I don't see how he could have much more than a GT30 back there.

thebarber · 05-13-2012, 01:49 PM

455whp at 8300rpm = 288wtq at 8300rpm

501whp at 8300rpm = 317wtq at 8300rpm

When peak HP is at such high rpm, you don't need to make a ton of tq up high (relative to HP, that is)

My vibe's 2zzge is 180hp at like 7600rpm and 130tq at 6800rpm...

3rd gear would have been cheating anyway.

tooter · 07-07-2012, 02:54 PM

Does third gear record a different horsepower number? If it does, I only want accurate numbers, not pumped up ones. The 4th gear pulls took so l-o-n-g and the engine barely made it up to redline, I was laughing!

IN N/A Cars i do no but in F/I cars there are some differences in WHP.

BEEF · 07-07-2012, 02:53 PM

Isn't 4th gear 1:1? isn't that the best power transfer?

You can tell from the video that it took so long to wind out the engine I thought it wasn't going to make it up to redline.

I don't think that Harry believed it would make it either. He said that most dyno runs are about 8 seconds. Mine were over 30 seconds.

cali yaris · 07-07-2012, 04:05 PM

yep, 8-10 sounds about right.

I was always under the impression that 4th gear pulls were standard for dyno. Not sure why though.

Maybe it's because 4th is usually 1 to 1 gearing like BEEF said. It just was so funny how long it took to wind up because the little engine doesn't make much power.

lol yeah did you have to pay the tech overtime so he could finish the pull lol

Yeah, the engine was still trying to hit redline when Harry told the guys to close up the shop and go home... he'd stay overnight hoping the run would be done by sunup.

cali yaris · 07-07-2012, 07:06 PM

1 to 1 is the most accurate, and the pull is long enough to record with precision -- in tooter's case, great precision.

The pull above on mine was to 7300 rpm, 1000 over where the stock limiter kicks in.

Yeah, the computer had plenty to time to record every nuance of power fluctuation in infinite detail.

Harry, the owner was very kind, patient, and helpful as we spent quite a bit of time talking about the principles governing intake manifolds.

I left his dyno shop more educated than when I arrived.

cali yaris · 07-07-2012, 10:58 PM

you're funny, tooter

why? · 07-07-2012, 11:30 PM

Tooter, some pulleys and lightweight wheels would make that less painful, and add a couple hp to get over 100 as well.

tooter · 07-08-2012, 12:36 AM

There's no pain in getting an honest accurate measurement of the power that the engine actually produces.

The point isn't to enhance the results but to obtain two relative results where the intake manifold is the only change.

And that heavy pully on the front does serve a purpose. They used to be called harmonic balancers. The flywheel weight on the front helps to minimize the twisting forces exerted on the crankshaft by the flywheel weight on the rear.

I visited the CNC guys today and we went over details and clearances using the 3D image generation of the flange. The intake manifold flange will have a small 3mm deep inset where the runners of the manifold can be inserted to hold them in proper position while they're being welded on. The thickness of the shelf will match the thickness of the runner tubing so that the interior remains uniform. Any slight imperfections I can smooth out from the inside with a Dremel. The computer automatically generates a seamless transition within the one inch thick flange between the intake runners on the Corolla manifold and the intake ports of the Yaris head.
