You tell me what mod gives you 25-30rwtq in the mid band for $1,000? "ported Fast 90," the best mod for the $ period. End of story over and out, ask the guy's that have them not the ones that don't.

 

If knew where I could get a ported/polished/painted/C6 mod'd FAST intake installed for $1000, I'd do it in a heartbeat. I paid $3400 for my headers, CAI, stat and tune and netted 40 RWHP. That's $85 per horse. If the FAST nets 20 RWHP for $1000, that's only $50 per horse. Great deal. That doesn't even account for the gain before the peak. What I really should do, is a before/after dyno and measure horsepower across the band.

 

Craig, looks like you and Spin did a great job with the install, it looks great!

One thing I noticed though on pic #8....did you change out the valley bolts, the pic looks like the OEM's?

When I did mine I took the stock bolts and passed them on a grinder wheel to lower the head height to avoid contact with the botttom of the FAST.

 

No need to. When I had mine done by spinmonster, I recall supplied with Fast 90 were new allen tip bolts eliminating the need to shave the old ones. Yes I now recall even better, I was tightening them by hand.. :-) and spinman torqued them to specs.

 

Yes, Cameron is right. We changed out the valley bolts to lower, round head allen bolts. I thought I had taken a before/after pic...I guess I was too excited about getting it done..... Sorry...:o

 

It is a great deal, check your PM.

 

You can probably get one ported and modified for $1,250-$1,350, the installation is a different issue 'obviously if you install it yourself, it only costs 1250-1350,' takes a tuner no more than 2.5 hours to install, and depending on other engine mods. Retuning may or may not be necessary.

My particular tune was done by spinmonster and took a few hours to dial in accurately, which netted even more power. Craig's didn't really need a tune by what I witnessed, yes I was present with the crew that night, Tony (craigs' assistant) was also installing a set of kooks headers (spins old ones) and x-pipe hiflo cats, for a friend of mine.

 

We had already tweaked my tune for the ported LS2 manifold I had, Spin left it a little more suited for the FAST, so there wasnt much to change intially. We couldnt dial it in any more due to the weather that night, but I think there is actually a little more left in it... We'll play more when the weather is warmer.

I cant stress enough the difference in throttle response and performance this combo makes, Vararam feeding a ported TB, feeding the FAST....a small 1/2" press of the pedal snaps your head into the seat...it's like having a cable throttle again.

 

Gains with or without cam? Evilways had commented that though his FAST showed gains on the dyno, none at the track. Any track numbers to back up the mid band gains?

 

Track numbers? None, but there are several threads here posted showing 25rwhp and trq in the mid band on a dynojet. In terms of track results, that's subjective, different day, variable da, can result in plus or minus, results, there is no denying, that there is huge midband gain and most likely on a ported Fast 10-15 peakhp. Now how you drive at the track to harness the gains is also subjective "driver experience."

Spinmonster has posted numerous graphs on this subject, and maybe craig has access to to some graphs..

 

I have comp 228-232, 575/588, 113 LSA, and with the cam gains are even higher in the mid band. I dynoed 413rwhp/380rwtq (corrected) with 4.10's, before Fast 90 and tune, and to post accurate results I will use the same tuner and dynojet. This should happen within the next 2 weeks stay tuned.

 

I certainly believe the FAST makes good power with a cam and/or heads but I was wodering more or less with stock heads and cam. Once I go as fast as I can on my current combo, I might go with the FAST, see how quick I can go without opeing up the internals just yet. Just some weird thought process of mine. I would love to have 20rwhp/tq in the mid range, stuff you feel.

 

You do feel it, I am running stock heads and cam. I am trying to get back on the dyno this week. Ill post the before/after sheets...but whatever the numbers are, to me it was worth it for what I feel and the speed increase it gave me.


Oh yeah, I have a ported LS2 manifold if anyone is interested....

 

stock cam and heads here too. I like the FAST. It did make a dif IMHO got the dyno to prove the SOTP dyno too.

 

The thorttle body will touch the S/C (ATI). To use the FAST with an ATI requires the use of the trailblaizer's TB which has the motor on the opposite side. Its a direct fitotherwise and the TB requires no other special steps to work with our cars.

 

100% false on just about everything you asked about. The manifold is 735 shipped and requires 50 bucks in parts to work. I am tired of stating the same info over and over on the power gains which are 20rwhp at peak and 25/25 for HP and TQ in the midband. That maes it one of the most benefitial mods you can do unless youre a peak HP guy and dont port it, in which case you get 12rwhp at peak for a cost of about 80/HP. It actually ranks ahead of headers for gains per dollar.

Do a search for my extensive typing on this topic. You will find threads with 100 posts telling you everything you ever wanted to know about the facts and the myths. The entire purpose of this DIY project was to show people that even with minimal skills you can have all the gains for less than 800 bucks.

 

Excellent point to cover here. When you say a track, you mean a 1/4 mile track. If you gain 15-20 at peak depending on a cam, it would manifest itself in a tenth. That is a close vairiable. Cartek tests it at a track and uses them for all their max effort installs so the data from those 2 sources dont match. The variables are too many to expalin why he didnt see a gain at the track including the obvious one....tuning. The FAST will alter the tune. In Craig's case his tune was off in a direction corrected by the FAST where Cameron and I played so much with his tune that it was exact to the stock manifold. Cameron didnt see most of the gains until the tune was done so if Evilways just installed it without a tune then I dont doubt his findings are true.

All that said, the FAST is a massive mod for street drivers and for road race guys. The gains in the midband that are disproportionate to the rest of the curve suggest that a boost such as had by the FAST between 3500 and 5500 wont make a car as fast in the 1/4 as it will on the street with roll-on races. Not everyone goes to a 1/4 mile track or builds a car specifically for that purpose. Even so, the FAST outdoes the ported stock even in the 1/4. Bone stock and tuned it will give 12rwhp at peak as repeatedly shown by Tont Mamo and not everyone wishes to rehash all of this over and over. Do a search if you still arent convinced.

Personally I will take power anywhere in the powerband. I drive my car o the street and it is definitley better with power everywhere in the power band. Many guys get in the car and drive at 2k-5k rpms and comment on the power from that too not just 5k-redline. If you are the type of guy that needs to see only peak numbers, overcam your car, use heads with oversized runners, and use Kooks 1 7/8 and you will have 500rwhp easy. Dont ask why it feels like a slug on the street though.

 

I've got to agree with everyone who has felt gains from the FAST. My car has heads/cam, and had a ported ls2 intake. Swapped in the FAST manifold and I could definitely feel the difference. Tires broke loose much easier and I loooove doing those rolling burnouts. Spinmonster is going to do a port job on it and do some real tuning so we can get the most out of it. I really think a good tune is a MUST to get everything you can out of the FAST, but the gains are undeniable even without tuning.

Hey Guy, you get those pics I sent you?

 

I emailed you back that they didnt work. Send it to my yahoo acount with the same name.

 

Yea I sent them to your yahoo last night, should be there, or maybe check your spam?
