So, I thought I would sport some of my good numbers today.

282hp 269.9tq





ZZP Stage 3 tune // 2.9 pulley // 50#ers // Dual pass end plate // 0ttp Heat Exchanger // Opt B // Magnaflow 2.5" Exhaust // 0ttp Longtubes // GMPP Clutch // Fidanza Flywheel

 

That has to be a happy dyno. A zzp stage 3 canned tune does not put down power like that. I am also going to assume that the power is at the crank.

Unless ZZP made improvements to their tunes.

 

325hp to the crank it approximates. 297 tq

 

let me get on that dyno. a 2.9" making 270ftlbs

 

the car was dyno'd in 3rd, and did pretty well, good job Sean. Wish we couldve gotten more of our members on the dyno

 

It dont matter if the car was dyno in 3rd numbers are still way to high.

 

Maybe it's a good engine? Nice job

not on meth or e85?

 

Also i just noticed the car was only taken too 6200 rpms they is no way it put down that kinda numbers and not even going to redline

 

No meth or e he said that on the redline forums.

 

I don't care. I realize the numbers are lofty. I have heard reasons why my numbers are higher than what they should be and everyone has something different to say. 3rd gear is a great gear for fi cars, it isn't a 1:1 ratio of gears...

I have read about it and come to the understanding from various sources that most of those are 'wives tales'. Honestly, I don't care what the dyno says, I care about track results.

I have ran a 9.21 1/8 with crap 60ft (2.28s) so I imagine if I hook on a cool day I could be in the 8.9X 1/8th. We will see on Saturday when I hit the track. I will be @ Texas Motorplex which is a 1/4 mile track.

We shall see.

 

Good numbers but would gave to agree seems high. I'm on a zzp stage 3 canned tune and out down 234/210 just last month

 

9.2 1/8 with that powerband is gonna be sitting around a high 13

 

Here is how i look at it, do u see anyone else in the dyno section on a 2.9 pulley without e or meth making 280hp? No u dont 280+ is around the hp meth and e makes on an lsj with bolt ons.

 

Like I said I don't care. I only care about track results. The reason I hopped on the dyno was to shut up haters and those pseudo numbers worked for non educated people.

It proves a point that dynos aren't for anything other than tuning. If you go from dyno to dyno, your hp range will change dramatically.

 

I am hoping to break 14 in the 1/4 but my goal is to get my 60ft down and the rest of the numbers will fall in line. I believe a 1.9x ft is possible with street tires. last track I was at is known for terrible track prep. That is where I ran my 2.28 60ft. I was spinning through 60ft.

Texas Motorplex is known for its big races. It holds a lot of the nhra records so they know what they are doing. If I am going to break my own record it is there.

Of course, the this is all before e85 conversion so baselines before that and built head/cam later will give some definition to said upgrades.

 

On a 2.9 with cooling mods, I have seen 240-260hp. 234 is low. I it must have been a Mustang dyno. That being said, I have a few more mods then just 2.9 and cooling mods. It all goes back to what I said: dynos are garbage for anything other than tuning. There is no standard. You may as well be tv shopping by contrast ratio or computer shopping by cpu frequency (ghz).

Track ET is a lot more accurate representation of your numbers.

 

See what you trap at the track and that will give you a good idea. Like you said dyno's vary from one to the next. I once put down 328whp on a dyno dynamics, then proceeded to trap 119mph on slicks.

 

I don't think you can get a 1.9 in the 60' on street tires. I have seen some do 2.0 with a really expensive street tire. I usually net a 2.2 60' on horrible cheap street tires. I ran a 9.2 @ 80 MPH in the 1/8th and 14.0 in the 1/4 @ 102 MPH.

What was your MPH in the 1/8?

I ran that time with GMS2, Opt B, Dual Pass, H/E, Phenolic spacer, I,H, DP, & E. I would say that IF I had put my car on the dyno I would have been around 245 WHP.

You have a smaller pulley than me. If you can drive good. You should see high 13s. Check out the drag racing thread on how to launch the car better.

I wasn't trying to be a douche about your numbers but the dynometer is like bench racing. People think with higher numbers they are faster.

 

people on 2.8 and 60s usually only get around 260 whp...

othe rbolt ons included ofcourse

 

Though it may sound like it over the Internet, I didn't take it that way. I am just trying to prove a point.

on the 9.21 1/8 I was 78.81mph. I started the pass at 140* iat2s. There is a lot going on there wrong. I was spinning till 2nd where I throttled the car back to stop spin then layed back in it. It was a hot summer day (looking for icebox if anyone has one) so temps iats were high. Track prep was garbage. It was bad enough I was out running brand new camaros and mustangs.. Well, all except the street radial and the first cars. The the stock cars were all running high 9s. A lot of that is driver though.

I have Bridgestone potenzas and they hook a hell of a lot better than my old kuhmos.

 

good job!!!

I want to jump on this dyno

 

I don't like to do back to back passes with my car. You could have your coolant system routed incorrectly or a dead IC pump. I got the Phenolic spacer and I think that anyone with the LSJ should put this on the must have list.

My tuner even told me he had never seen an SC with the temps I had. I used to have a TVS with a 2.8 pulley on it when he said that.

I am now going turbo. I think I am going to make a how to video on how to launch the car. Potenza's are really good tires. Even with bad track prep you should still net 2.2 or 2.1 60's. Also, stay in the dull lines at the track. That is a completely different topic though.

 

i made 280whp exactly on my 2.9 with E so... just sayin lol.

 

i need to get on that dyno!

 

Numbers sound optimistic for mods and 9.2 @ 78 1/8. My old GTP made 212whp and ran 8.77 @ 79 and 13.71 @ 99.1 w/ 1.98 60'. My current Volvo 850 that has never been dyno'd but should be around 300/390 3330 lbs w/o driver ran 9.114 @ 82.7 and 13.80 @ 108.1 w/ 2.37 60'.
