Actually, it’s a 4c not a 5c. I mistyped.

No way a 18 mani is picking up over 50 hp vs a GT350 mani.

Geezus people are drinking the 18 koolaide.
Read the mod list again... carefully.

An 18 manifold would be a nice upgrade over his existing manifold, however, not 50whp.

Where'd you get this dyno'd? With an e85 tune and 18 mani, you would be making 450/400 probably for less than a grand extra.
It would probably bump it to 420-430. E85 won't make that much of a difference either, 5-8whp or so.

Just saw he still had his cats as well. 450 would probably be stretching it but we've seen a few catless long tubes + 18 mani + CAI + E85 tune cars hit 450 wheel.

I think the dyno he was on might be a bit harsh but I would venture to guess:

+10-15 from e85 race tune
+15-20 from 18 mani
+5-10 if he were catless

Alec, I dynoed at Motorsport Technologies in Houston. From what I've researched I would expect about a 20-25 rear wheel gain with the 2018 manifold, 47# injectors, and E85 tune, putting me at 410-415 rear wheel SAE through cats. and about 10 rear wheel higher if measured by STD. What matters most to me is how I'll run at the track, hoping for some mid 11's at 115 mph+ on drag radials. Anything faster would be a gift.

Fair enough. Do you have a torque converter? Mid 11s is pretty quick. High 11s would still be pretty solid imo.

It might be wishful thinking. Ran a 12.6 stock on Firestone Firehawk radials, hoping the extra power and drag radials and lighter wheels will be enough, don't plan on doing a converter.

I met a gentleman at Carlisle that did 455whp on VMP's dyno that day. He was running catless longtubes, 18 manifold, Airraid intake, Lund tune and 93. Car trapped 119mph a couple of weeks ago to back up the dyno.

Just goes to show how different dynos are. It seems like the dyno you were on, for example, is ~25 whp lower than the typical dyno. Did you gather stock numbers? Wouldn't be surprised to see you around 350 if you used the same dyno and they hadn't calibrated it between then and the run for your current numbers.

I have similar mods as you and dynod 367/327 stock and 447/376 post mods. From what I've seen, that's about 10 hp less and 20 ftlb less than a typical dyno, which makes sense for both runs.

Moral of the story...it's just a number.

Regardless, I do like that trap speed. What are the FBO 18 A10s trapping at?

Depends on the dyno. However, pump e85 will not gain 10-15 whp on a FBO car, like previously mentioned. All other numbers are accurate.

However, numbers are irrelevant.

I included the gains he’d get from the tune as well since he’s on the box sct tune.

Also those trap times are crazy for the 18s lol. Can a cj fbo 15-17 even hit that?

Touche, I'll give you that. Probably a little more left in the calibration.

Yes, they are very quick, its the 10r80, such a good transmission. It is hard for them to trap that high. They need weight reduction and proper fuel.

I am no dyno expert or anything, but I do wonder why mine made more tq than yours, but less HP? Is it just calibration difference or ? I was always under the impression the HP figure was calculated off the TQ reading. Again, not a dyno expert by any means at all.
