You're looking at ~1200 for a cf manifold.

The ultimate result would be fabricated aluminum. You are correct, carbon fiber would be cost-prohibitive in light of this market segment, coupled with comparatively low volume.

so what would be the weight difference between stock and yours?

Likely to be inconsequential, really. The stock composite (plastic) unit is pretty light, and that's one of its potential shortcomings in terms of boosted or nitrous use...its ability to resist bursting from pressure and/or backfire is in question.

The primary gains would be in horsepower, options, and of course...appearance!





The above shots are of our 2.0 manifold that replaces the supercharger / intake manifold. PortFueler injectors are added to this one, but we treat that as an option...we alos build them without the additional injectors.

yeah if you could make something like that that just bolts in place of the stock on i will be one of the first to buy it.

maybe make a package deal of the new intake and bigger injectors(since ours are maxed out) to make a stage 1 kit. Probaly 15-20Hp, maybe?

Yeah because because after a little tuning your IDC's dont drop any

It would be nice to have an aftermarket intake mani at a good price aroune 7-800 bucks that maintains good low end TQ but allos for great top end HP.

id like to see this as well, because then the 2.2's have another to choose from as well. things that Hahn MUST consider tho is...

1) where the throttle body will lay out - stock location or to the left to open IMO is the best idea
2) cost - if this costs more than 400 dollars dont expect many guys to be going after this thing
3) material - this would go along with cost but the thing is that we need a manifold thats cheap but strong, so there should be 2 options up for option, 1 thats high cost and very light, and 1 thats cheap but weighs more.

an aftermarket intake mani for the ecotecs is not going be cheap to make or market at a low price, since the demand is not going to be there. With the about of people who would put the money out I would expect to have a price tag around 7-800 dollars plus. We dont drive honda's and are parts are not going to be as cheap.

Bill-Is this gonna be designed towards boosted cars or na applications? Would this have options as far as ports for injectors/n2o/meth/etc? Wouldn't mind switching things around as far as intake/resivour/etc as long as it performs nicely. Also wouldn't mind spending around 700 bucks either

I feel that an intake that is primarily designed for modified, but still street driven NA 2.4's would be an axcellent product, not only would it serve the LE5 guys, but higher output 2.2 engines could benefit from the increased breathing as well, I am not sure that a second 2.0 style intake is necessary. Is it being suggested that the 2.0 intake wont function properly or isnt capable of supporting a high effor boosted LE5? I find that difficult to believe.

Again, I feel the most widely needed product is an intake manifold with runners longer than the StreetRace 2.0 manifold and a plenum tuned to these runners and for naturally aspirated 2.4's(and potentially the 2.2) that are running a tune, full exhaust systems, and upgraded cams.

Couldn't agree more. A nice fogger system and upgraded valvetrain along with the above would make a killer street/strip set-up.

Mike is exactly right here. For us N/A guys low end torque is going to be key. When I ran my car on the Dyno we ran it up to about 7200 RPM and it really never started dropping power bad. If I were to increase lift and duration on my cams, that will shift the power up even higher.

I know he meant this as a joke, but seriously, please do not put something all over it that will brand it to a specific model. As you can see here, you are getting input from all three GM lines and this may be something that is useable on the HHR, Solstice, Sky, G6, Malibu and maybe more.
