anyone believe this manifold can deliver 15-20 whp horsepower over a stock manifold...have any of you gotten this intake manifold yet for the itr...for 595.00 with the optional porting it better...whats your take on this intake by JG

 

wow, didn't know it was THAT much. From what i see it has bigger, shorter ports and the plenum is centered. Not sure if it will give an improvement on an otherwise stock motor.

This looks like a good product to add to the list of things for H-T. to dyno for the sake of us all.
Knowledge is power

 

well my motor is pretty much not stock so that is why i am wondering...i am using a type r manifold now and if i can bolt this on and get 10whp, then what the hell why not...i just spent 900 to get 15 more from a new set of cams

 

Only way I can imagine it making 15-20hp more is if you're already putting down 400+ to the wheels to begin with...

 

Edelbrock KNOWS manifolds... maybe it'll be tight!

 

It will give you around 15 or so more horse power. But its all up top from 8000Rpm to like 10,000. Its really a race manifold not the best for the street. My 2 cents

 

Looks pretty close to a Type R manifold to me....

Optimized for maximum power from 7000 to 10,000 rpm for Turbo or All Motor applications. JG prototypes have powered naturally aspirated World Touring engines to over 320 engine dyno horsepower. 7.5 lbs. lighter than stock. Accepts oversized throttle bodies out-of-the-box. Available September 2001. Excellent for transplants.

Honda/Acura Competition Manifold #4760

 

The runners look alot shorter then a ITR/Skunk2 manifold to me.

 

They said it gave jojo 20 hp so I dont think anybody else will see that much in a street car

 

Looks almost stock!!!

 

OK, I will tell you guys flat out....I saw this header tested on my dyno on 2 cars...and I immediately asked Edelbrock to be a wholesaler for them.

I only sell stuff that is good. I don't want anybody calling me back saying I "steered" them wrong...

Its freaking good. The header is good, and the intake manifold is good.

No doubt on this earth.

not doubting that its good, but where does all the power come into play...from 6000 rpm and up...i dont want to rev to 10,000 all the time to see the power gains...the other thing is, is it strong in the low end too

 

Yeah with the manifold the peek power is 6000rpm and up! But the JG Edelbrock Header is great for all vtec alplications! In fact I'm getting my ls/vtec dyno tuned at JG by Joel. I will be using the JG Header I'll post the plot when I get it done.

Jeff do you think the JG Edelbrock Header is better than JDM 4into1?

 

Yes he does

 

they are on groupbuy

 

7000-10000RPM, well kick me in the *** cause my car only revs to 7k.. will I see any gains with this manifold on a turbo LS boosting 8-9psi?

 

15-20 whp on a fully built race only turbo engine....

 

if you are talking about JoJo's car, He made 15-20hp over his OLD manifold, not stock manifold.. I thought there was oe manifold for street cars and another for race cars..

 

WTF? Man I posted a similar question like a week ago and didn't get squat on helpful responses...
