Um... not sure I understand what you're getting at here.

I wasn't bashing... just stating a fact that it doesn't matter how much hp you have if the torque isn't there it doesn't matter... with that said the RX products have been proven to be great so I'm sure that's why the bar has been set so high.

I kinda of agree with you on torque - bu the reverse is also true. I had a 455 making 380ft and an amazing 185 hp. Slow as smoke in a calm june eveaning.

How do you gte access to a 1/4 mile track and not have the timing system active? Seems very cludgy to me.

.... Ya, I think RX products does great work also. But i will bet, you get almost identical numbers from theirs.

My point is any centrifical pump, is not going to compare to a screw drive blower. I can see why your torque is lower. Once its pushed as much air down that throat as it can, it doesn't keep ramming it, like a PD pump.

If you understood the mechanics of both, you would get what I'm saying. The thing about working in a refinery, is you play with these things all day long.

maybe he means why bring up positive displacement superchargers when:

A) this thread is about the IPF centrifugal

and

B) There is currently no PD superchargers even in the works for the LLT, let alone available...

so why bring it up in this thread...

from the youtube description:


Thanks to our friends at Firebird International Raceway for letting up on the track for a couple hours.

Sound like they just let out on the track to makes some passes, without dragging all the timing equipment out... so freebie vs a full blown track rental... ???

Sucks Big Time! And they look better

Because they were talking about the torque. Common knowledge is centrifical SC doesn't build torque like twin screwed. You want torque? You want positive displacement.

it looks like if the race was any longer that V6 would have lost

This is why!

Impossible to really tell anything from this video....

Looking at the beginning of the video and see how much the V6 is ahead at the start:



IMHO... Either the V6 jumped or the SS was asleep or spun badly off the line... You can hear some tires squealing in the background.. Since we can't see both cars launch or a time slip we can't really tell...

Watching the video of my run at Atco against ROD1, I beat him at the tree by .28 and was out in front the WHOLE 1/4 mile and went through the traps first... But the fact is Rod ran a 13.4 to my 13.6 and trapped almost 3 MPH faster than me! If you watch the Video it almost looks like this V6 vs SS match up:




The big question is of course what was the ETs? I have seen stock SSs run high 12s/low 13s all the way to low 14s... there is simply know way of knowing without timeslips!

But it's not an option... so if you want instant torque put in N20... next best thing would be turbos..

Alright. Went back and reread it. I thought it was refering to the low torque numbers with the high rwhp. I was explaining why that would happen. They were talking about the rwhp of the SS being lower.
