Hey All,

As most folks know, I have been working with Pete Incaudo from VMax Motorsports for about the past 10 years or so. He is the designer of the 90mm CNC TB that has had several hundred happy customers here.

With the coming of the FAST 102mm intake, several folks have jumped on board with generally good results, but most, despite tuning, can still exhibit some off idle stumble or hesitation. This pertains only to those that are still using the stock 90mm TB (ported or untouched). Those with a 102mm TB have not had these issues as long as the tuning is done correctly.

What we, or more precisely, Pete has found is that the lip at the back of the TB is causing quite a disturbance in air flow as the blade opens up. What Pete has been doing for the past 6-8 months is try different "Velocity Ring" configurations that help match the flow of the 90mm TB to the 102mm intake mouth better and eliminate this issue. Some will ask "Well, doesn't this just make it into a FAST 90mm or 92mm Intake?" In a word, no. The inside plenum area and runner design work better on the 102 versus the 90 or 92. Besides, if anything is going to make a 102mm intake revert back to a 90mm is using the stock stock housing, ported or not.

It has been tested on several 2010 Camaro SS's as well as C6 Z06 Vette's and we have ended up with a product that we feel benefits in this area for a very reasonable price.

Even on vehicles where folks were either a bit skeptical or felt they had no issues to begin with, we have recieved some very good feedback. The best has been on a Vette that the customer considered to be having no idle, off idle or driveability issues and very happy with what they had. They installed the ring and were amazed at the difference.

Now me being the airflow specialist that I am (NOT), I can not get into detail as to why this exactly works, but I know it does. I will need to get some more specifics on this next claim in regards to dyno sheets, but there have also been some small gains in peak HP and TQ, but more importantly, some moderate midrange gains. The more aggressive the package, the more the gains.

Attached are a few pics that show the ring, how big of a difference there is from the 90mm to the 102mm and how the transition looks with the ring installed. The fit is an interference fit, so nothing is needed for the install. A few folks have used epoxy or silicone as a locking device, but we feel the interference fit works very well. Makes for a simple install.

The price will be $49.95 plus $5.95 shipping and handling in the lower 48 States. Indiana residents add 7% sales tax.

I will be out of town till Monday, July 5th, but I do have 10 of these coming in and should be at the shop when I get back. Please feel free to e-mail me at thevettedr@aol.com or call me during the weekday at 407-616-2518 with any questions or to order.

You can also order via Paypal to thevettedr@aol.com and you can make the total $55.90 if you live outside Indiana and $59.82 if you live in Indiana.

Thanks

Mike Norris.

That's funny, the problems that I have heard most associated with the FAST intake was the larger TB itself. It is a tuner's nightmare and doesn't seem to make power on stock sized motors. Those that kept the stock TB, ported or untouched, including myself, have not had driveability issues. Maybe the Vette Doctors are just crazy, who knows????? If this ring works, I'm game for trying something new down the road, let's hear from some buyers.........

0Mike@NorrisMotorsports

Too much TB can be a problem for sure as bigger is not always better. But at least the transition step is not there with a 102mm TB.

Like I mentioned, there were a few folks that claimed they were happy with their current 102mm intake and 90mm TB setup and when they tried this piece were pleasantly surprised. For the $50-ish cost for them it was worth the try.

I am sure as time goes by the results will come in, very similar to the VMax CNC TB's.

Hello Mike,

I will try it...why not.

Please tell me if you can ship me one by the end of this week.

PM me if you like and I can give you all payment details.

Thanks,
Carlos

Interesting....

0Mike@NorrisMotorsports

Hi Carlos,

If you can Paypal me the money (the info is in the first post) I can get one shipped direct before I get back. They are also going out of town by Weds evening so we have a small window to get one shipped.

Thanks.

Hello Mike,sent you payment

0Mike@NorrisMotorsports

Got it DOHC and replied. Not sure if I can make it work in that timeframe, but let me know if what I sent you may work.

Thanks cencalc6. I sent the info directly to VMax to try to get one headed your way before I get home next week.

Pete has made a quality piece. The theory is based on sound principles. I have tested it only on the street thus far but results are quite good. Mid range power may be a little stouter. We will confirm this on the dyno as well as at the track.

0Mike@NorrisMotorsports

Thanks GARY2004Z06, looking forward to more data for sure.

All orders paid via Paypal should be shipping by Weds direct from VMax. All other orders will ship when I return to the shop next week.

Thanks again all.

This may sound totally unrelated but I will post it anyway for a little background information. I did a lot of mods and dyno testing of the Mercruiser 502 EFI motor when it first came out for Hot Boat Magazine. It had about the same situation as a 90mm throttle body on a FAST 102. It had a pair of throttle plates that the housing dumped into a plenum that was much larger than the TB bores. We did some TB porting and thinned the throttle shafts for more airflow and found a little more flow with a couple of more horsepower. The power gains were very near the normal variation from run to run so they were too small to guarantee an X amount of gain. My engine guy suggested that we blend a radius in the throttle bores where they entered the plenum. His theory was that the square-cut transition caused the air exiting the throttle bores to violently curl around the corner on exit and cause a lot of turbulance in the plenum right where the intake air exited the throttle body, stalling some of the intake airflow. We cut and blended a 3/8 inch radius at the exit points of the throttle body and when we hit the flow bench, we found that the flow increase was more than all the mods on the inlet side combined. I originally thought, "No way!" But after watching the mods being done and watching the results on the Superflow flow bench, I was pretty surprised. We also got the first set of dyno runs that consistently (from run to run) showed a small but consistant amount of power gain. With dry air throttle bodies, you don't get anywhere near the amount of power increase in relation to the airflow increase but even a little is worth the effort. Does this support the claims for this new part? We don't yet know for sure but as far as I am concerned, they are at least heading in the right direction.

Let us know how this works out Carlos

0Mike@NorrisMotorsports

Thank you Carlos and let me know for sure

Thanks to everyone for all of the orders. The orders recieved and paid by Tuesday evening should have shipped Wednesday. All orders recieved Wednesday and on will ship by Tuesday next week.

Have a great 4th of July weekend all

Will this piece work when a nitrous plate system is already in place?

Thank you!

0Myhardtop

Got my unit last week, thanks Mike.

Will install tonight and test whenever it dries out. I has been raining a lot here lately...we needed it!

It is a very nice quality piece and well made...nice!!!

Thanks,
Carlos

0Mike@NorrisMotorsports

Without seeing how the plate goes on, looks and fits, I would be hard pressed to give an answer. Is it a 90mm or 102mm plate?? I would say if it was a 90mm plate, it "should" work, but would hate to guarantee anything. Sorry for being so vague on that.

Let me know Carlos and thanks

Mike Norris

Captain Z

It's the 90mm. Thank you for your reply

See what happens.
