is possible. His mods are very similar to what I'm doing (except the stupidly over lightened crank '16lbs'!! I though 10lbs was the agreed practical maximum for our cars??). Also surely the only peice of piping you need to change is the section from the MAF to the turbo? I intend to use standard intercooler pipes with a 60-1 turbo on my car, and 55lb/hr injectors.

oh btw I still think 400rwhp is bs. lol.

A 60-1 with 55's aint gonna do it. At least not at that boost pressure and pump fuel.

DivineE

Are you doubting the potential of those parts?! Well when I get my car finished I'll post the graphs and give you an honest comparison. Ok so maybe I agree not at 15psi but I think on pump fuel its possible. The turbo (if its like the lindsey one I have) has a maximum capacity to run 610hp @ 15psi, or 899CFM @ 15psi (if you trust their figures which I do) so should have ample capacity. Then on the post about Rolex's car someone calculated that the maximum working capacity of 55lb/hr injectors should be about 450rwhp, and there was a car here in the UK which ran 422hp at the crank with 55lb/hr injectors and according to the owner there was still capacity to spare. So I believe it is possible. Whether this car runs that hp is another matter.

RolexNJ just proved that with 55lbs injectors, 461whp is very do-able. Yes, injectors were probably running 90%, but do-able.

The 60-1 HiFi can flow 1200+CFM, and 66lbs/hr+ easily supports 650+hp (flywheel), you just need an engine that could make such power (which is another story). The 60-1HiFi is a monster flowing, low boost turbocharger (doesn't like 21+psi boost, works very well with 10-20psi or so).

porshhhh951

Maybe I am wrong but, didnt he just say 60-1 hifi. A 60-1 hifi which some of my friends run wouldnt get you there. And the fuel argument has been done. I dont know what fuel pressure he is running but, I bet it aint that safe. If your going for big hp why not by properly sized injectors. I guess I am wrong but, I thought the hifi was the small turbo. The 60-1 is the big brother. I promise you the 60-1 hifi's on my friends cars couldnt run 1200 cfm. So hos maybe your #'s are off or maybe we are talking different turbos. Chris runs a hifi with a t3. Now ofcourse you can swap out the turbine but, 1200 cfm.... eh.

Also I have never been a fan of authority or believed in their tunning. This guy seems to though. I dont wish to debate over some car on the net. If he is pushing that hp it aint safe with 55's. Not in my mind.

The turbo may be a 60-1. That would explain the cfm flow difference. Divine I believe very well in flow #'s posted by dave. Their 75 was way up there on cfm...in the 800's somewhere.

Tuning matters alot ofcourse still 400rwhp on 15psi and pump fuel isint a small feat or easily acomplished. I will have to go back and take a look at the dyno chart...I wonder if it was a dynojet or not.

Anyways I would like to know. I thought the hifi was the small brother of the two. Some clarification on this would be good.
