Well done.

Nice linear power curve!

And that's on an otherwise STOCK SR20VE?

With further tuning, i.e. correct the rich mixtures, you should get a few more WkWs., and probably more torque through the 'driving' areas.

Seems those Franklins DO work! And only stage 2's, that got more than a well tuned SR20VE with SR1600VE cams with the same mods on the same dyno.

What's next for your mod list?

Nice power gains.

I little off topic. But, anyone been doing Franklin Stage 4 cam dyno runs? I'd like to get a set of those.

I honestly don't think their dynos read the same as ours. It was the same thing when I lived in South Africa. You could probably pick up some hp though. Maybe cam gears? It still looks healthy.

BINGO!

You've hit the nail directly on the head!

For some reason the Dyno that is used in Auckland, New Zealand (as this one was) for most of the figures quoted reads low; especially when compared to the American dyno figures, it's a fact.

FYI a standard SR20VE with manual conversion (converted from CVT), with 2.5" mandrel bent exhaust, and custom intake with K&N pod got 111WkW only moments later.

The thing to remember here is that it's NOT the peak HP numbers, it really is ONLY for comparitive reasons.
Let's look at it this way 111WkWs versus 130WkWs for similar set-ups, that's an extra 19WkWs, which is a lot in anyones language.

So I understand that it SEEMS low, but please look at it in a comparitive way.

That and the fact that these are stage 2 cams, NOT stage 4's. They're kinda similar in spec to the SR16VE cams but in the experiences we've had here, they're easier to tune and offer a much smoother power curve and better low down torque, mostly because they're designed specifically for a pretty stock 2L and not a little 1600.
Good work Aaron!

And there's THAT fact as well...

I'd taken the liberty of expecting that the description at the bottom of the post would have explained that, but good point!
Maybe that could be the confusion here?

I'd LOOOOVE an extra 19WkWs please!

Those are good numbers; comparing them to Clint's numbers.

The air fuel ratio needs some cleaning up. With the right afr, the power band could be extended.

yep we will be fiddling with the AF this week

the power was made surprisingly early in the rev range. 130wkw @ 7000 rpm is perfect for me because i dont particularly like revving my car out.

in fact when we adjust the AF ill be bringing my redline down from 8500 to 8000

Aaron's got some damn fine numbers there & made his goal WHP which is awesome. He deserves it too 'cause he's one of the nicest fellas you could meet & put a lot of thought into his transplant.

can we see a dyno with the original stock cams, or a set of 16cams maybe, so we have a better understanding of how great these cams really are??

It's not really a case of 'how great these are', I just hope that you're not being condescending; but more a case of a VERY happy owner / driver on a budget that WORKED!

I can rustle up some graphs from both the car that followed (111WkWs) AND a car with exactly what you have asked 1600cams and the same mods as Aarons.

It was basically THE 'pretty-much-stock-plus-cams' car to beat, till now.

Even though it was sold lately, I'm sure that the new owner won't be too upset if we post the figures here.

A car with stock SR20VE cams on the day dyno'd 111kW, the car with Franklin Stage 2's dyno'd 130kW (same dyno, same day). The stage 2's are listed as a "mild street" cam so they're not as big as the N1's and they don't even come close to the stage 4's. I know you guys wouldn't be that interested in the stage 2's as it'd be more cost effective to go for SR16VE cams. It was more designed for people like Aaron, for a bit of extra power without going overboard for the local market.

I can't wait to get my SR20VE with stage 4's into the pulsar. That's gonna be a sure sign of how these cams perform.

thank you for the comparison, but i would really like to see a dyno of the same car before and after... here is my before with stock cams and after 16 http://www.sr20forum.com/sr20ve-sr16...sr16-cams.html
