Pretty nice numbers for a stocker.

True, Bob. I think he's referring to peak values, w/o regard to rpm - gave me pause as well, till I scrutinized the graph a bit. The trace with the highest torque also tails off more than the others, resulting in less hp at the peak hp point...is all.

Congrats,

I'd say you have one of the better performing stockers out there. My current car, 1991 #473, dynoed at 329HP, 321 TQ at the wheels in Portland 2 years ago. It was bone stock then. My chart looked very similar to yours too.

I never dynoed my 1st ZR-1, #458, but it would walk away from this one. It's currently located in McAllen, TX owned by mgbrv8.

Yea I promised myself to do as many dyno runs as possible so I could guage how much my car was improving with every performance mod. Next week, i am going back to the dyno to see how much the car improves with a Haibeck chip and x-pipe

on your pipe size . jmho, but on a stk car ,even a car that has ported inj housings and plenum,headers fidanza flywheel and 410 gears .i believe that a well done 21/2 in give one better all around performance . you dont lose low end and its frre enough for my car to dyno 409.9 rwhp and 373.66 tq and that was with the flowmaster cat back system cars best mile an hr at the strip with this set up was117.80. had dr gas make me a 21/2in system with his xpipe and spin tec mufflers and the mile an hr went to 119.85. both of these runs were in july snd the temp wa around 90-95 deg . nacho corey could port your injector housings and plenum just like he did my black car for around 1500 or less inc r and r. the real roting cost is when you do the heads as the mototr has/or should come out to get the the heads off,ported and put on . you will have your mind blown by the power thats set free,by just porting the inj housings and plenum . when you go to see him ask him to pull up my dyno sheet for you to see what you aprox would end up with . i havent dynod the car with the newer muffler x pipe set up. but with a 2 mile an hr increase at the strip, id be will to be the car makes at least 15 rwhp more than with the flow master set up . just think how much more fun the car would be with 70-80 wrhp under your foot . you end up with what we call the perma grin
