I forgot to mention, I'll be on a Dynapac for my pulls. I'm told it is more accurate, there are no spinning drums, this will be hooked up to the wheel hubs with the rims and tires removed.

 

looks amazing! when polishing do u have to polish all in the same direction too? is ur alterator polished also?

 

Looks promising. I'd have to agree though that without a before/after, it is kinda worthless because the particular dyno may read abnormally high or low. Hopefully this won't turn out like many other threads like this where people never give the info and just drop off the face of the earth, or give numbers without any baseline.

Regardless, I'm hoping for the best.

 

I'm trying to buy a stock plenum from another member. I sent him a PM but I haven't heard back. I will get a stock plenum and show the reusults of that too.

 

bump.

 

Yes, polish in the same direstion. No, my alterator is not polished. I bought some aluminum and I made a new pop charger bracket and I'm still working on an engine cover....it's only to cover wires so it's pretty small. Right now it sits up to high and makes the hood bow, more work will be done on it tomorrow.

 

242 HP / 224 Torque

I won't be able to post the graphs until tomorrow but, you will be surprised at what you see........

The air/fuel ratio was great, mid to low 13's up to about 4700 RPM's then to the high 12's from 5600 and works it's way down to about 12.4

My RPM's are a rock solid climb. There was another Z that dyno'ed right after I did, his graph was completly different. We matched a lot of our cars part for part the differences were, My lower plenum, Sun Hyper System, stock exhaust. His car had a Top Speed Exhaust and Strup headers, different Y pipe, but it was aftermarket and Pullies. He pulled 266...I forget his torque # but, I will ask him. Now I have the shop pricing out a header install.....

5th gear pull, 3.73 ratio, yes we realized later it was slightly off but the other Z like mine ran about the same with a ratio in the 4's as when they corrected it.

 

thanks for posting

 

Is your 5AT or 6MT. I'd expect a lil bit more if it's a 6MT. For 5AT, those are some great numbers you're puttin there

Again, thanks for the dyno specs

 

6mt

 

Thanks for clarifying, I thought that you'd get more if yours is an 6MT, do you have a baseline to compare to?

Also, you don't have any piggyback or fuel management system don't you?

 

Well, those numbers don't really tell us much. I'm more interested in how it changed the area under the curve, not peak numbers. Looking forward to seeing the sheets...

 

+1 I'd like to see the dyno chart of before and after.

 

I saw his engine yesterday...the polished pieces look great!!!

Murph, I'll buy beer if you want to get together next weekend to work on mine!

 

You should be able to do the header install your self Murphy I did mine myself, took 5 hours on Jackstands. Not so bad.

Good numbers, i would be curious to see what your car would dyno on a dynojet. Kinda tough to compare, plus no baseline with stock plenum i take it??

I talked to the owner of the shop a lot, he has a real strong interest in Z's so we are going to work out a meet date. If someone has a stock lower plenum, I'll put it on and dyno again to get the results. I tried to buy one from a member on here but he never got back to me.....$50 shipped. I was too busy today to get the sheets scanned but I will have them up soon along with a few update polishing pics and some engine item I made.

 

Feedback is welcome, this was my first time on a dyno. Hearders are the next thing I'm looking at doing.

 

If anyone knows how to rotate the graphs and post them on the thread as a pic, it would be appraicated.

 

Here your go.

 

Looking at your dyno and your A/F ratio, with your mods it looks like your car makes more power around 13.8 a/f from 3000rpm to 4000rpm then from 4000 to 5000 around 13.5 a/f and from 5000 to 6000 13.0 a/f then from 6000 to 7000 i would have it set at 12.5 a/f.

I think you would be very suprised with your car if you had it tuned.
