i think the best sc for the hr would be the rotrex like the hks for the new jackson racing (or kraftwerks or whatever they're calling themselves now). they run the coolest and have the best efficiency at over 90%. that'd be the only supercharger i'd consider getting my my z...

 

Haha, i completely missed this thread. I would still love to do the HR Vortech combo. If you are serious, we could definitely do it for the HR. Give me a call at the shop.

 

I think everyone knows company's like Forged, GTM, and AAM are capable of doing a one off supercharger on an HR but I think what people here are looking for is a production supercharger kit.

 

New HKS blower that isn't durability tested yet FTW. Blower should be out sooner or later and apparently destroys the C38-81. That means Rotrex started on a bigger blower to compete .... yay competition.

 

why would anyone want a supercharger? lol

 

track junkies?

 

^+1, although i'm not a track junkie yet, but i plan to be one as soon as i get my bbk (hopefully within a month or 2)


hks basically copied rotrex on the blower design. i know there are some minor differences, but its pretty much the same thing. its like the difference between a vortech and a procharger.

i wasn't really refering to the exact brand of supercharger i'd like to see, but more the type...

 

Its much bigger than anything rotrex has in terms of CFM/boost output, without a huge increase in physical size, all I know about it really.

My buddy's M3 should have it soon, assuming no more hold ups occur.

 

i was under the impression rotrex had superchargers to support 800+whp... could be wrong though.

anyway, i'm interested to see what this "big" blower is capable of, can you pm me with results (or link if it will posted on the internet anywhere) when its done? thanks

 

C38-81 is capable of ~630, I have a friend with 505 wheel on AA's mustang dyno with that on an E46 M3. E90 M3 should be much more impressive with the HKS (the C38 couldn't push enough alone).

 

I would still prefer turbo.. doesn't mean they have to be HUGE a push out 800 whp.. lol but i feel you Nexx!

 

its not a matter of being a track junkie. its not wanting to spend 10k to turbo your car. then spend another 10k to have the motor built.

 

Being on a track a centrifugal is just much easier to drive with, a turbo is faster if you can control the car, but given our power levels with turbo, it would take quite a setup tire and suspension wise to keep the rear end pinned...

 

HEHE Drift.......

 

if i've learned anything.. its best to stay N/A than be FI on a budget
.. **** never goes right and when you run into problems.. you are left with a car that you can't fix.. if you can't spend the money to do it right.. don't spend it at all..

FYI from what we have learned from DE Motors.. SC have blown more stock motors than Turbo's.. so if you're hopeing reliablity will be on your side.. guess again

 

thats because SuperChargers have no TQ.. and if you can't control your car.. what the hell you doing on a track anyway? i would rather take small turbo's that spool fast and have that TQ down the straight than run an SC..

besides.. that whole SC power on tap is a myth... we had a side by side comparison of a GreddyTT vs Vortech.. and once the GreddyTT hit 3000 RPMS it was a wrap

 

thats why we're (well at least me and peak350) are hoping for the hks or a rotrex, they actually make torque. look at some of the hks builds from gtm on the de's, they make much better torque than the vortech. still prolly not as good as nice quick spooling tt kit, but its cheaper. and just cause you can save a few g's with an sc over a tt, doesn't exactly mean you're cutting corners...

 

not cutting corners... counting pennies.. if he is counting pennies now.. its not a good idea to go through with the full deal

 

just cause he's stingy doesn't mean he doesn't have more than enough money to go fi...

 

says he doesn't want to spend the motor to get a built motor if you don't want to spend the money or forsee spending money to get a built motor.. then don't go FI
