I went to a car show on Saturday and at the show they had a dyno. I've been curious what my car was putting out since I got it together and worked out most of the kinks so I went home, retrieved it and made a run.

Bottom line 250 rhwp @ ~4100 rpm and 375 rwtq @ ~3250 rpm

Engine Specs:
406 SBC, rebuilder dished pistons, assuming ~9:1 compression
Holley 750 CFM Vac. Sec.
Comp 268H 12-210-2, 218/218, 0.484/.484 (1.6 Roller Rockers)
Promaxx 2180 heads, 64cc chamber, 190cc intake runner
Summit 226010 intake (Weiand Speed Warrior copy)
Hedman 68460 headers into 2.5" dual exhaust w/ Dynomax muffler
36 deg total timing


The dyno sheet they provided doesn't have RPM's. I pulled into it into a plot digitizer and backed out some data points which you can see In the Excel sheet. I know there are no AFRs given but I can say at WOT it's around 13-12.5. I don't think it's perfect there yet but this was a spur of the moment thing.

 

Dynojet has the worst rep for accuracy. Use it for a tuning tool only. The spreadsheet power curve looks correct in shape for that cam though numbers look low while the torque numbers look ok.

Ill guess thats a fun car to drive and wheel spin is a problem. Just remember no one races on the dyno.

 

I agree. I thought HP was low as well. Torque not as much. I need to get to the track. The one time I made it with my car this year they had canceled test and tune.

It's definitely fun to drive.

Here's a vid of the run. For some reason I can't get the video to embed. Here's the link.

See what it runs but its a mild combo. Would have thought it would make alittle more than that but it is a small cam and intake

 

That's the plan. Hopefully I can make it out next Sunday.
