it's a buncha supras being dynoed... plus his car on a dyno, and then the video flashes the "max" numbers from a dyno on the screen for a few seconds without showing the actual charts or anything.

I'd sure like to see the charts though, since his listed results are so much higher than those suggested in the past by LMS kit owners... just to insure they're not from a shift spike or some other dyno error (it's a bit trickier to dyno an IS350 auto correctly than, say, a V161 Supra)

If they're posted elsewhere please let me know the link.

Even better would be some sorta base pre-blower # on the same dyno.

You'd wish, but I just don't see it happening. I'd love to be wrong though.
Also, there are headers for our car. I will be guessing it will be anywhere 10-18 WHP according to JBE dyno.
What headers are you talking about? PPE's gained 16rwhp.

Mustang Dyno for sure, you are 100 percent RIGHT about DynoJet, junk to say the least. They float number like it is there job, and I don't like BS. 400 at the crank I would put money on all day long. I beat the car stock and then drove it supercharged, all I can say is "HOLY *HIT!!" what a difference. I'm VERY happy with the improvement. I felt my twin turbo IS F before she was twin turbo'ed and at 5psi that gained over 200hp on that V8. Now, that is NOT comparing apples to apples but this isn't the first supercharged or turbo'ed car I have owned or built. I have built 92 cars since 1997 and this is the 85th one I have done force induction to. When you have all the experience that I do, you can sit behind the wheel of a car and then after forced induction and pretty much call the gain. This isn't rocket science as you know, and I'm sure you could do the same thing to with that experience.

As soon as I get it home from SEMA it is going right on the dyno to dial in this supercharger the way I WANT IT. I can put my money where my mouth is, I don't talk crap and NOT back it up. Look at my work and my work from the past. Like Hogan says, "You know what I'm sayin' brother?"

Thats a new trend I see people on here quoting crank hp. Car looks good and I love the color. I bet it looks better in person. I should change my sig to 500 hp....naaawww. I don't think so.

It is the same overall exhaust, but between left and right mufflers, they are different. The right muffler is straight through.

Look at that review. If you were to tap both mufflers, they would make different noises.

The F-Sport is made that way. The right muffler has a straight pipe going through it ... thus making it louder.

Yeah PPE. I was thinking about my friends 335i tune. Juice box. It is actually 16-21 WHP.

https://www.clublexus.com/forums/per...0-headers.html


go watch the video...367 WHP.. That is more than 400HP to the crank.

https://www.clublexus.com/forums/is-...g-for-fun.html

I highly believe the IS350 on SC can push out way more than 400HP to the crank with PPE headers, improved IC, etc.
