Aluminum intake manifold
-
-
I thought I had read someplace that the plastic manifold was limited to around 18 lbs boost and any higher required a metal manifold. I thought rabtech had made the switch with his latest big turbo.
No I am pretty sure he is still running the stock manifold. I think the main reason for going to an aluminum manifold is simply that they can be hand fabricated at much lower cost than tooling to make a plastic one.

I think it has something to do with what this guy says. He was a genius above my comprehension.

rabtech is definitely still on the stock plastic intake manifold. We took a stock plastic one and plugged off all the openings with some metal plates and did not have an issue with it starting to leak until over 40 psi of pressure. We have been in the upper 20's for boost pressure now on our engine with the stock manifold also.

I’ve been running 26psi for quite some time with zero issues from the plastic intake manifold.

I stand corrected!

Im learning from reading this thread along with other threads & if theres one thing ive learned so far is, To not sit in any BOOSTED slingshot, it might hurt my pocket .........

I swore I was going to keep mine stock - that was until I met rabtech in Florida. We talked about boosting and I told him no not me. Then he said come on lets go for a ride. Ordered my first Turbo the next day.

MADDMOE I think the take-away from MACAWS post above is his use of the word "first" as in "first Turbo." Like you, I will not be taking a ride in a boosted machine for some time to come.

This is why I do need to go to any of these rallies I don't need to be seeing any of these mods. I am totally happy, for right now, with stock. Even if I wanted a turbo I have no one to install it. Don't think it is something you would ask your dealer to do and I don't expect any of the local have even looked under a hood of a Slingshot. Besides most of the roads around here are 45 and 55mph and I get up to speed fast enough. Please never offer me a ride in your turbo.

confirm I am on my third turbo!
Speed and HP are an addiction - but still cheaper than women

I am putting my stock manifold back on, but have a question. When I installed my supercharger, I plumbed the vacuum line for the BOV to the port below the throttle body. I also used a "T" fitting on this line and hooked up my boost gauge.
I have installed the EVAP purge solenoid bypass, for which there is a cap for the port above the throttle body. Can I use this port for my BOV? I want to clean up my install and eliminate the "T".

Agreed, all the more reason I'll look at your ride during Uncorked, but there is no way I'll be going anywhere with you in it. Like you, I'll then feel the need to "invest" in a Turbo.

Come on go for a ride - I will pay for the gas

I'll test out your seats, as that's my next upgrade, but a Turbo is going to require some serious time behind the wheel before I make that jump. Perhaps after Maggie, we'll see. Thanks though for the offer.

WAY WAY WAY WAY WAY cheaper than a woman smdh.......

OK speaking strictly as a novice here I hear all this talk about being boosted and turbos...at the end of the day how do you get all that power to grip at the rear wheel? Are you lowering tire pressure? The slingshot is so light I can’t imagine how all that power can be usable or is it just finesse in how you use it? Inquiring minds would love to know🙂

Extra-sticky tires help, but I'm too cheap to buy them. It's bad enough paying for a Nitto 555 G2 315/35ZR17 at around $250 mounted, let alone paying a lot more for an extra-sticky tire. I find trying to accelerate as quickly as possible while trying to minimize rear wheel spin to be part of the fun of the Slingshot.

Soooo exuberance coupled with finesse 😏
