Thank you!

BTW did you ever get that CAI worked out for the Vortech? I was going to fabricate one in the near future.

 

What about johns car? It had the smaller pulley test pipes and cams. Wasnt he at about 10psi?

 

John is making 435rwhp w/ the 2.87 pulley. He reached 505rwhp when using the intercooler chiller. Our setups are similar. He has the JWT cams, test pipes, etc. The biggest difference is the fuel system. I have larger injectors, fuel pump and a new fuel delivery system. He is still running the Vortech aux fuel pump with stock injectors. I don't know how much psi he is getting.

 

Aw got ya!

 

Yep I care less about your 475 to the wheels then your air fuel. I care more about how long that 475 to the wheels will last and that is where the tune is more important than the peak numbers. We all know that poor tuning is what kills most motors. I would also like to know what kind of ignition retard numbers you are running. Did he do a step retard or a per psi retard?

 

If the car is a little running rich right now, I wouldn't worry too much about longevity, but thanks for your concern. booger asked about the timing as well so I will find out.

 

rich is definately better than lean, we all know that...but the original dyno sheet that u posted...looks like thge A/F struggle sin the high 12/13ish zone until 4000rpm...maybe richen it up a little earlier...

and don't get so defensive with the criticism here...
i have great assurance that when i ask a question or post a result on this forum that i will get lots of feedback...teaching me more about what other people are doing and what the "norm" is...this isn't an attack, some may come across that way, but you should welcome the critisism of others who have more experience

that's great that you are making 475 with a supercharger... hopefully the tune will be dialed in a bit better, you'll probably make more power and have a cleaner/steadier feel to the pull of the car

 

 

Great numbers....got 374 with stock pulley...going with the smaller one and new plenum to see what I get. Just want to be over 4 with the Vortech and I'll be happy. Nice to meet you on Sat Andy (McDuck).

 

374 is pretty good with the stock pulley. I only made like 360 out of the box. You can definitely hit 400+ with the 2.87 pulley and possibly with the 3.12 as well.

 

No, that project just fell apart. The fabricator got innundated with regular business and has not time to R&D the part construction for me. Still would like to find a solution for this, but I have nothing in the works right now.

 

Did John rebuild his bottom end as well? I would think so with that 505rwhp number, but don't want to make a false assumption.

 

Nope. John has stock internals. Lucky guy I guess. I bent 5 rods.

 

Hmm... makes me think I might want to look at an intercooler chiller. Don't want to get crazy, but it may be enough to get me safely to 450rwhp.

 

No he didn't, his numbers are on a stock block. His motor is being torn down now for build up.

 

Yeah, the chiller is great. It cools the intake temps considerably which leads to better combustion and more horsepower. It is probably safer than other options to push the horsepower limit because you will only increase horsepower after you spray the intercooler.

John has a really nice setup with an automatic bottle opener, purge system, etc. I definitely plan on installing one in the not so near future.

 

just remember with the n-ter-cooler you are lowering the charge temps, effectively leaning out the a/f curve. make sure you fatten the fuel curve a little to compensate for when you spray the cold stuff on the intercooler.

 

So, with the chiller spray, he normally is running a somewhat conservative a/f with less timing pulled? Then, when he wants more power hits the spray?

Just wondering, since you cannot adjust the SS box on the fly, how he set his timing and a/f ratios to take the best advantage of the intercooler sprayer yet not sacrifice his non-spray power much.

 

I can't say for sure, but I believe his A/F is somewhat rich. Somewhere in between 10-11. So there is no worries. As far as the timing goes. I don't think it is any different than if he didn't have the chiller. I will try to find out for you Andy.

 

If he gets extra boost from the chiller , its possible to have both tunes on the same map . As the boost curve would be in a different area of the map . Dont know ????
