They tested the Victor Jr. on a n/a 2v with ported stock heads,comp 270ah cams and the usual things with full exhaust and they made just over 400flywheel hp with it. So that manifold works for sure.

 

N/A, I recommend the edelbrock intake for anyone that can run tight LSA cams. The tighter the better. The only off the shelf cams that will work worht a darn with it are the VT/Cushman stg 2s but they have too much exh duration. With TFS heads you can use cams that have everything the edelbrock intake needs to work great.

FI, the intake works great but if you plan to keep the rpms below 6500 just stick with the PI intake. The gains provided by the HPS, TFS and Bullet intakes aren't worth the money.

 

that's kinda subjective.

most people would be happy to gain 25-35hp for less than a grand with a bolt-on part.

 

What's subjective? My comment about the HPS, TFS and Bullet intakes? Of course it is, but you won't gain 20rwhp by adding one either. I haven't seen any of those intake provide more than 10rwhp over a PI intake (magazine articles not included).

 

I was referring to the worth the money statement. Them not being made of plastic alone is worth it to as many as not that would consider a new intake in the first place.

We're on the same page for the most part... NA those intakes tend toward the lower end gains (on a 4.6 closer to nothing-10hp, on a 5.4 10-20 or so depending on many factors) but FI I have seen the 20-25hp gains on the dyno from 2 of the intakes you mentioned.

 

Thanks Spike for putting this very specific information on here. It will help come parts selection time in the future.

 

I have to agree with you here. YESSSSSSSSS ... I would much rather have an aluminum or magnesium intake over a plastic intake any day, in spite of any claims that plastic runs cooler. Can't be that much difference.

Although I haven't bought one (yet), I'm impressed with the HPS intake and wish they would still offer them at a discount. It would be worth the splurge, even if I wasnt going to do a motor right away.

The BULLITT intake is no slouch. If I already had one, and if I was to build a 5.4, I wouldn't hesitate to run adapter plates to see how well it worked before I splurged on the Edelbrock and/or the HPS.

Just my opinion is all.

Again ... sounds impressive you pulled 400 HP on your motor. CONGRATS are in order !!!

 

The Comps will work with stock heads but and are kinda neccessary with the PTV issues that come with long duration low intake LC cams. When going with TFS heads you can narrow the LSA by about 8 degrees which really improves the entire powerband, both hp and tq. Get the LCs right and you'll make power. Pick your cams by duration only and you'll end up leaving a lot of power on the garage floor.

NMRA factory stock 4.6s are making over 400rwhp (not flywheel) and they are using the bullet intake and PI or SVO heads. Put an edelbrock intake on one and the power would increase by 25-30rwhp.

NMRA Pure street n/a engines use TFS heads and are turning in 10.2 quarter mile times...unreal.

MMR has made over 400rwhp with the edelbrock intake, TFS heads on a stroker on 91 octane.

This is the reason I'm switching from 4v to 2v.

 

This is all very interesting and I appreciate knowing all the facts I can before I start buying parts.

One question I have now ... What kind of numbers have been produced with the TFS heads AND the TFS BULLITT-style intakes?

 

definitely adding these to the list along with mt 5.4 2v

 

On a stock 02 gt what will i get from the victor junior?

 

Reduced low end power and a small gain up top. The largest gains at after peak occurs as the shorter runenrs allow the pwero to ciontinue out further. However, the stock cams are not agood match for this intake.

Good cams for a stock 4.6 short block with this intake would be :
226/224, .550"/.500", 108LSA no advance.

A 5.4 would get 234/232, .550"/.500", 108LSA 2 deg advance.

A forged bottom end with TFS heads would get more duration...a lot more.
