I can't link it because the GTM site is Flash based, but it's toward the bottom of the supercharger kits page. It's called the Stage 5 Tuner kit and it's $5600.

Yeah it looks like basically a Stage 3 package with no fuel. I'm assuming the unit is modified to the same specs regardless of what "Stage" it is, right? So yes that would make the Stage 1 make more sense.

Also, I thought I read somewhere in this thread about your exhaust setups and that free flowing isn't always the best?

I'm thinking of either running my HKS dual with test pipes or my JIC full ti with test pipes. So would I lose more boost with the JIC than the HKS hypothetically?

It's hard to say as there does not seem to be much consistency in the numbers. My opinion would be that there would not be too much difference b/w those 2 exhausts, however the test pipes might cause you to lose psi and possibly a small amount of power vs. HFC.

Earlier in this thread, Itozann said he lost ~2psi and 10whp by switching to test pipes.

I'd be interested to see what Motordyne ART pipes do tho.

YEAH, after I installed resonated TP's, I lost about ~2psi and about 10whp.

I took my Berk HFC's off an put the stock Cats back on. I gained 2 PSI. After doing so reading, seems that Superchargers like some Back pressure. The deal is to find the right amount Back pressure for both Tq and HP.

psi does not = horsepower

psi is a measure of air flow resistance. so OF COURSE you gained psi by putting the stock cats back on....

Itozann, you did a retune after adding the test pipes?

cdoxp800

iTrader: (12)

Correct, but I also gained 20ftlbs of Tq.. So like i said earlier.

+1

That was definitely the case with my Vortech...I got more power with a Moordyne xyz+hfc that with just straight TP's...

ITOzann

iTrader: (30)

yes I did retune it right after the tp installation. I change the set up from oem cats with a single exhaust to resonated tp's with a true dual exhaust. Anyways, I agree with cdoxp800. It seems that the HKS s/c likes back pressure.

BTW, has anyone dyno'ed in a low calibrated mustang dyno. I'm not trying to compare gains or anything like that. I just want to check the output.

Yep. I read your post and also talked to Tony. Very good info and nice improvement.

so does this kit(rotrex) sound like more of a turbo? does it have that wind like a traditional roots type? never heard one before. plus i love the sound of a turbo, but if i can get it with the reliablity of a supercharger, its a win win

There are some videos in this thread and there are some on YouTube.

Either way I would not purchase any forced induction kit based on the sound it makes.

Please don't choose an FI system base on the sound.

I can't find a 7pk1060 belt. I'm looking for one. Mitsuboshi makes one, but I can't find anywhere to buy it. HKS makes one, but they want an arm and a leg for it...

For the ATI crank pulley and the HKS SC, sizes should be
6pk1735 or 6pk1740 for alternator/ps
4pk860 or 4pk865 for a/c

^ What is your current configuration Jonny? You sold your ATI right?

Hey ITOzann, do you have any of your dyno sheets you could post? I thought you posted them once, but I couldn't find them...

ITOzann

iTrader: (30)

I only had a pic of the pulls at 6psi but and print outs at 8psi and 10psi.(all done in a low calibrated mustang dyno) Hopefully I still have them around since recently I moved and threw/lost lots of stuffs

Bummer. Let me know if you find them for sure!

Hey guys been a while since I posted in here do to some projects I have been working.
So take I talked with Sam about a few of my ideas and he cannot see any issues with them.

1. I plan to relocate the MAF out of the HKS Suction Pipe (Currently using PMAS Here) and moving it up by the throttle body and using the OEM MAF (New 3" section added to existing Pipe). By doing this the ECU will see a truer air intake Temp and less turbulent air. This will let me run my OEM MAF. The current location of the MAF is seeing allot of Hot air from the engine Bay and passes this to the ECU, but the true temp of the Air after the intercooler is much cooler and not being take advantage of in the tuning.
See below Pic:


2. I plan on building a New Intake for the SC itself to get a way from the garbage HKS filter and moving it to a cooler air location. I plan on using a Apexi filter (Part #: 500-A024). I chose this filter because if this review.

I feel all these changes will help better the performance of the HKS kit. It's going to take few weeks to get all this made because of work, and then a whole re-tune.

AWESOME!!! if you would consider doing an extra intake pipe let me know, I'll put a deposit on it I tried 6 different filters and none worked with my large aftermarket radiator.

Please let me know

BTW, where did you get that pic from?
