Dyno'd the cb7 today!

[91H22ACB7]

3" Intake tube with a Blox velocity stack
Horribly busted Megan header, bottom is badly dented in.
Gutted cat
Greddy SP2 exhaust
Intake butterflies removed
phearable.net basemap



For reference, for the 203 run, the axle back was unbolted and we closed up the plug gap. The only difference between the first runs was, 3rd first, then 4th second.

Wham!

203 is alot for the mods you have. Not bad!

Doesnt it matter what gear you have the car in when its on the dyno?

[HappyGilmore]

Deff not bad at all good sir!!!

[H311RA151N]

I’m not asking about the gear situation because I think you numbers are false BTW.

I’m asking you because you might know. You did after all just get your car dynod!

Also does that basemap make that much of a difference? I’m wondering because 203 is pretty damn good!

I second Hellraisin's questions, though I assume it does matter, because you say your first run was done in 3rd gear, and your second run was done in 4th gear. I assume this is a manual transmission then, with an F22A6 cam and intake but with the butterflies removed? What is the magic happening at 4750 RPM?

-- EDIT! --

Oh, I see now from your sig that this is probably your H22A swapped CB7: "1991 Accord Ex - H22A - Omnipower Coilovers - Greddy SP2", and that magic is your VTEC popping. Awesome. What ECU?

[SOHC-FTW]

I can show you a half a dozen well tuned bolt on H22a's over the 200whp mark, it's not uncommon at all.

3rd and 4th gear are common gears to do a pull in, most use 4th gear though.

Yes, that magic is vtec its running on a p28 ecu.
The first and second runs were back to back, and im sure you can see the difference. I think alot has to do with what amount of load the car sees.

Im planning to finish my header and redynoing in the hopefully near future, perhaps with a real tune vs a basemap.

[wed3k]

im going to believe the 2nd dyno because ive seen cams, injectors, aem intake, dc sports header, rsr exhaust hit 190 hp on dynapaks

[91H22ACB7]

Believe what you will.
No tom foolery here.

I think that dyno must be poorly calibrated. I know guys with a proper tune and cams on a healthy H22A that haven't broken 200. The dented cheapo Megan header, and that gutted cat (which provides a serious source of turbulence at high rpm... a restriction), and a generic tune... I don't see how that makes over 200whp unless the dyno wasn't properly calibrated. Even if you happened to have Type S or Euro R, I STILL don't think that those things would do it!

[Jarrett]

Properly calibrated or not, Dynojets read high. It's still impressive but on a Mustang you'd read closer to 180-185whp.

[SOHC-FTW]

Not saying all but ALOT have hit over the 200whp mark with decent I/H/E. Here's just a few from one tuner.... I could find 20+, but honestly a dyno is made for precise tuning, numbers will vary on any dyno and temperatures are not always the same.

^^This car latter made 260whp and went 11.6 on a completely stock block H22a, RLZ worked head and skunk2 pro1 cam's.

But like others have said a basemap and generic bolt on's i do not see it. Even though a dyno is only a tuning tool to begin with track numbers are the true test not horse power.

[wed3k]

any idea what the afrs were during the run?

[Mike1357]

I remember talking to Flatline back when he had this car and I'm almost positive he said that the motor had Eagle rods and pistons. With a decent basemap I think these numbers are completely believable. Also, depending on the day the dyno was done, there were two days where it was cold as shit down here so the cooler intake temperatures might've helped too.

Edit: I see you said today. Today was fucking high 50's. That's pretty damn cold to me.
