Wondering if anyone has any results in gains on their H/C car... I have an LS6 intake, and am strongly considering switching to a FAST 102... I'd like to see some results though. Thanks.

Its a 92 to 102 swap

My setup is:
228r cam
TEA Stg. 2.5 5.3 heads
LS6 Intake
M6 w/ Monster Stg III clutch
Steel D/S
MWC Fab 9" w/ 3.90s
Pacesetter headers
TSP Y pipe w/ a bullet dumped
And I just put a cutout in like 2 days ago, no idea if the car picked up any w/ it.

Any guesses as to what my car would pick up?

Oh, and thanks for posting up Chris1313s results... That car gives me motivation lol.

By swapping your LS6 intake to stock FAST 102, I estimate a gain of 12-15 rwhp especially that you have CNC ported heads. With a ported 102, I think that you can reach a gain of 20-23 rwhp

Picking up 20rwhp would be amazing (and more than I expect). Now to sell my hotside (don't want to turbo the car anymore) and pick up the FAST.

How about instead of buying a new intake/tb/rails put that money towards a forged rotating assembly?
Its what I wish I would have done instead of spending 1500ish$ on a ported 102/92 rails setup.

You spray so it would give you some peace of mind and allow you to spray a larger shot. More reliable car and way more power than the intake is capable of allowing with not a WHOLE lot more money.

The car will be fine on a 150 shot for now. It was fine when I was spraying before, and if it does break, then I'll go bigger and better. I'm not spraying again until I get a new DD though, so for right now, a FAST is in the cards.

for the money of upgrading to a fast 102 intake and supporting parts you could almost do a ls 383 short block and gain more power.

I don't know how people compare the cost of FAST intake to the cost of a stroker that will cost 3K+ with installation and tuning !!

I'd try to get the most power out of my engine before going for a stroker.

how much is a ported fast installed and tuned by a good shop ?

IWGF

Not quite. You're looking at about 1k for machine work alone, plus the cost of the stroker kit, and if you don't know how to assemble a motor, there's the cost of that as well.

Me neither. I understand that going to a forged/stroked setup would be very nice, but I can't afford the downtime on the car right now.
That's kinda what I'm doing right now.

Not sure how much a ported one is. Installation at most shops generally is $80 per hr. That's a good average cost. Tuning, it all depends on who you go to. My tuner is only going to charge me dyno time, and I'll be doing the installation myself. Not like it's really that difficult.

i dont get any of you guys. Even if he did a stroker he would need a upgraded intake to get the moneys worth out of the stroker

If you buy new, with a few upgrades, it Is around 1700-1800 shipped for a rotating assembly.. almost exactly the price of a new fast setup. That Is with a new crank balanced and all.
You could most certainly piece together a new assembly for under 1500.
Add 800ish or so for machining.

So for an extra 700-1200$, depending on what you want and how you buy it, you have a forged 347.
My tune runs 200$ no matter what... And I would pull and install the motor myself.

I'm not arguing.. I put my idea and what I wish I would have done out there. It's not what you want and its not a big deal.

Not a 347..

how much hp does a 347 make over a 346?

How much reliable HP does a 347 on a shot make over a 346 on a shot?

breze84

Probably around 25whp...... What kind of power are you currently making with the LS6 intake????

98blueSScamaro

iTrader: (14)

Um very close to the same and the reliable hp is in the setup and tune. ask noz thats why he went 9.30's with a stock 346 and ls6 headed motor on a 200 shot and that was on a safe tune. and once again what ggod is a bigger motor if you dont have the lungs meaning heads and intake setup to support it.

I'm not suggesting a 383 build, I'm suggesting a 347.

I would much rather spray a 250 hit on a forged 347 than a stock 346, as would anybody. Especially since this Is his DD.

I'm fully aware of what stock block ls1s are doing on the jug. Tick just posted his stock short times up on a 250hit with a cam only motor, it could easily hit 5s@almost 120. However, a 347 would last a Hell of a lot longer than a 346 on any setup with a decent power adder, given same tune etc... It is forged.
Also we are talking sub 3k# cars as well, not street cars.

Roll your eyes all you want. It was my opinion. I think going to a fast 102 isn't the best next best mod for him and you don't think a rotating assembly is... So be it. I personally would rather want to spend am extra grand and reliably spray a 250-300 hit, the potential is way greater with that then it is with a fast 102 setup. I'm done now, you got my input.

I am still lost how we got on the spray...the original post said nothing about nitrous...

check out what tick just ram with a non optomial setup cam only with a glide 6.05 in the 1/8th

obviously a 347 is going to be more reliable but you pay for that plus I would take a good *** tuner/ nitrous on a 346 over Joe nitrous junky on a 347 anyday of the week...I have seen plently of holes in 347s and only on a 200 shot...
