Last week I had ECS install a FAST 90/90 intake setup on my H/C 2000 Vette coupe. This however is not the off the shelf FAST plenum..I sent the intake manifold to Tony Mamo of AFR so that he can perform his porting magic and maximize the potential of my latest mod. The results were outstanding! :thumbs: To those who are running a H/C setup, adding a FAST90 wakes up the car even more. I highly recommend it!

My setup:

224/228 .581.588@114 comp cam
AFR 205 heads milled .020
Kooks 1 3/4 headers
Blackwing CAI
Z06 Intake
4.10s

Here is my previous dyno sheet with 3.42 gears: (never dynoed with the gears)

416RWHP/383 RWT



Heres my dyno after the FAST90/90 through 4.10s

429RWHP/402Tq




So after calculating in the gears, I gained 24RWHP and the TQ jumped to 402! Im estimating the dyno would have read 405HP before the intake swap. (-10hp reading) Not that I care much about dyno numbers anyway...its how the car runs on the street that matters to me the most....believe me its different now!

After John@ECS bolted down the new FAST, Doug takes it out to the street and then hooks it up to the Dyna Pack for a re-tune. As usual, his tune is dead on! I have zero loss in drivability with the addition of the FAST. no bucking, no surging,no compromise! There was no loss in low end TQ. Throttle response is so much nicer..makes the car alot more fun to drive. The big improvement is after 4k RPM and up...the car pulls harder all the way to redline. Just more power across the board...its awesome!

Thanks to ECS and Tony for making my car more enjoyable to drive.

Here are some pics of the go fast goods...

FAST 90 returns from Tony

Very very nice gains Congrats man.
I really wish you didnt install the 4.10 I think the car will be close 435-440rwhp

Great work like always Tony.

 

nah, 4.10's rock...dyno numbers are not that important, I want some ET's

 

I am not trying to be a jerk but there are a lot of cam only cars making close to that power. Does the car drive ok? Who did the tune?

Good gains from the intake.

 

I dont think theres many 224/228 cam only cars making 429rwhp and look at all that power under the curve.

 

You might want to stop living on the internet, where everyone's car does 10s in the quarter and they date a supermodel. I know lots of real life cam-only cars that make around 370-380.

 

You're killing me. I have Tony's FAST on the car, and his "worked" AFR 205 heads and the AFR 224/228 cam sitting in my basement, which I can't install right now due to a hand injury

Great results

 

I agree, gettting a good dyno number vs the results on the street with the gears is not even comparable....4.10s make the car pull quick out of the hole!

 

He's talking about all cams, not just a smaller 224/228.

 

Yeah....cause thats how I live, and don't forget my 12 inch dick either. Sorry for my .02

I have read a lot of cam only cars making 370-380. I do not have the "real life" experience that you seem to have but I have read a lot of different combo's and some of them seem rather high.

OK, 380rwhp for a cam car, 25rwhp from a set of AFR heads and another 25rwhp for a ported 90/90? Maybe a set of PRC heads and LS6 intake would have been more cost effective. But what do I know.

I am not going to get into a pissing match because I am not trying to dog the OP, that wasn't the point of my post. I said that because his power seemed low to me and I wanted to make sure everything was ok with his combo. Now that everyone has shown me the way I understand now. I am truly lucky.

I won't post again. I am going back to my 10 second civic........

 

great to hear another awesome gain coming from a T. Mamo ported FAST setup. I bought my FAST90 used and ported by Mamo and after installing it i went from 409/386 to 443/402 with my Comp 224 .581 @112 lsa and Patriot Stage II Ls6 style heads (59cc) stock 10-bolt 3.42's. That was a gain for me of almost 35rwhp/16rwtq...

congrats to the OP on seeing such great gains!!!

 

The thing is, I've also seen many 400+ cam only (with other boltons) dyno sheets, even some A4s, yet at the local dyno it is VERY, VERY rare. I just chalk it up to different dynos reading diffently and fall back to the old saying that they are merely a tuning tool. No sense in anyone getting worked up over it.

To the OP, congrats on the new intake. The good weather is upon us. Enjoy!

 

Not sure, but I think ECS is now using a different dyno, not a Dynojet. Their new dyno loads at all RPM and is similar to a Mustang. That and the gears will likely result in lower numbers.

 

great numbers, i bet the seat of the pants performance is AWESOME. 224/228 cam. isnt that a common cam for FI cars?

 

Three truths that rarely surface on the internet:

1. A to B dyno numbers mean way more than the B number by itself
2. Stingy but accurate dyno numbers mean way more than the inflated claims that sell lots of parts
3. MPH at the track, race weight and density altitude will sort out all the bogus numbers out there

A dyno truly is a tuning tool, but we always want to put faith in the results. There are a lot of claimed 450+rwhp cars that can't break 120 mph in the quarter. I wonder why that is?

Yes, enjoy!!!

 

Just my opinion but the 401tq is just a peak number. Compairing the two tq. lines your LS6 intake makes a beautiful broad power band. The Fast curve looks alittle too choppy. The tq. is up then it levels out then it dips then levels out again. For the cost of the intake itself, the cost to have Tony mod. it, less it didn't charge you, and the cost of a 90mm TB doesn't seem to be worth the $$$ for just peak numbers. I think you could have gotten almost the same results with a larger TB on your stock intake. I still like your numbers before the intake. Take care.

Out shoot..i just realized you had AFR heads too?? Man i thought the heads with that cam would have made more even with the LS6 intake.

 

Well bro, I won't rain on your parade. Looks like you got a good boost in performance courtesy of Tony Mamo's ability to port. Good results !!

 

I wasn't trying to rain on his parade. I just believe he deserves better for the
extra $1,300+ that he spent on the upgrade. But track times tell a better
story. And i really hope he gained more than 25rwhp with the AFR heads.
I've been looking at those heads, or the Terminator heads, or having my
stock 241 heads ported by TEA or maybe LLyod Elliott. Being a A4 car in my
'02 SS i'm more interested in the under the curve tq./hp. Don't care about
peak numbers.

 

Yup, car drives like a raped ape..no joke! ECS did the tune..pulls real smooth all the way to redline

Ive beaten alot of higher HP cars on the street so dynos mean nothing to me

 

very common grind for FI but it also a nice street cam for the NA guys!
