Looking for dyno Graphs of cars with a stock style intake Fast 90 92 102 you get the point making powe past 7000 Rpm. And any info on if it really can or has been done?

Sorry I don't have a good graph in RPM, the dyno was having problems with the tach signal pickup. 147mph = 6900 rpm and this is with a 224 cam. I've seen graphs of 408's making peak power around 6800 with a fast. Mine is not a stock fast, I spent a lot of time porting and aligning the intake ports with the heads. With a different cam I could see moving my peak up higher but the Fast intake is really not ideal for a 7000 + rpm setup.

^ so this one peaks at 6200-6300...doesn't fall off to bad till it hits 6900ish...pretty stable cam and valvetrain...

Mine peaks around 6100 but it has a much earlier IVC point than most cams. There are probably only a few guys who know how to properly cam a stock style intake mainfold for high rpm, but that is counter productive. If you had a solid roller setup I could see you making peak power around 7000 rpm but hydrualic setups have their limitations around this high of rpm. Yes people have spun hydrualic stuff pretty high but that is not with any XER/LSK/LSL lobe profiles.

Take a look at Badd SS setup, the people involved know how to setup a high rpm 346. He has a super victor, which really is the only way to go for this type of RPM and he peaks around 7000 but holds to 7500 rpm. Whenever he gets his car back out it will be ripping off some impressive times.

There was a black WS6 built by Cartek, ported 243s and a big cam making 507/433 spinning to 7500. He was using a FAST 90

If only you knew haha I will fill you in haha. I have the heads and cam and i am going a hole new path with it. Going to be pushing it way harder then before

and as for Badd SS yes i know the setup well and all looking to be at his power ranger to bad he never had a good clutch.

My 90mm Fast peaks about 6700 rpm, AFR 205's (Both ported by Tony Mamo) 450+ rwhp all the way from 6000 - 7000 rpms

This setup is going on a ERL 427 LS2 short block in about 3 weeks if it is delivered on schedule ... then we'll see what numbers we get.

yeah it was peaking at 6700 too just like the others posted...

here is the graph

and he was shifting lower than 7500

here is mine 6700-6750 peak

This is a 417 stroker I built making big power with a ported 102 I did....

Hardly rolled over at all at 7K with pretty good sized shortblock pulling on it very effectively.

Properly ported I think a new FAST 102 is good for 7-7200 in a 400+ CID package.....7400 or so in a smaller heavy breathing combo (really aggressive 346/364 with good heads, healthy cam, etc.)

Tony do you have any dyno graph's of a aggressive 346. Thats what i am doing should be spinning close to 7300.

yeah good ole 102...I really like the runner design in this manifold vs the 90/92

Tony Mamo @ AFR

iTrader: (13)

I do also....

Better runner design, much sturdier (stronger) and it has a much better injector angle aimed right at the short turn of the AFR heads....LOL (and most good aftermarket heads I would imagine!).

Speaking of that injector situation though, note the hole/tunnel where the fuel sprays is higher up and can create issues with some heads that may not have the cathedral section of the roof raised high enough in that area (you would look thru the injector hole of the manifold and see the hole partially blocked off with the head).

I had to redesign the AFR V2 heads in that area and got lucky I could implement all the changes before we finished up all the CNC tool paths etc.

Bottom line though is the 102 was a big improvement over the older FAST intakes and even though its not perfect (injector location as I just touched on, install/fitment issues common in Vettes), it's worth the hassle to get it installed if your looking for ALL the money from your combination IMO.
