I think there is either something wrong with your tune or your intake. I'd follow JRod's advice and switch back to the stock intake and re-dyno.

 

How do you quote someones post?

Thanks

 

Holy f'uck you're really going to sell it at auction That's gay as hell. Take off the damn mods, break the motor in, re-dyno. If it's making 330's then sell the damn thing.

Give the car a chance to be all it can be before you disrespect the best American track car made. Shi't take it to an auto-x or HPDE where you see what the car's made for, 15 rwhp won't mean s'hit out there.

Yes you make me mad :mad

 

 

Dude get a life

 

How do you really feel

Are we at page 3 yet

 

Hey you got that quoting thing down pat!

Well, except, you actually quoted the wrong poster

Have you sold it yet?

Actually my life's just fine... I'm really enjoying my self right now. Single, 22, living a minute walk from the beach, drive a Z06, and having a jetski that goes 65 mph!

 

Cobra, I didn't mean you. Sorry

It was directed to Lager

 

Now I'm confused? Oh well...still funny.

 

Ok, the hell with the quote's. I believe it was Cobra the got his pantie's in a bunch sayin "holy F--k" you're really going to sell it. Chill and let's keep it adult like.

 

So what are you going to do with the car now after all this ?

 

Howdy!

*This* is exactly why I don't get all jacked up about dyno numbers - there's just too many variables! Heck, you could put on some lighter wheels, turn the drum quicker and have higher numbers, or have a mis-cal'ed dyno, or not have the appropriate correction factor, etc., etc.

You said in a post above (previous page) you had 3 other Z06's? (You said: "This is the fourth Z I have had and do enjoy driving them. I was just expecting more") Did you ever dyno the other Z's?

How about taking it to the track? Check out what the gearing and weight will do in the 1/4 -v- a dyno number.

I mean dyno numbers are fun, and big HP can be fun if it's usable - I had a Supra that would have sucked the headlamps out of your Mustang, but the Z with it's linear power delivery, nice low end TQ, and really amazing track (as in road race) manners is _much_ more fun to drive. I don't get to brag about 700HP dyno numbers, but it's no loss in my book.

Whatever you decide, best of luck!

 

I would at least have gotten a second opinion. Different tuner and different dyno just to be sure.
But, I can't say I get the impression you are a Corvette owner, but just a automotive hobbiest. Nothing wrong with that, but some folks here are passionate about these cars and that is why you are getting a bit more flak then you really deserve.
Have the car rechecked by somebody else, provide us with the facts on the dyno (type, correction factor, air/fuel ratio tuned to) and get back to us. Even if you do end up selling the car maybe we can learn something from this.

 

Sorry to hear you are dissapointed with the results of your mods. Just after I crossed 5,000 miles on my Z, I took it to a Dyno Day. My bullet shows 340 rwhp and 340 rwt, right where I expected it. However, another Z owner was terribly dissapointed when his Z only weighed in with 320 rwhp and 315 rwt. Because his Z was same year and options as mine (although, different color), we compared notes to developing an understanding of the difference. His Z had nearly 15k more miles than mine. However, the big difference was gas. My Z only feeds on 93 octane, his was being feed with 89 octane. The dyno operator said, "yep, I see it all the time, the lower the octane, the lower the rwhp."

Now, I doubt that your Z is being robbed of HP by using octane lower than 92 or 93. However, I waited until I had more than 5k miles on mine before hitting the dyno. Right now, I don't remember exactly why I waited until after the 5k mark. However, I believe I was doing so based on what I read in postings on this forum.

Based on my very limited experience, I suggest you put at least 5k miles on your Z before dyno-tuning to max out your rwhp. The time and effort it takes to do that won't significantly increase the depreciation on your Z. And, it may provide a different result that would have a positive affect on your opinion of the mods you made.

I can't resist: So how many hot babes in your hot tub each weekend, or just cruising the waves while others wait on the beach... ?

 

Dude, you need to be calling for 'Miss Xylene' for your next dyno run, it is 117 octane and you can get it at your big paint store in 5 gallon pails.

[It's a paint and thinner solvent.]

Mix it 30% Xylene -- 70% 93-octane for 100 octane fuel.

 

Lower octane is not necessarily going to cause lower RWHP. The use of lower octane could cause knock and the PCM's knock retard is what actually causes the loss in HP. Knock retard is easily seen on a dyno chart. It looks like a sudden drop in HP that continues throughout the RPM range.

If your car does not knock with 89 octane then it is not going to make more HP with 93 octane. My Z06 will knock at WOT in fourth around the torque peak if I run 89 octane.
