If all those runs on the graph are yours, how did you find 40hp @ VTEC xover?

Doesn't a DynoPack read about 12-15% higher compared to DynoJet?

Im just going to come out and say it vtecnuts, since you didnt catch the sarcasm. Theres no way you hit 235hp on that dyno with CTR cams. Todd did a test a while back on his fully built , sleeved GSR build, and with stock B16 cams, and better supporting mods than you, he managed 200hp. No way did you find 35hp with less supporting mods, and slightly more aggressive cams.

Looks like he also used snake oil that adds 20% more power than any other supporting mods.

OK, you probably have the record for highest hp on a 2 liter w/ CTR cams. Or any NA motor w/ CTR cams for that matter.

If you take a look at the Graphs closely it says *fly wheel HP, fly Wheel TQ*


if you take away 20% for drivetrain loss you get 188ish hp which would make alot more sense

although i don't wanna know how you get flywheel power from a chassis dyno lol..

logg frogg, it says flywheel hp and flywheel TQ, but thats because the software puts it there. The power on a dynapack is measured at the hubs, and usually reads 8-10% higher than a typical dynojet, like a 248C. Honda BVTEC drivetrain losses arent 20% by the way, more like 13-14%.

Icon4 Re: ***********b20vtec build and dyno graph*************

The motor really did put down those numbers and the cams sure did act like CTR/ITR cams. VTEC with the short ram was at 4450. We were able to drop VTEC to 4100 with the AEM ITR CAI.The blue line was with the customer's crappy short ram and dirty air filter. The yellow line was with the CAI. You can see that with the ITR ECU, VTEC at 5,700 was way too high. We picked up about 40 HP and 40 ft-lbs. of torque at 5,700 by dropping VTEC (as well as the fuel ignition tuning). Even Shawn was impressed with this motor.


Yes our dyno reads higher than a Dynojet, as it should. By bolting directly to the hubs the dyno eliminates tire/wheel inertia as well as alignment/tire pressure/strap down variables. An engine dyno reads even higher than the Dynapack, perhaps we should question the validity of engine dyno numbers...


Yes, Steve, I only made 212 with B16 cams on my 2 liter. But that was with a stock LS exhaust manifold, catalytic converter, and muffler IIRC.

Its.....

Surprising to say the least. Looking at the graph I would guess VTEC is at 5700 or so, but I would guess thats just the baseline. I remember you making 212, but you also had more motor, ported intake manifold and probably better headwork.

In any case, Todd has confirmed its genuine and this does look to be a special build. Congrats on the motor. With this strong of a baseline, you would be 'vtecnuts' not to drop some cams in there and spin it higher.

i do not have pics of the head work... and its using stock valves.. only the intake side was worked on. intake manifold is stock itr. not ported or matched ! i dont know about installing cams.. but maybe a oil cooler for road racing !
