Default Fast 90/90 Gurus Come In

i was wondering if a ported fast 90 intake (from mamo) and a nick williams 90 tb would be overkill for my upcoming setup.stock bottom end, afr205's,lt headers,3500 stall,12 bolt with 4.10's,tsp magic stick?also would i need to upgrade my fuel injectors.thanks everyone

With the setup you're describing, I gained 28 rwhp on my stock bottom end car with AFR 205 heads and a teeny-tiny 215/230 cam. Not overkill in my case. With your bigger cam, your gains may be even more. It's an expensive mod, but one that allows you to make more power without compromising driveability.

I don't think it's overkill, either...I'm running a ported/port-matched FAST 90 (by Rapid) with NW TB on my stock bottom-end...with MTI Stage II LS6 heads and a Rapid Dominator C1 cam, I turned 451 rwhp/396 rwtq SAE through a M6/10-bolt...

Lawman...were the TB/Intake port matched by Rapid?

Can the heads/intake/TB all be port matched at once for maximum gains?

Mikey (Rapid) ported the FAST intake and port-matched it to my MTI heads...I haven't heard of anyone doing any porting on the Nick Williams TB...at least not yet...

In case you missed it, here's what I gained by swapping my LS6 intake and ported TB to the Tony Mamo ported FAST 90mm intake and Nick Williams 90mm TB. Keep in mind, this was running a small 215/230 CheaTR cam and stock exhaust manifolds and cats. Same dyno, one day apart.

Hey Guys...

I have been crazy busy lately dyno testing a 383 LS1 (results coming soon), as well as getting ready for my Wedding and Honeymoon (next weekend), so I'm going to be out of touch for a little while over the next couple of weeks.

I think Patrick's dyno gragh tells the best story but the modifications I make to the intake will do the following:

Add 5-7 CFM of actual intake flow if tested thru the intake (compared to the same FAST intake un-modified).

Show a gain in TQ of about a 10 ft/lb average across the entire curve....even as low as 2500 RPM's which can be seen clearly on Pat's gragh (most people claim a stock FAST will hurt bottom end power and TQ....My experience on the dyno calls it more of a wash (maybe a few less ft/lbs), but it is clear the modified unit wakes up the power everywhere.

Extra TQ (over an unported unit) tends to taper off a little upstairs, and you should see about a 4-7 gain in peak HP #'s. My thoughts are that you will feel the difference the most after grabbing the next gear....it will "recover" much faster with the extra TQ thru the middle of the curve and obviously have a little more urgency to scream to redline again. Also, these numbers could be conservative, especially after seeing Patrick's results, but I prefer it that way.

For guys looking for "all the money" out of their combination, this modification is a no-brainer in my book and I feel one of the larger contributing factors to the huge TQ numbers my personal 346 put down with a small cam and a little over 11 to 1 CR (435-440 RWTQ).

Doing this work is something I do on my time as my work load (and personal life) permits....If anyone is interested in getting this work done, I prefer to exchange information either by phone or PM's. Keep in mind I am going to be out of pocket the next couple of weeks but will do my best to get back to everyone as soon as time permits. The work I perform is time consuming and is definately not some "fluff and buff" (there is a pile of plastic on my workbench when I'm finished porting one intake)....Pat can vouch for the quality of my work as well. Also, in my absence over the next couple of weeks, I'm sure he could answer most of your questions as he is very much up to speed on the process and has done ALOT of R&D on these engines himself. (Sorry Pat...hope you don't mind!)

Thanks guys,
Tony
