Anyone make a "4 pack" for the 4g63?

[98TsiAWD]

I have seen "6 packs" made for the 95-00 Avenger/Sebring v6 and "4 packs" made for the 420a engine I think also. And they have HUGE dyno hp gains for the N/A cars.

Now I am curious if anyone make a 4 pack for the 4g63 that would basically replace the intake manny completely and the 4 throttle bodies would face up towards teh hood but have enough clearance to run a Upper IC "S" pipe made specifically for this 4 pack to hook the boosted air directly into each throttle body.
And if noone makes it I wonder if we could find someone willing to do it?

I think I might have found one.

I am emailing them for more info and pics on a 4g63.

damn that looks sweet. Why would you need a special S pipe tho? It looks like the TB's are right at the beginning of the plenum runners. I could be wrong , but that's always how i thought they worked.

Well originally I was looking at some from another website where all the throttle bodies were exposed (no box around them). You could either let them suck in fresh air or put filters on top of each throttle body.

Now on that site I linked above I noticed they stated that their carbon fiber box could only hold 3psi, in my email to him I told him we would need something that held 25-30psi.

Here is what the ones I was first looking at look like:

Heres the email response I got from RPW:

We do not have any that would suit your setup at this
time. check back with us in about 5 months as we are in
the developing stages for it. Price with haltech E6K
computer system is $2,000
Thanks

Is the haltech a standalone?

By going with that setup, you are eliminating the MAS and hence need to go with a standalone setup. If you are going that far, there are bigger gains to be seen from other mods with the same money.

But what about completely built 10 second DSM's, if they were to get the "4 pack" wouldnt they make more hp/tq than they did before?

this is an interesting question.

one good way to analyze this is to look at the skyline. skylines come from the factory with individual throttle bodies, but have a sealed box around them for the ic plumbing.

on the high end of skyline tuning people have gone all different ways. some simply bore out the 6 individual tb's, other's use 1 large tb, some use 2 moderate sized ones to get equal flow to all cylinders.

bottom line is that they all make a shitload of power with neither design clearly dominating over the other.

 

[nothing stock]

The main reason people use multiple throttle body intakes is for throttle responce not for HP. A single TB on a custom intake with bell shaped inlets in a properly sized plenum will allow you to run a smaller diameter intake runner (higher velocity) with the same flow in comparison to individual TB intakes.

Throttle responce on a N/A car means a lot. Use the right parts for the right aplication.

I'm pretty sure Glazar was running individual throttle bodies. At least that's what Turbo magazine had printed.
