I asked about the dyne comparisons because of my experience with way different numbers between the DD and the DJ. Before my car was put on a second dyne...I thought if there was a difference...it would be minor. But to my surprise it was not. It caused me to get DQ'ed because of my lack of info.

So you are saying that the person that got his car dynod at VRT and got 600 rwhp and when he took it somewhere else he got 350 rwhp is putting too much emphasis on different dyno numbers?

If I had known that my car would have dynod at 558 rwhp @ 14 psi (instead of the 501 on the DD)....I would have entered in a different bracket and I would not have been DQ'ed. Damn...I could have told the judges that DQ'ed me that they should not put so much emphasis on dyno numbers

I have seen so many Dyno charts on here with cars with the same turbo setup, same builds and way different numbers on different dyno's at the same PSI's. So if I want to learn about my car....of course I will ask questions.

 

^^^Your sig is a good example of that point. SO bottom line it for us...Are you happy with your car and the power you are getting??? (over 500 is a lot) Is it streetable? or must you keep the beast turned down for safety?
What psi do you run on daily basis?

 

Exactly. This is why you shouldnt put too much stock in the dyno numbers. For all you know the dynojet they put your car on read high for a dynojet. I've seen them vary greatly even within the same model of dyno.

When people say a dyno is nothing but a tuning tool they are exactly right. There's no set standard when it comes to what is accurate and what is not. The numbers given are ballpark at best.

As far as your VRT reference goes, that's completely unrelated to what I was saying. That sounds like just a case of dishonest sales tactics and fraudulent overcorrection applied to dyno numbers. Also, you never know what could have changed between the two dyno sessions...

 

What point


Yes I am happy with the power and yes it is streetable and yes its wise to turn the boost down when driven on the street. The car is hardly used for the sreet. I had it built for roadrace and speed events (drag racing Not included)

 

LMAO You should be telling that to people that only drive their cars on the street..not to someone like me that mostly drives on the track. You cannot just throw that statement out there for everyone. I have a GT car that was built for pro events (24 hour and 12 hour), they bracket you by weight, HP and purpose build. You have to round the numbers from different dyno's out. If I get 100hp on DD and 150hp on DJ and 180hp on DynoPak that gives me a rounded Idea of what I have. The club that I am a member of uses a DJ. It is your responsibility to know your HP before entering an event. The dyno is provided to all members....so I had no excuse for not knowing....but because Sharif told me I had 444 and 500 HP at a certain PSI I went with it. I have never seen a DD dyno....I have only worked with DJ dyno.

So maybe you need to post your statement to the officials that run the 24 hours of Daytona and 12 hours of Sebring, because the only thing that they put emphasis on is HP and Weight....and the only hp result they go by is their dyno.....

So you need to direct your statement to certain MY350Z members, not all.

 

Then perhaps you should have spent $60 to run down to the local dynojet and verify your numbers? If they benchmark their classes based on Dynojet numbers then perhaps you should have verified your car on THAT dynojet before entering a competition. I mean, a serious racing professional should take those kinds of precautions, right?

Most people I see claiming low "heartbreaker" numbers, interestingly enough, haven't even bothered to run on a dynojet before coming online to post numbers then "compare" then with other dynos. They'd rather post up calculations that usually inflate the "comparative" numbers even higher than they should actually be.

Anyway, this is drifting a bit off topic. Before it goes too far I'll say that I'll just leave it at that. Have a good one.

 

^^^^^Yeah thats right!!!! it's about meeeeeeeeeeeee!!!!!!

 

You know what...its not even worth my time to get into it with you. I see why "Old School" has a problem with you. You take a simple asked question and make a big deal out of it. The OP said that he was going to dyno his car on another Dyno so that I would understand the numbers.....that was good enough for me......but you had to turn it into this back and forth waste of time BS! So now...you "have a good one."

 

Yup...you have a great ride...it should be about you

 

You're the one that got defensive/mad. You have no point, but if you'd like to make one feel free to PM it to me.

But yeah, back to the topic at hand...

 

Yup. Props on the setup!

As far as dyno differences go, I think the car would make around the same power but a bit less tq on the average DJ, but there's only one way to find out.

 

This setup (as far as I recall) is running the most PSI for 93 octane pump gas. How safe / comfortable are you with running this amount of boost? UTEC is pretty good at detecting knock so i hope the car will be fine, but just wondering if anyone recalls a higher boost set up on pump gas w/ no meth etc...

 

^..and w/ the utec....pretty cool.

 

James and i had this conversation a few days ago. he thinks extended pulls in 5th or 6th gear(i.e highway pulls) will totally tax the single walbro, but normal everyday driving should be fine. we set the utec with 3 maps.

map 1: 13 or 15.5 psi 93octane
map 2: 18 psi with 93 octane( timing was pulled back just a hair for knock avoidance)
map 3: 18 psi with 93/100 octane mix

the key is the pump i figure. if someone*ahem* would come out the twin pump setup i would gladly buy one . but as for right now, i'm happy with the power levels and how the car was tuned. i might dump in some race fuel and see what's what, but for right now i'm just gonna enjoy having my car back.

 

You are correct. 18psi is a lot of boost from the 18g's on the VQ. UTEC is an awesome tuning tool when used properly. We've tuned up to 20 psi on the GReddy's (different car) with UTEC and 93 octane. It wasn't worthwhile though. We had to pull too much timing because of significant knock counts. For the amount of increased power, it wasn't worth the risk.

18psi on the 18g's is fine. I just don't trust the single walbro for extended power runs at those boost levels...so far, so good.

 

It wasnt so good for the 'busa i ran into last night. i guess he figured he could stay in whatever gear he was in and suck me up. WRONG! after i started to pull on him by a car length or so he cut in front of me at the light and just turned off. sore loser i guess. if i was on a bike( had a 02 gixxer 750) and a car was able to match me speed-wise, i would at least give him the thumbs up or something. btw, chris just compounded the g and that thing looks like a sheet of tinted glass! havent had a chance to try the 18psi map yet. funny thing is there hasnt really been a need to.

 

Thats awesome. You don't even need the 18psi map. WOW!!! I'm psyched!!!
I can't wait to finish up my project.

Thanks for the kick in the pants. Thats very inspiring!!

 

once you get it back on the road and tuned, there a few greater feelings than the feeling of the tt's spooling and those dumps! it's intoxicating, literally!!

 

Tony, congrats bud.... That is some awesome numbers... I'm jealous...

 

Wassup Wes!? I havent seen you since the Cleanpro show! I'll probably be rolling to the Z meet in ridley park on the 27th. give me a call if you want roll up there at the same time.
