Ported TB and FAST
Removed the Throttle Body from my C6 LS2 and shipped it off for porting through Mike Norris Motorsports ($159.95 + $19.78 shipping). Also, purchased the FAST 92mm Intake from Hinson Supercars ($830 shipped) and had it drop shipped to SpinMonster for porting and the SpinFast modification ($330). Once installed, I will visit Spin for a tune and report back to this forum on what I think of the performance gains offered by these latest Mod's.

I would be curious as to the dyno and drag strip results of a ported & modded Fast with bolt-on install vs a ported Fast only (ala Cartek, Formato et al ) with a cut firewall install. I wonder how much power is lost in the cutting up of the Fast. I heard something is lost, how much I dont know.

there is too many variables, the only way to do it would be on an Engine dyno.
the track will not give you the controlled environment needed to give accurate results.

I have never seen, read or heard of a power gain difference between that of a SpinFAST Mod vs that of a Ported FAST with the firewall mod. There are many posts and documented results showing the SpinFAST Mod to be worth the effort and cost. I prefer to modify the $830 FAST rather than cutting a hole in my Vette's Firewall. I wish FAST made an intake specifically for the LS2, but they don't. After many hours reading and studying this forum, I have gained a healthy respect for a number of Forum Members who have given of themselves to help other members on this Forum. Guy (Spinmonster) is one such person. I trust his judgement and anxiously await the arrival of my SpinFAST Intake and Ported TB. Once I have them in hand, I will install and report back as to the SOTP improvement in performance. Then I will have Spin Tune and will follow up with a Dyno to document the increase realized by this modification. My last Dyno Tune was performed by Thomas Graff of the Corvette Connection in Denver. I have my numbers from my April 2008 Dyno and will compare with the new Dyno following my tune with the SpinMonster.

Spin modded my FAST and AintQik ported it. It's rediculously smooth, as AintQik put nearly 20 hours of porting work into the FAST.
The final increase with Spin's tune rounded out @ 40 RWHP and 40 RWTQ.
Bottom Line: I don't think the mod (to make it fit with the firewall) reduced any HP or TQ.
Cheers!

And yes I have dyno'ed quite of few of my ported manifolds before and after modding the back of the units and the most recent FAST's dyno much higher as porting techniques get better and better as time and experience grow. The back of the manifold isnt in the airflow path to any of the runners.

The mod to the back is not in the airflow path of any runners and there is no loss in power. Over the years the ported FASTs I've prepped have gotten better and better. They dont dyno less in anyway what so ever.

Aintqik (RJ), is my neighbor and close friend. RJ and I dint charge Lou (also a friend and neighbor who watched my house during my last vacation but fell off the planet with his new job making lots of money) for porting the FAST or modding the back and he paid 200 for the tune which required a 100 dollar license fee to be paid to HPtuners. Install was also free.

Received the SpinFAST Modified Manifold today from SpinMonster. If it performes as good as it looks, I will certainly notice improved performance. I asked Spin for the Matte Black (Flat Black) Finish. Looks great! Once I receive the Ported TB from Mike Norris I will begin the install. I will report back with progress updates.

I'm a new member & I'm very far away,
I just got my new FAST 92 for my '06 C & am waiting for the firewall clearance,fuel rail adapter & Map sensor relocation kits.I'd like to avoid cutting up my firewall if I can & save some money as well(shipping,$exchange rates,etc.). Is the mod to the back of the intake something I could do myself? I'm a mechanic,so I know my way around an engine, but I'm not an intake expert like you clearly are. Is this mod one you'd be willing to share( with pics & instructions) or is it a proprietary thing? PM me your response if you like. thanks.

I have done manifolds for customers in the UK, Middle East, and Canada. I take PAyPAL so the exchange rates are minimal as are the shipping rates if you are flexible. The charge is offset by the savings for all the parts you ordered, none of which are needed once I mod the unit. The porting doubles the effectiveness of the unit as show by both track results and dyno results.
