Theres about a $200 difference when buying new...is it worth it on a LS2 car that the only other mods are long tubes, axle back and SLP intake?

And wheres the best place to buy an already ported FAST 102...Ive seen them for about $1050 and seen non ported for as low as $829

 

Sir please see my thread: http://forums.corvetteforum.com/c6-t...st-intake.html I went with the non ported and had good results, granted I do have a few more mods.

 

I got mine at Hinson Supercars (www.hinsonsupercars.com).

Excellent prices and great customer service.

 

PEAK SPEED-SHOP---a supporting vendor on this site has exactly what your looking for !!--in a couple of weeks I'm going to purchase their recipe--PEAK SPEED SHOP

 

Yep they ported my FAST and they did a great job and with great results.

 

Non ported sees about 12...ported is double that so yes its worth it.

I've ported over 100 of them and thats the source of my info.

 

While I have been on this forum, I have read many post about the outstanding quality of your work and the information that you provide. Due to those reasons, I feel that your posts hold more merit than most.

 

 

Am I remembering correctly that a ported FAST 90 is about the same in performance as a stock FAST 102? Do you know the gains from a ported FAST 90 to a ported FAST 102?

I ask because of all the vendor deals going on now with 102's but not sure if the investment is worth it having a ported FAST 90 already.

 

Do you need the air is the question.. stock cam and heads it sounds like .. right?
Do you even need a 102 in the first place ? Are you adding heads and cam ? What makes you want to swap the intake in the first place?
Port matching is always a good idea.. but if your not adding anything that demands more air...?

 

TimD38 bought 7 FASTs and tested them ported and unported on the same car at great expense. He had me port both 92s and 102s. The 92 outperformed everything fully ported by a few HP.

No its not worth getting a 102.

 

Interesting! Guess the velocity of the air is better on the 90's. Gotta love the forums; thanks for sharing.

 

Bolt-on only cars installing the ported FASTs all saw over 20+rwhp while stockers all saw about 12rw. I only posted results of tuners who dyno'ed the car with me out of the loop. Typical header cars with 380rwhp hit 400+rw after it was installed and retuned. DennisNJ50 saw a .3 ET and 3mph improvement with his bolt-on only cr that went 10.61 in the 1/4. JoeG reported the same gains. Cammed cars with 425rwhp (LS2) saw 450-455 with it installed. I've seen 30/34rw on strokers.

Tony Mamo duplicated all my results in his own testing to arrive at 12rw stock, 24ish ported. Cammed cars typically saw 27rwhp average.

High powered strokers saw as much as 40rwtq under the curve.

So it appears that even stock cars benefit from a ported FAST although you are correct in stating higher power cars with more airflow demand benefit more from the mod.

Here is a dno sheet for a bolt-on car from LG so I dont look like Im promoting my own agenda. The red line is a ported stock intake which made about 10 over stock. The blue line is a ported FAST which made about 9 past the ported stocker. The real issue with talking peak numbers is that it doesnt tell the real story. As you can see the FAST made way more power than the LS2 intake from 3500-5500rpm where the TQ was way more than the peak TQ numbers suggest. The FAST is a TQ monster gaining 25rwtq over a ported LS2 in that range.


So talking peak numbers the FAST bettered the ported LS2 by 9/14rw. Under the curve however the ported FAST beat it by 20/25rw. Now over stock? Forget it, the FAST was 30/27 on my best result at peak on a cammed car.

 

The 102 has better construction. Its heavier and modular.

The FAST 102 for the LS2 was an after thought though. They designed the LS3 102 and LS7 102 and then used the same casing as a basis for the LS2 102.

The 90/92 was designed for cathedral port heads and as such was perfected as the project objective.

 

The question to is was the hp gain just up top or across the board on an stock displacment bolt-on only car?

 

on my bolt/on car it was no less then 25 across the board

 

I dont think that graph was there before.... LOL

25 hp for just an intake swap is pretty good for just having headers and a cai

 

great people, fast service.

I added a SPINMONSTER ported 102 at the same time that I added ARH headers on my bolt on LS2 and the combination, tuned, gained 53/31 rw. As Spin said however, the torque gain realized between 2500 rpm and 5000 rpm is really significant and can really be felt.

 

"The 90/92 was designed for cathedral port heads and as such was perfected as the project objective."

--Did the 90/92 design initially had C6 clearance in its sight from the get go?

--Fast102 addressed the clearance necessary for C6 application without butchering and adding graft!?

--Even if Fast102 was an after thought for LS2, doesn't it benefits more by swapping Fast into LS2 than LS3 with basic bolt ons?

"The 102 has better construction. Its heavier and modular."

--With this attribute, wouldn't the new 102 better suited for boost application, especially without the graft necessitate on the 90/92 for C6?
