Testing a Fast 90 or LS6 vs Victor with FI
Testing a Fast 90 or LS6 vs Victor with FI Has anyone done a dyno with a LS6 or Fast 90 FI setup against a Victor?
Any before and after numbers? I've serached the dyno section and the FI section and come up with nada. I know the benefits of the Victor vs the others... but what were the numbers?
Thanks to anyone who can share experience!
Also was there a drop in IAT's (or any way to measure it)?

All the info I have read says that up to 10-12bls of boost not a lot of difference in any, but as the boost rises 15+ lbs the Victor jr starts to shine. Most of the info I've seen has been in magazines. There was a guy here on the board that did back to back pulls with a LS6 and a Fast 90/90 set up and he lost @20rwhp and 18lbs of tq with the Fast, but that was with only 8-10 lbs of boost that was a while back when they first cam out I don't know the exact details of his set up I am just passing on what little info I have read and definatly not from personal experience as of yet.
408ci T88
LS6 against Victor at 14lbs
The victor runs alot smoother under boost,Intake temps dropped 25+ degree's,gained 60hp/60tq in the midrange,pretty much the same peak #'s because the Turbo held the same boost level. A Supercharged car will probly make more HP due to boost increase.

Regardless, it sounds like the way to go for FI. 60/60 is pretty damn impressive in the mid range (like it needed it!), what happened on the bottom end? I assume there was a little drop? Any down sides to going this route?
BTW, how tall is this intake w/o the elbow compared to say an LS6? How much of a bump in the hood would you need to fit this thing in a C5?
Thanks again Don for your input!
well its documented that the victor intake is supposed to help with the dreaded number 7 an 8 pistons so who knows...but both days where in the 40-50's and nothin changed.
And in all honesty, i didnt notice anything different down low...i did notice it comes in alot smooth and also the boost was instant in 3rd gear...actually too quick as it surprised the **** out of me.

I'd think there would be a small hit down low, but who really cares about that? What does surprise me is that you really didn't gain much on the top end... I expected there would be a little bumb in the mid range power, but I expected to see most of the benefit above 5500 rpm.
Would you guys mind posting a couple dyno charts to compare the two (assuming no other changes were made and they were run with comparable tunes)? I'm sure people would like to see these results going forward.
Thanks again guys!

i dont have the graphs, dont really care since its not even tuned with the 2 bar thats going in next week or so. Its going for 16psi for street tune, if Don actually has the graphs then its up to him. I dont care what its doing right now to tell the truth since its not the final setup

Why would the boost increase ? Surely if the manifold is free-er flowing the boost would drop ??
Or do you mean if you re-pullied for same boost as Lsx intake it would make more power ?

With the 408 motor there was no hit at all.Maybe a smaller ci will see it.But the 4.8L I just put one on feels just as strong as the stock truck intake down low
We very rarely print out Mike's runs.No reason too since we keep changing things
