After a year and a half of my running down problems here in the northwest designing (rocket booster) muffler tips, and a check valve vented PCV system my forged 346 with high flow cats and wraped x-pipe made 545/525/35mpg@70/7lb with the final tune of Andy at A&A.

 

35mpg....:BS:

 

not bad...those numbers are close to mine when I was stock

 

I concur...That sounds kind of farfetched...Maybe 25-28mpg but no way 35mpg... Unless you planted a Honduh engine in there...

 

Tough crowd,

nice numbers btw

 

I couldn't even get that with my STS before I put the 402 in. Other than that. Nice numbers. Put it to the ground and get some track numbers now.

 

I think it's funny that some people go out of their way to insult someone else they don't even know and will probably never meet. BS or not, who cares...get a life!

Those appear to be good numbers btw.

 

For guys that hate the STS kit so much, they sure do spend a lot of time reading threads about them, then responding to them with stupid comments or emoticons.

 

That sounds awesome! I'm curious. Why did you just go w/ 7#'s vice either a higher setting or a two stage setting? W/ Forged Internals wouldn't you want to get the most out of your engine?

 

Maybe he was driving down hill a lot on that tank of gas

I've noticed a lot of haters as well...what's the deal with that? Those numbers look good to me.

Also, how did you get an X-pipe in with the STS???...is it a Vette?

 

Do you have a larger cam or is it stock?

 

I hope that you're not talking about me because in no way was I insulting the STS kit... My good friend had one on his car and I actually liked them a lot... I was just reluctant to believe that you can get 8-10mpg more than any other F-body, STS or not... It was meant in fun and games anyway so if it was taken the wrong way by the thread starter then I'm sorry... BUT if anyone says anything sarcastic in a "STS THREAD" then it must mean that they're bagging on STS... Come on, if I'm not allowed to have a sense of humor regardless of what kit it is then why is this country supposedly allowed to conduct free speech... If I was really bagging on STS then okay... I wasn't so please don't be so hurt... No one said anything about his numbers... Sheesh


To the poster, good numbers and I apologize for the comments... Who cares what people say on the internet...If you're happy with it and you do get those numbers, mpg and hp/tq, then awesome... I just don't like how some people are overly defensive when they think that someone is talking crap about THEIR sts kit... You would think that they developed it themself...

 

I think he was refering to the non-turbo guys (from the TX forum, cough cough), not you.

 

This cars gas mileage has always 'read' good and I'm using the onboard computers averages. I would really have to check it manually to be sure. But: 32@65mph before, 35@70mph after.
Also, he had to reduce the injector sizing because of a richness issue so that may be throwing it off, but, definitly 30+.
I know with simple $1000 fuel system mods the cars good for 650whp but I've never driven anything close to as fast as this thing finally is.
Cam stock on purpose, so I could maintain the good stock characteristics for trips like the one to Andy's shop.
The car has 42lb injectors so 7lb really did the trick.
PS: If I cared what some people said I would have blown my head off along time ago, and don't give the physco's an excuse is my modo and the Karate does the rest-

 

Damn those physco's!

Good numbers, btw...

Jim

 

nice results! i went thru a lot of **** too before i got my STS all together and running good, but it was well worth it in the end... i bet that thing's a lot of fun! m6/a4?

 

I'm sorry my car is a 02 Z06! with pilot sport cups, T1's, and 04 shocks. Like the curves Tooo!

 

nice results man, i would push for more PSI if i were you. if i went to 7.5#'s, i would be near your power...... i would turn it up if i were you

good numbers

 

Hell yea... I ran 9-10lbs on stock motor with LQ9 heads (drop the compression a touch) all day.... it was when I went to 12lbs that didnt work out for those Hypercrap pistons. If I had a forged setup I would be running 12lbs all day... racing with 15-18 if I could get it.

My setup now is completely different of course...
