I looked at the intake and a 1000 cfm Holley TB last night at Billingsly's shop. I can not see ho this setup can not beat a Fast 90. The runners are a straight shot to the head and there is a lot a material to work with.
Hey 4thgen, sounds like you are on a similar path. We should get together and see what's up as we are close. I am going to call Larry today and discuss this.

I installed a EGT system for each primarn to see what was going on. I found that spraying through that manifold yeilded me a 250 degree difference is some of the cylinders. Then we switched
GM carb manifold
Got hotter and made less through the whole curve. It did go alittle slower and lost a mph or 2 but when we sprayed it with a plate it worked like a champ. EGTs were within 50 degrees of each other. Never took out another plug.
What I am saying is that if you are a max effort small cube motor that is going to be running on motor then the 90/90 is a better combo but if you are going to spray the car that the carb style is way way better.
I have the same intake on my car 5.82@121 in the 1/8

5.8 anything I wouldn't consider disappointing results. I don't know about you 2 guys but that seems to be pretty fast around here. I was just giving the differences that I saw in the 2 setups. With the 90/90 and a SHO nozzle the car went 5.90@119 with a 1.27 60ft. This was on a 28/10.5W. We switched to a little 28/11.5 ET Street for the TTT5 true street class, at the same time we went with the carb style intake and a plate. We went a 6.07@117 with a 1.37 60ft with 200 pills in the plate. This by the way was in a 3290lb TA with a hydrolic roller 11.5cr iron 408 with 241 heads.
My car went a 5.82@121 with a 1.30 60ft with a solid roller 13.0cr iron 408 with a 241 heads that weighed in at 3300+lbs. This had a acufab TB on a GM carb style intake with a compucar plate pilled at 300. Now it has a Nasty sheetmedal intake with a dual stage fogger and a 105mm TB. I am in the process of getting some ETP 255 heads. We will see how fast it goes but according to you guys it will probably just be disappointing again.

But it's not disappointing in the least, CJ is talking about my car. The engine is a high compression 408 CID forged hydraulic roller. We had a FAST 90/90 and a single NX SHO nozzle on it with a 300 shot and it ran faster times than the GMPP carbed style with the Compucar plate and Wilson carbed style T/B has yet. Using the EGT probes and data logging on each pass we can tell that the carb flows more consistantly to each cylinder than does the FAST 90/90 and the carbed style set up is alot easier on the engine parts. With the 90/90 it blew the head gaskets twice and fire spotted the DS head once. The sheetmetal cowling at the base of the windshield does have to be removed to use this set up though, I cut it out by hand using a small hand held hack saw and saved it so I could weld it back in if necessary. We have also noticed that the carbed style manifold does lose below 5000 RPM but really comes alive above 5000 RPM, I shift at 7000 RPM. We had the car running pretty rich on the big shot so with some tuning we will get back what we lost. You also have to remember that the 5.90 pass was on a 10.5W tire where the 6.0's have been on a 10.5 ET Street.

ok, now that we have ALL the details, I would say that is not dissapointing at all
looks to be quite a bit better than the 90/90. would be really nice to have back to back comparisions though

I have the BS3 and the Red Alert EGT probes on each cylinder, we moniter everything the car is doing while it's going down the track. We had a very conservative tune in it running consistant 6.0/6.1 passes on the little ET Streets and a 200 shot. We still have quite a bit of room to tune it for more power at the correct times.

The 90/90 was eating so many plugs and even blew a chunk out of the head like a cutting torch. The carb style hasn't taken one plug out and is running so much smoother. Like I said above though. If you are going to run motor the do the 90/90 but if you are going to spray the car with anything over 150 then do the carb style.

What about a BIG CI all motor setup.. 440+ CI, max effort pump gas motor? I'm planning (hoping) to make 700 rw when the new motor's done in a year or 2, for all I know, somethingelse may come out before then, but at this point, I'm planning a world bloc, ls7/ET265 heads, maybe spayed valve ones if they continue the work on those, 1 7/8 to 2 inch stepped headers w/ HVMC, the works. and I wanna go as big on the CI as I can leaving enough room for some rebuilds on the cylinder walls... hopefully it will end up in the 470 ci range when I'm done.... way I figure, the fast intake will most likly be a restriction. If anyone has tried this intake on a really big CI motor, or a max n/a setup I'd be most intrested in these findings... I understand the concerns with spraying, the even air distribution of the intake is worth it's weight in gold for that IMO, if I were planning on a spray setup, I'd take this route regardless of any losses on motor, drivability etc simply because of the safety of the design.

Yes they would be with correct tuning using the BS3 for timing and A/F. As Sux2BU said thought my car is set up to run True 10.5 True Street class and we can't use a direct port set up.
