wow. Pretty consistant gains throughout the powerband. How much for one of these intakes? Core and non-core.

 

[XR8TED285]

Starting in the 750 range up to 1000 + depending on how crazy you want to go. Currnetly working on a differnt runner design so we will have to see if we can even push it a little higher.And yes there is a core If you are a mark 8 guy i can get stockers for a decent price for core...

326 rwhp on the stock block? That's VERY impressive, I thought the highest a stock-B-head car had been was 315 rwhp....if so, that's even more of an accomplishment. Congrats. :thumbsup:

 

[Jwilliams]

what bolt ons?

 

[CobraJazz]

Any idea of the gains on a completely stock vs. say, exhaust and CAI? Sounds like a great alternative! What is the "Crazy" factor of the JSR shown in the dyne sheet?

 

[XR8TED285]

Well on a stock car, I can say you can expect to see 15-25+ rwhp. Umm as for the bolt ons.. I will let jimmy post that one..

 

[Doug]

Out of curiosity, how many man hours from start to finish on one?

 

[XR8TED285]

Um around 20+ hours not sure really..This next one I am doin the lower and jim will be doing the runner fabricaton...

 

[slow98svt]

Are thoes Gains just from the intake? or was it the intake and IMRC deletes?

 

[XR8TED285]

Intake also has delete as well

 

[slow98svt]

Nice, does he have gear?

 

[CY98Cobra]

I want one of these so bad, it's too bad I don't have the money for that and the tune

 

[XR8TED285]

Has 4.56s changed from 4.88s

 

[XR8TED285]

Here is the dyno of the first intake vs. stock

Here is the dyno for first ported vs the final product. Gears were changed from 4.88 to 4.56s. Car as no major modifacations ...Yet... About 70 percent of the mods on this car was built in Jims garage. never had a valve cover lifted though... This car is driven on the street and even driven in the snow..Second dyno also was with a minor retune thanks to the guys at MD. they brought some hp to the table ..

Here is the intake.

 

[slow98svt]

Thats awesome, when I get my 98 Cobra I will be looking forward to having one of thoes intake eventually. BTW is that the highest HP stock B headed car now?

 

[XR8TED285]

Not sure to say the truth ,could be.. N/a that is... Ran 11.4 @ 118 with the 306 hp setup will be intresting to see what it can do with the 326..

 

[CY98Cobra]

How could would it be if he ran a 10 sec 1/4 with a stock motor, bolt on, n/a 96-98 Cobra. If I were to have this done would I send the intake to you to modify or do you send me one and I send mine in as a core? I might start saving.
