Fast 102 vs Super Victor Ive Got a 408 in a 3360 lbs Formula. Trick Flow 225s built by T.E.A. 13 to 1 compression. Cam is a 248/254.612/622 lift,113 lsa. Turbo 350 with a 4400 stall. 4.10 gear and 28" slicks. Fast 90/90 with a Nitrous Outlet plate system spraying 150 shot. Track only car.
I am thinking about going to a Fast 102/102. Or a Super Victor with an elbow and a 92 TB. I havent cut the cowl yet.Will stay with the nitrous outlet plate system if i can. Dont plan to spray much over th 150.Will spin the motor up to 7500.
Any input is appreciated
Thanks
Roger

When it comes to N/A or the bottle I would never run a carb style intake with an elbow.... just about everyone will tell you that elbow will not help the combo....... The only way I would go is a 4 barrel throttle body like from Accufab mounted on top.
Like said above YB will get you the best answers..... that is were I learned the above from.

I am currently running a mildly ported FAST 92 on my 416 - hp flatlines from 5,700 to 6,450 rpm. I know its not the 102 on there, but I have ordered the super vic. No elbow tho - just to give you my opinion/direction. From the sounds of your combo, it would love the super vic with a 4150 tb.

Exactly what I was going to say.

Yea, we see the same flatlline on mine. So with the 4150 tb, you will have to go to a speed density tune. Is that correct?

Yes. I used to be on there all the time but work blocked it......... I wonder why haha.
IT said sites are blocked automaticly by a company they pay when sites are reported to them as having bad content, viruses ect ect....... IE RICK ROLL haha.
The way I understand it is that when the air flow has to make the turn in the elbow it really kills it. With the TB air gets pulled in and goes straight down into the intake and works with the VAC from the engine. Air does not really like making sharp bends..... there are pictures out there that show you, in short a lot of it hits the back wall and gets stired up/slowed down. The less bends the air flow has to take the better/the easier the air can get pulled in with less turns the better.
Im sure someone can explain it better but that was the consensus on YB.

I run a ultra low elbow,holley 90mmtb, GMPP L92 intake. L92's on a stock short block 6.0L. dynoed 6xx at the flywheel, and rev's 7700+, peaks at 7300. cam specs are 242/246
The gain going to a 4150 TB, was not worth cutting up the cowl/hood on my SS. Gains at most were 10-15hp on peak.
cars been 10.93 at 126, 3800lb 6 speed car, 1.44 60ft.
so I wouldn't fully say a elbow is "junk" but I think I reached the limit of what the GMPP L92 intake can handle. going to do more dyno tests with a vic jr l92 intake with the elbow compared to the 4150 tb. and might also try a slighty larger camshaft as I think it can make a little more power yet...

Did you do a re-tune with the testing? I am curious what the gains would be with another tune if no.
Sometimes there is more work that can be done to those TB's
for example I had a big Holley twin like a 58 for my LT1 car that I had and had it worked on some more... even had the ends of the screws holding the blades in ground down.... Never got a chance to try it out. There are some impressive carb's/TB's out there if you know were to look....

Otherwise, I think your best bet is to go with an elbow (do your research before selecting) w/ direct port. I am pretty sure you'll be losing more than 15hp over a 4150 tb based on all the results I've seen, but it should still pull past 7,000 - I dont think the FAST will do that for your combo. Purely opinion tho, so take it with a grain of salt

Thanks everyone,
All good info. I will go with a super victor and 4150 tb.If the wallet allows I will do a cam change. That combo was originally a street/track setup. We decided to start playing with a speed density tune, that is the reason I was looking at the elbow. So I could keep the maf sensor.
Thanks again,
Roger
