289 DynoJet results

170 RWHP@4600 218RWTQ@3200

Not bad for a fairly stock 289, V4, C4 auto w/2:80 gears. The engine has been rebuilt with an '86 roller block, E303 roller cam and rockers, 1.84/1.55 valves, stock ported exhaust manifolds and heads. Intake ports mainly stock, although I did do a little intake bowl work. Pertonix II, Flame Thrower coil and elect. fan Edlebrock carb and intake manifold

That's the kind of performance I'm shooting for with my 289, although I'll be happy with anything over 150 RWHP.
Rebuild 289 with .020'" Speed Pro hypereutectic pistons, 204/214@0.50 cam, roller tip rockers, cleaned up stock '67 289 heads (stock valve size, exhaust-side and bowls cleaned up), windage tray, stock intake with 4300 Ponycarb, tri-y headers into dual 2"stock style exhausts, pertronix ignitor, coil and wires, recurved distr, stock C4.
I hope to get the car on the dyno later this year.

BTW, most links on homepage don't work for me.

True, My web pages are not updated. I'll try to get them updated.

FM was a source of great info regarding home porting my heads, which I highly recommend. Porting heads is an art and science, but when done right the benefits are well worth it. My port job required many hours and many dremel bits, as well as being dirty, dirty job. But the torque curves were very flat from about 2500 to 4500, indicating good VE.

My dyno guy was able to put all the dyno pulls data on a CD. I needed to go to www.dynojet.com and download a small reader file. But then I had all the data, torque, HP, air fuel ratios right on my PC.
Good Luck

Give the spamming a rest, will ya.

I hate to be the one to tell you this, but your numbers are not correct.

There is plenty of info around showing the differences between dynos and how they compute power output.

Do your homework before spouting off. [img]/phpBB/images/smiles/icon_frown.gif[/img]

I'm well aware of the differences in dynos and how they measure output.

Your percentages are incorrect.

The fact that the MD shows lower numbers at the wheels is pretty common knowledge. For that matter so does Superflow.

On average that difference is not more than about 8%. Maybe 10% tops depending on the variables.

That is assuming a competent operator and a well calibrated dyno of course.

If your dyno is consistantly 15-20% lower than all the Dynojets, as you implied, than I suggest you need a calibration or a better operator.

That is not to bad at all for the mild mdifications made. A few more and you will be over 200 easy. Good to see another Pacific Northwesterner on the board. If you ever need any leads or assistance let me know.
