first time to ever break a bone -- very painful and slow to recover -- but doing much better now

last time i fell on my dirt bike (or off any motorcycle) wan when i was 15.

i have been riding this trail on the same bike since 1991.

just a dumb luck thing -- my knobby tire slid on the grass and i was thrown onto my right shoulder --it was in fact the slowest part of the 2 mile loop out there on the ATV trail right b4 the hill climb i do in 1st gear-- i did a downshift a bit earlier than usual and hit some slick grass and that was all it took to allow the rear tire to slid abt a foot or two and then when it grabbed it shot me off the trail and off the bike-- it was a very fast and i took a bad fall on the right shoulder and snapped the bone --

hard to lift up the bike and ride it home but i did it.

i hope to be able to shift and drive the vette in another few weeks or so

Of course we believe you Brian.

Hans,

Go to the performance page and check out your torque #s vs others....the combo of CATS and resonator must be choking the car....the #s for your car equal that of cars in the 380-400hp range.

That 370rwtq # for Hans looks suspicious to me. Pete has 400.
What does the AFR look like? Anybody want to post a dyno run graph?
Sorry Pete didn't put his on the dyno, then we'd have a benchmark for the dyno that was being used.

Dyno seemed pretty conservative.......I talked to one of the guys at Vals, he said they tend to be alittle on the tough side with the #s.

I think the resonators hurt you, tf95ZR1, said he picked up some decent numbers when he dropped his Borla.

I'm skeptical of the torque number. JMO.

Hans car peaked at 6500RPM, seems alittle low.....might be more of a case of the car being capable of more HP.....30 extra lbft is alot relative to the hp #s......pleanty of people making 380-400hp with 370lbft. Would like to see Hans run a more free exhaust(get earplugs).....the cams Pete is running and the wide variance in cam timing from car to car could be doing it also.

My car dyno'd 385rwhp and 350rwtq. That's one reason why I'm skeptical.
And 30lbft less than Pete is another.
Hans is running the LT-4 resonator, which isn't bad according to Marc H.
Also an Xpipe IIRC.

[LGAFF]

Look at the performance #s page, almost every car is within 2-5% of the HP rating.....those with cams show a large spread from HP to Torque.

402368Vette Doctors Top End Job, Watson Headers, Desert Development Exhaust, 4.09 gears, Jeal cams.

475411DRM-385ci stroker w/special Rippie Race cams, Geoff Jeal Headers, 4.09, Tri-Flow exhaust.

Even the factory ratig is 375hp and 370TRq at the flywheel.

Hans hit 370rwhp and 370rwtq

KarterDon hit 360rwhp with just a ported plenum and catback....


We also found out Bob HDZ, who has #88 1990 has a federal emissions exemption sticker on his hood...hmmmmmm

You said rear wheel torque. That's 440+ at the crank. A 70lbft increase??
