Vortech owners...step in!

[mavrikZ]

Well I just bought a Vortech system. Vortech claims with the aftercooler setup around 450Hp on a non-ram air car and 470hp on a ram air.

That means around 380Rwhp and 415Rwhp, respectively. Is that it?
I have yet to see less than 470 to the rear wheels in sigs.

What do yall dyno?
Im having second thoughts about the system, now...

I thought Vortech rated HP at the rear-wheel?

Why didn't you get the Procharger??

I loved my Vortech, don't listen to Ed.

Ive gotta listen to Ed...this is his "bag baby!"
But I wound up with the Vortech because a buddy of mine was selling it at the right price...I just couldnt justifey spending an extra $3K!!
From what I have seen it looks like their numbers are rear wheel with the kit(470HP claimed), but they list the BASE HP at 320 HP(ram air models...whatever difference THAT is supposed to make.LOL). 320 isnt quite RWHP on these cars...usually. Just want to make sure Ill be getting over 465 to the wheels. Kinda scared me!

My concern is drilling the oil pan. You shouldn't have to cut your hood, but other SS owners do.

Plus I don't like having all the blower on top where heat rises. And you can't get to the engine.

Drilling the pan is not a big deal, they give a reverse drill bit...so nothing goes into the motor. If everything is installed right, and the motor is good...you should never need to get to the motor.

Yeah, when you do need to do something to the motor, it could be a pain.

Werd!!! And the Aftercooler is not as efficient as an intercooled system unless you can pack it with ice after each run...

I beg to differ. There are a few things that can be done to make it work better than stock.

You could add alky injection, which in my case worked extremely well

On the SS hood, I cut the back part to where the cool outside air would flow directly on the aftercooler.

Add water wetter, maybe it works, maybe it does not.


Just adding my 2 cents when I had a Vortech on my 2000 Z-28. Everything I did allowed me to run 27* of timing at WOT.

Stock for stock an air to air intercooler will out perform the aftercooler most of the time. Trust me I have seen it first hand. My budy used to have a Vortech system before he went N2O. His egt's were always higher than mine and had sinmilar set-ups. ATI P-1SC with 7 psi to Vortech G-trim with 7-8 psi and an aftercooler. My egt's were always cooler than his and he had water wetter added to his aftercooler to. My system is the stock twins from ATI. I am by no means downing their system because we made the same amount of power too and his car performed as well if not better on occasion. Heatsoak has always been that systems enemy.

Yes, water wetter works somewhat. Yes, alky works but it also works well for an intercooler as well!

Im happy w/my vortech v-9 after cooled kit. The Vortech kit comes totally complete and with an 8 rib drive system unlike the procharger p1. There is more to the vortech kit but it is not a big deal. My kit with long tubes and 4:10's went 12.70 at 113 mph at a mile high with a slipping a-4. All in all, vortech is a good kit. I would take it over a procharger. It looks better too esp. polished.

Dyno numbers for a base 98 z28, no mods, yes stock, not even a catback or free mod, with a vortech non aftercooled supercharger was 387 rwhp on a dynapak. I saw the numbers and stayed the entire time for the dyno tune. Aftercooled, you'll see between 400-410rwhp

I love my Vortech V9 Gtrim. Happy with performance, setup, appearance and what it provides to the rear wheels.
