hey guys,
i was wondering has anyone seen any track times or even track time improvements with a FAST 102 intake on a stock bottom end LS1 with h/c ? ported or unported ? 90mm tb or 92mm tb or 102mm tb ?

i know vengence did a h/c ls1 vette awhile back with a 102 intake and pick up nicely on the dyno. are there any track numbers out there anywhere ? just curious ,since FAST 92's are impossible to get nowadays.

please note that i'm not trying to start any debates or arguements ,just asking a question ,ok. thanks in advance .

 

Ok. I will take in consideration that is it now Friday and most people haven't been to the track yet . So ,with that being said.......I'm sure by Sunday someone out there can tell me if they have any success with the FAST 102 intake on their stock bottom end , head and cam LS1...right ???

Just remember guys, I'm not trying to be an *** . I just want to see track results before I spend my money. I'm sure all of you who are wondering the same feels the same way.

 

A FAST 102 setup is not a bang for your buck mod. Its more so a squezzing every last bit out of a setup. Most I have seen from a ported setup is 20rwhp gain, so figure about 00.20 worth of a improvement for about $1200 give or take.

 

Yeah it's a pretty steep price for .20 tenths. I figured if you can get at last .25-.30 tenths on a h/c with that intake ,then I would have to kinda lean towards it. And I am trying to get every bit out of my set-up without stripping the car or even removing my a/c.

So would you think a 102/92 set-up would be the right way to go ?

 

Mac, FWIW, I picked up 10 rwhp going from an ls6 intake to a unported fast 90/90. I also switched from 3.42s to 4.10s at the same time so my numbers most likely would have been greater. From what I've seen, 3.42s to 4.10s shows up as a 10 rwhp loss. If this is true, the fast gave me 20 rw.

Hope this helps.

 

Thanks for the input ,Dave. 20rwhp is very impressive for 90/90 set-up. Hopefully , more folks will chime in that has seen an ET improvement switching from LS6 intake to a FAST 102 or even LS6 to 92/92 set-ups. So far my stock LS6 intake is holding up pretty good ,but I would consider getting the 102/92 set-up if someone can show me some ET's. Dyno numbers doesn't mean much to me ,man.

 

Mac if you get one let me try it on my SI car.......

 

of all the people I know ,you would be the one to get .3-.4 tenths out it with that " tin-can" you got , Joey ..

 

I dropped 2 tenths going from my ls1 intake on a LT/lid/catback car to a fast 90. only reason I'm running a fast is I got it with a nw 90 tb for 500 shipped.

Then I dropped another .26 tenths going to custom 3'' true duals, but I don't think I would of picked up that much if I didn't have the fast on there.

hope that helps! also mph picked up too, but I can't remember by how much

 

Thanks for the input ,Lynx .

 

no track times but here is a dyno for you...

best i can do for ya right now...

 

Nice numbers !! What size gorllia dick cam and heads you have on your ride, Chrs1313 ? Did you have a 92/92 set-up with the same heads and cam you have now ?

 

yup same heads and cam with the ported 92/92

build info is in the threads listed...

 

cool. can't wait to see the track times to compare how much you picked up at the track.

 

I gained around a .10 with my ported fast 102. It was not a direct comparison because i took out around 150 lbs to.

 

Thanks for the input NMass399 !! Sorry It took me a minute to get back to this question. I'm still looking for any ET post from any H/C guys on stock bottom end with any comparison from the LS6 Intake to a FAST 102 Intake??? I don't really care about dyno numbers. I want to see track results . Anybody ??

 

I"m thinking its going to be hard to find someone going from a 78 to a 102 without first going to a 90 or 92 first.

 

LOL... Yea, Joey. I really want to belive that the FAST 102 is really worth the money but it seems that this product isn't really selling well at all. Like I said before , I'm not trying to bash it ,I just want to see track comparisons before I spend my money. Case in point, every A4 guy bought a Yank or a Vigilante " AFTER" they seen track results from other guys and even vendors. It was also done with the FAST 92mm Intake when they first came out . Nowadays , it seem that people don't want to post anything anymore . A Vendor will post something ,but it will be a stroker motor they are talking about most of the time..LOL.. Oh well .

 

yea Im curious to know what et's from a ls6 to a fast 90 or 92. Im either gonna buy some big and littles or the fast intake. Just trying to figure which is the best bang for the buck

 

I've seen .2-.25 tenths gain going from LS6 Intake to a FAST 92/92 set-up on several cars in my area. So I know the FAST 92/92 works !!
