Spun the rollers down at Hybrid to the tune of:

**Pure Stock** · 09-23-2007, 03:57 AM

Just a little recap:

Stock N/A aspirated 302 short block. Static compression is a kill the torque 9.0:1. A pair of Twisted Wedge cylinders heads are bolted on top of the circa 1993 short block. A hydraulic roller cam carefully selected to work with the non-flycut hypereutectic slugs keeps the valve events just so. A long runner EFI Holley SMII feeds the TFS's the atmospheric intake charge.

A battery of combinations and small tweaks were employed throughout the 17 dyno pulls. The highest peak numbers were generated on the final pull.

374.3 RWHP and 362 TQ were produced

Big thanks to Killercanary(Paul), Yeloh95(Troy), Eric@Hybridynamics, and cam303(Chris) for the extra hands.

New E.T.'s to arrive.

Joe, thats amazing!!! Very nice!!

**gmkillr** · 09-23-2007, 10:15 AM

Awesome man!!!

374 rwhp out of a stock 302 bottom end!!!!!
That is amazing!!!

I bet this gain in power could get you into the low 10.60's or maybe even the
high 10.50's at 125-126mph!!
Awesome man!!
You must be very happy!!!

Congrats!!!!!!!!

**went9s** · 09-23-2007, 10:36 AM

WTG Joe! I haven't had a chance to pull the video from my camera yet, but as soon as I do I'll send it to you. Thanks for letting us come down and hang out! I can't wait to see what this thing will do at Cecil this year!!!

Are those rear wheel numbers? Corrected?

I need to get mine on a dyno at some point.

i had a great time joe ,glad i could help with the new "parts" install. i'm glad it picked up and those are great numbers , bob i think they are std. numbers ???if you dyno yours let me know i'll come over

**coralcoupe1993** · 09-23-2007, 12:32 PM

Nice! Sorry I didnt go with ya man!

**Slow01GT** · 09-23-2007, 01:15 PM

**Cam99** · 09-24-2007, 12:20 AM

Great numbers

**somethingclever** · 09-24-2007, 09:11 AM

Nice!!

Did the area under the curve change much?

With a really lucky pass you might go 12's!!!!

The dyno flog before the most recent one generated 360 to the wheels. The best e.t. up to this point is a 10.71. With the new found power we hope to get back to what we were able to run or realize a slight improvement.

Yes those are rear wheel values. They are not SAE(corrected) The correction factor is STD(conditions present at the time of the pull) Not sure why they call it a correction factor at all. From what was expained to me, it is the current temp, barometer, and humidity present when that pull was executed.

It picked up power from the moment I matted it to the point I clutched it

There were some points in the graph where there was 20+ RWHP gained.

12's or bust.

**somethingclever** · 09-24-2007, 10:14 AM

Excellent!!!

What was peak rpm/tq? (did they change from previous)

You added stepped tube headers, correct? What else?

The correction factors (STD vs SAE) correct to different temps IIRC...basically there is roughly 3% difference between the two. (SAE being lower)
