AFR 215 Preliminary Dyno #'s C5 Corvette Auto with a Stall
Have a 2001 C5 Automatic. Still don't have car back as they were tuning it again. Revamped my Dual Nozzle set up for a simplified PLATE System. Had car 3 months as the AFR's took 8 weeks and had to wait for a few other things.
Installed a Bigger Cam, (234/240 .598/.608 114LSA), upgraded to #42lb Ford Injectors (flow more on a Vette), an in-tank walbro fuel pump, AFR 215 Heads (Replaced Patriots). Also have a new air filter so she would breath OK. Other Mods include NO CATS, ZO6 Titanium Exhaust, KOOKS Long Tube Headers, Porter Shaner 78 mm TB, UD Pulley, ls6 intake (stock on an 01 C5)
The car sat for a long time and this dynoing was immediately after install so it might take time for the car to learn the new set up??
Tuner took out 4 degrees of timing since I am running a 100 Wet Shot. Haven't done a final tune and to remind everyone. I have an Automatic with 3.42 gears, and a decent size stall (Yank SS3600 Torque Converter) and ALSO TO NOTE, (dynoed Car unlocked) Plus, I am in TEXAS and it was 100+ degrees out when they dynoed it just to make sure all was working not to try to get the highest numbers.
I haven't gotten final numbers (or saw a graph or got TQ Numbers) but the they told me 390 RWHP on a N/A Tune and 480 RWHP on the Nitrous Tune (pulling 4 degrees) shooting 100 shot through Nitro Dave’s Plate.
Since they dynoed 390 on a NA Tune, then pulled timing, I probably picked up 100 RWHP on my 100 wet shot because if they would have used the nitrous tune the numbers would have likely been below 390.
Are these Numbers Super Low??? I thought so, but they said an Auto with a big stall doesn't dyno that great, bring it to the track. I am sure when it is cool it will do much better. Will get her back in a day or two after he does some drivability tuning.
Anyway, what do you think? Should I worry or just wait and see? I will post actual DYNO with TQ, A/F, etc etc

Numbers do seem low but was this unlocked? Also if you post your graph when you get it that will help. Hopefully one of the mods will move this to the dyno section.

I was going to look at a FAST, but was told by several that it wasn't worth the money. I mean I would have had to get the Fast 102, then a Bigger 102 TB, then my nitrous set up currently on there wasn't going to fit right. Got a used 78MM polished Nitrous Outlet Plate for $125 so went with that.
I might get that one day, but already spent Way more than I wanted to 1,700$ or so (just off top of my head) and I was told I might get 15-20??
Again, doesn a high stall (or 3600 stall) converter unlocked, combined with 100+ degree heat in an automatic with the Car just sitting stationary on the dyno with no real air flow liek normally would come from my Vortex Air Intake have anything to do with the low numbers?
I DO think ALL the facotrs I mentioned have to play a big factor in the dyno. Hell, how much would I gain just by locking the converter?????? I am asking, I don't know???

If you locked the converter I'd say you'd gain maybe 10-15 rwhp. As far as the FAST intake goes, its give and take really. The LS6 flows well, but if you've got big air craving heads like the new AFR 215's maybe down the road like you said upgrade. You don't "need" the 102 either. A used ported Fast 92 would be fine. Take it to the track and see what happens. Nothing like beating a sub 500rwhp car with a lot less showing on your own dyno sheet

Thanks DJ. I should definately feel the difference I mean the Heads are WAy better and the Cam is bigger.
I ran 11.42 at 123 MPH with my old combo 228/228 .588/.588 114LSA Patriot Heads(that might have been with a Yank SS4000) went back n forth during a Tranny change and 7.15 at 94.55 Mph the 1/8th. Was using BFG Drag Radials. I had nitrous but it was never set up right, but 4 years ago hit it at Ennis once and got 11.19 just trying it on one run and I didn 't know how to set it up perfect. I have to look at the slip for the MPH.
I haven't been to the track in 2 years, but will go check it out soon when it is cooler! I said all that to say that my car ran that well before with not the best heads and a smaller cam. I know everything needs to work well in combination.
I actually called AFR and told them my Mods and they reccomended the 215 based on my Mods.

I know it's a lot of money, but you better do something with that intake. Everything else looks good though.
My 205's with 231/236 cam did 441rwhp (on a very humid day)through an unlocked 3800 stall and 3.73 gears which eat up a little more hp. And I still don't think my numbers are anything special.
You should have more there with those 215's and G5X2

I wouldnt worry about the dyno number to much my car only made 400rwhp which i thought was low for the mods but it feels much faster then that. I ran a pretty good time considering i had bolding street tires, shitty stall, and crappy 60ft. So to me track numbers tell the reall story now i just need a 3600 and some tires lol

The FAST setup isn't as expensive as you would think especially when you consider the fact that you've got a used LS6 intake and ported TB to sell.
Used 90 or 92 intake = $600
LS2 TB new = $300, total for both = $900.
Recoup $400 for your LS6 intake and TB and now you're only out $500. That's how I justified buying mine!

Yeah I was looking at the 102, BUT then I also hve the get a New Nitrous Plate since mine is a 78MM. I will see how things pan out first before I get too worried, BUT that is an easy Mod to add later.
Thanks, but still can't understand why it is at 390?
Also, frito, what does YOUR car run on the motor in the 1/4 mile? I ask this just as a gauge because I knwo what I used to run, or ran in the past 11.42 at 123MPH and my car wasn't as good as it will be now.

just run it at the track and see what happenns there is no doubt there is a huge restriction on the intake side, put it this way when i had my FAST 90/90 outta the box on my 402 i thought it was perfect ran 11.13 at 123 and was slightly spinning due to old slicks i picked up for nothing, well i was bored pulled my intake ported it and droped to a 10.93 at 127?? After i corrected the AFR again. JUst drive it!! when you get the money to upgrade do it.
