JHM tuning

Is the server still down?
What is going on?

Wait till tomorrow and call.

Lol. I’m supposed to be enjoy the power. I’m about to be where ur at lol

Oh man don’t go there. It looks ugly and I have a puddle under the car.

Lol. I just installed the supercharger myself. Just have to wait til tomorrow for the tune. It was a pain lol.

Ah that must be excruciating

Like u wouldn’t believe. Haha.

What were the painful points during installation?

Oh - and PICS!

Welcome to the club. I know that you enjoy it when it is all sorted out. JHM should be open now since it is 9:31 AM PST.

What other mods do you have?

x2? Just curious what you found most difficult etc. I had mine on and off 4 or 5 times. But JHM did the initial install with me. A lot more work to do on the initial install than removing/re-installing.

Headers, JHM manifold, JHM clutch and flywheel.
Everything besides the 4:1 diff and 034 maf hose

The cutting was brutal but I think the worse was putting the alternator back on. Took me like 2 hours with a lot of kicking.
Only got one with it installed. I didn’t take pics of the cutting.
My whole body hurts right now. It was a pain doing the work on the ground.

sexy pics… free tip…your going to want to connect that one hose to the outlet of the supercharger that goes to teh throttle body… more pics or this is fake

Cool. Skip the 034 hose. It was an absolute pain in the ass with the blower. If I could have found my OEM hose I would of had it on long long ago. Didn’t find until after clearing out parts and the car was sold.

Uh oh, somebody has been keeping a secret!
Cutting?

How come? What exactly was an issue with it?

OH NO HE CHOPPED HIS CHASSIS IN HALF!!!

The 034 is great for NA as it has smooth walls, a little larger I.D. possibly, and nice bends. However, the stock TB has no lip, and the 034 unit has no lip. It’s a thiner more flexible piece of rubber/silicone, and it’s more “slippery” on the inside. So under boost and hard shifts, I would constantly blow the seal at the TB. I even had T-Bolt clamps tightened down as far as they could go (if I tightened anymore, the t-bolt would actually push the 034 intake hose off of the TB due to the pressure and it’s slick inside).

JMH’s tune on the stock motors also had the TB shutting down after 6k or so. So at 7k, you’ve got the TB closed a significant portion, and then you make a hard shift and it closes even more and you’ve just made a big pressure block right at the TB. Before the DV could push it all back to the intake side, the 034 piece would blow off and then you’re car dies b/c the tuning was smart enough and restrictive enough not to let it run with the massive air leak.

The stock unit is much more rigid, thicker material, and not as slippery. So it works fine. Also, with the S/C, you’re not really concerned with the air flow intake being really nice and smooth like you would be NA, b/c the blower is going to cram it all in there one way or another. Same reason why dollar to performance, the Intake manifold isn’t the best bang for your buck with s/c stg1 as it is with the NA cars. Probably a bit more gains with the stg3 cars though. (at least thats my opinion on the IM + Blower, no logs to prove that theory)
