NEW! StreetRace Billet Intake Manifold from Hahn RaceCraft!

Quote from lrobbi

Any Dyno numbers for forced induction (Turbo or SC)... this manifold vs. plastic stock?

At this time, we've yet to do a back-to-back comparison on a boosted Slingshot application to show a before/after result. On other Ecotec applications, we've seen a 10 to 20 HP gain boosted, with a concurrent smoothing out of midrange torque due to the shorter runners, which helps to improve traction on the traction-limited Slingshot.

Here is a dyno graph from Greg Hartman's Slingshot that we just completed. While it's not a before/after, it helps to show how the manifold really assists the upper RPM range, with usable power all the way to 6800RPM:

@Bill from Hahn RaceCraft what's expected turn around on the intake manifold.if I order today how long before I could see it

Currently, we're about 3-4 weeks. That will improve as this new product reaches full production, and as we shake off the effects of Hurricane Irma.

on the fence right now between this one and fab factory's intake manifold gonna go with whoever can get it to me fastest

I understand that for sure! Mind if I ask how we compare on price?

I am just wondering if the Alpha CAI can be adapted to the Street Race Manifold or do we have to order the the Cool Ram Intake and the Air Box? I will be making up my mind on this as soon as I get my SS back from repairs in the next week or so.

From what I can see so far, I'd think the Alpha pipe could be trimmed shorter and the Alpha intake be thus compatible, but I should emphasize that is just an educated guess at this time. With any luck we will soon have the opportunity to see this in practice and learn the feasibility!

One suggestion: you could ship us your Alpha airbox assy. and tube, and we could investigate it here.

I was just wondering if you had already checked. This something that I can do after I get the Manifold. I knew that the question was going to come up after the parts were available.

I'm confident we will know soon. Thank you for your strong interest!

If you decide to go ahead and investigate this on your own, please let us know what you find, and we'll kick you back a credit for your efforts.

@Bill from Hahn RaceCraft sorry just noticed your responses price wise I’m not to sure because I’m still waiting to hear back from fab factory they had called me but thought I was in the market for an intake manifold for a bmw. I believe their online price is 1400.00 if you could produce one before them I’ll send over my information but as of now nothing yet. Ok goin to be finishing up some tuning soon on a stand-alone and I want a better manifold. So still very interested hopefully they will be available soon. Gloss black to be precise. Also if u did it in black will the Hahn logo be in white ?

We are in stock as of this coming week, @jluna317, and it would look DYNAMITE in Gloss Black. Sooner you place the order, sooner we can get it off to powder coating, which takes about a week. Yes, a white logo would be perfect, we'll do just that! If you move fast, we can ship you from this current run.

Bill, when can we order and expect delivery of the Manifold?

We've been busy. We've been very, very busy

Shipping starts this week, have a couple in this run that aren't already spoken for, so now's the chance!

Quote from FunCycle

Thanks @Bill from Hahn RaceCraft, maybe mine is in that bunch #1782

Indeed it is! While it will look like the one all the way to the right, it will actually be one of the others, some of which leave for powder coating tomorrow. Usually that's about a week of turnover time, then off to you it goes!

We will begin shipping this week. One can place their order anytime by clicking here.

We have a couple left in this run pictured above which are not yet accounted for, and are now in constant production so as to meet demand, so we are looking good going forward!
