1st time at the dyno
85 corvette. Great fun. However I feel out of place with these numbers compared to most everybody else's:
213.5 HP @ 4250
307.6 lb/ft @ 3250 mods listed below:
Fastchip, TPIS pulleys-cat-back ex.-AFPR-plug wires, accel 24# injectors & super coil, ported plenum, MSD ignition, airfoil, Bosch +4s, descreened MAF, power coupler, MAT relocate,SLP CAI,air pump elim
What are some opinions on the numbers? I have EM longtubes waiting to be installed. How much will the numbers improve? :seeya :steering:

Re: 1st time at the dyno (88BlackZ-51)
=around 250/350 from the crank which aren't bad numbers for those little mods!
isn't your motor rated at 230/330?
did u notice a performance difference with the chip, or the catback?

Re: 1st time at the dyno (jmrl98)
Those number suggest you are pushing about 250/360 at the crank so you definately are making more power than stock. Your mods are very mild so I'd say you are doing o.k., but there should be a bit more in there somewhere.
Those headers should bump it up another 10-15 at the wheels, maybe more.
You may want to remove or gut your main cat (or highflow if tested) when you do the headers unless you've done that already.

Re: 1st time at the dyno (jmrl98)
A very important question that needs to be asked is what type of dyno you were using? Was it a Dynojet or a Mustang Dyno? The Mustang Dyno people will argue until they are blue in the face that their dyno is more useful, etc. That's great, but the numbers they give are completely different. If you want to compare with other people you need to compare apples to apples.
Most people use a Dynojet, if for no other reason than they are more common. Thus if you had your car dyno'd on a Dynojet, you can compare numbers with most of the other people on the forum. If you used a Mustang dyno realize that your numbers are likely to be a lot lower than they would be on a dynojet.
Which dyno is better is a completely different argument, and frankly it doesn't matter. What matters is that you only make comparisons between people who used the same type of dyno. :cheers:

Re: 1st time at the dyno (Nathan Plemons)
It is a 4+3, and 230/330 are the stock numbers. The dyno was a mustang, and when I said "that's it?" to Greg (the guy running the dyno) he said I sounded like the Viper guys!! "Welcome to the world of the mustang dyno" is what he followed up with. :lol:

Nice meeting you out there this weekend John. It was sorta misleading with a big DynoJet sticker on the door to the dyno room, but they were running a Mustang. They must have recently changed.

Nathan,
Very interesting. I ahve read the Mustang dyno understates power while the Dynojet dyno overstates. Yet, the dyno shop I have gone to says just the opposite.

Nice meeting you also Jeff :cheers: Too bad you couldn't get that stroker on there - you did a great job on that engine! :seeya
Thanks for the tip, Nathan. Keeping it on a mustang dyno is the best way to see what gains from any mods. :seeya
