Looking for a good high flow intake!

93 Cobra needs input · 01-01-2003, 02:39 PM

I'm getting my 331 stroker ready for spring and have decided the Cobra intake may be to small for my combo. I have read alot of good and bad about that intake and need some good advice which intake would be my next logical step up. I'm thinking TFS-R or the performer RPM I think the true victor intake powerband is out of my rpm range. The car will see alot of track time shift point 6,500 with 4:30 rear end gears and the victor jr heads, I'm sure the heads are way big for now but I want to have 9psi boost on the motor by early summer. Thanks for your advice.

Holley Systemax is my suggestion. Or wait a month or 2 for the Performer RPM II to come out. Its supposed to make a good amount more power than the previous RPM and a few more ponies than the Holley

Myself I bought a Cartech (breadbox) for GT40 http://www.cartech.net/mustangparts.htm
but I think I may have over done it for my mods.
I'm 331, 351w port/polish, b303,70mT/B,ram air,Mac equal, 150hp adj Dry NOS I haven't recieved my engine back for the machine shop yet (next week) so I have no clue what to expect. I think I my have to find a GT40 upper or Exployer. But I'm guessing.
Good Luck

I have another question. With the added cubic inches of the stroker, the intake powerband would lower I think or from what I've read. Do you think that the victor on a 331 would act more like the performer rpm on a regular 302. It seems like from what I have researched the victor is way big for a 302 but would it help the 331 which needs more air anyway?? Would the victor be somewhat streetable? Thanks guys

I have the victor on my car I also have the AFR 205 heads. Mine is a street car that I plan on shifting at 6500. With the 331 and boost you will drop the rpms of the victor down to about 6700 ( thats what eldebrock told me) It drives fine on the street was told my car would not have an tq with my combo. Which was wrong my car has plenty of tq.

If you think a Victor Jr. is out of your RPM range, the TFS R will be too. I cast a vote for the Holley Systemax II or a Performer RPM, unless you plan on going past 6000 rpm on a regular basis.

I never knew that they made a Victor Jr EFI intake. I was thinking the Victor. I am happy to here your combo works forcedpower, that is exactly what I was hoping for! I am thinking that the new performer RPMII looks like it might fit my powerband well, edelbrock claims it is alot better than there previous design. It looks to me like the RPMII is exactly like the Holley, tapered runners and same looking cross section. Wonder when it is going to be available? Do you guys think the performer RPMII would out flow my Cobra intake by alot? Thanks
