I just bough a new head and the guy i'm buying it from is giving me the option of two intake manifolds he has (great guy). One is the a Victor X and the other is the JG sheetmetal. I dont know much about the JG sheetmetal and i havent found a comparison of the two in the archives, so i figured i'ld ask. This car is being built to run SFWD, but will be too slow to be competative for a while. The goal is roughly 450whp + nitrous. Mainly this will be a street car, that hits the track on the weekends, so I'm looking for a flater powerband that ends under 9000rpm. The motor its going on is going to be a built GSR block with an 83-84 mm bore. THe head is a Type r unit with gsr cams. I'm sure the victor X would work but would the jg sheetmetal be better?

 

damn i figered i'ld get a responce pretty quick

 

As far as I know wasn't the Victor X designed by JG? PM Marauder, he works for Edelbrock and can probably answer your questions better than most on here.

 

yes they are both jg, i think. but they are diff. manifolds.

 

anyone have an opinion on this?

 

i could really use some help with this. THe other problem is that i want to hook up my direct port kit and i'm not sure if thats easily accomplished with a sheet metal manifold.

 

How much power are you making?

The Victor X manifold is made for serious power and rpm usage. Like for drag racing and staging the car at 7000rpm and always keeping the power band between 7000-10,000 rpm. Typically you'll see bad mid range power losses around 3000-6000 rpm.

Yes, both manifolds were designed by JG Engine Dynamics and I actually don't have any knowledge of the JG sheetmetal intakes.

To plumb a direct port kit to the sheet metal intake, if you want to put the nozzles in the sheetmetal part of the manifold, you'll need to weld on bosses so you have enough material to tap for the nozzles.

Intakes really don't work based on flow. They are a tuning device and work a lot on harmonics and resonant frequencies as well as flow. For your power output, it should work okay, as long as its not intended to make power in the mid range.

We have new intakes coming out shortly, PerformerX manifold line for B series engines, which should work well for both racing and street use and gets rid of the mid range power loss the Victor X manifolds have.

Is this true in a turbo application as well. My goal is to make 450whp for street use.

 

What's your setup?

When are these going to be available? Thanks, Paul

 

The B16/Type-R/LS ones will be available first (about 4-5 months away). The casting tooling is done and is at the foundry for the first sample run and if that looks good, it hits production.

The GSR one will be another 5 or so months after that, its just starting the casting tooling process now.

 

i'm still aqiring parts so i cannt give you my exact setup yet. Right now it looks like it will be a gsr block (sleeved to 84mm) with a type r head/w gsr cams. I'll more than likely run a revhard manifold for now with sc61 leading to a 3'' down pipe and a a 3'' themal exhaust. All of this will be mated to a gsr tranny with a clutchmasters dualfriction. I have about half of this **** so far. so there is still time to make changes as i see fit, or as my budget allows. anyhow i'm leaning towards the victor x, but i wa just trying to get some input. Liek i said this is primarily a street car that will see regular track use.
