Tuning a blower motor

Ok I have asked and asked on the Computer board with no responses what so ever.

I have LT1 Edit, a laptop, and cables and somewhat of a 'base' tune that was a hack job of Ed Wright's program and some help from my friends when the old motor was together.

After the past couple years trying to get this thing together I want someone that knows what they are doing and will get thing thing to run right. I'm willing to trailer the car to where it needs to go. I have a couple options sitting in the background but both are over 900 miles away.

So does anyone know of (by experiance) good tuners in the Midwest that have experiance with blower LT1 cars.....if they have knowledge of solid roller motors all the better.

Ideas, thoughts, experiances, and reccomendations welcome.

www.kennedysdynotune.com which is my "home away from home" if my wife is to be believed. If you come, I will take you out for a beer.

Whats going on with your car, whats it doing? I had loads of little problems, and blamed them on the program. Its a little to rich, but Im going to the Dyno on Monday to get what Brian@PCMFORLESS needs. Other than that my car runs real smooth in all rpm bands.


As for a tune i guess you could meat with Brian some place. He is on the road all the time and you might get lucky have him intown.

I would also highly recommend Bryan at PCMFORLESS.

He recently street tuned my car and it ran great..I did have him tune it on the conservative side till I get to the dyno.

He currently lives in PA so I just drove up there. I went back like 2 weeks later to have him fine tune my block learns at cruising speeds and fix a little problem I was having with the torque converter not locking up as easily as it should. The car Idles Beautifully and I am now getting 14 MPG in 50/50 mix (city and Highway driving) and 17.5 MPG on 90% highway and 10% city driving ( usually drive 80MPH on the highway). This is with a 3000 rpm stall and 50# injectors.

You can click on the sig to see what all I have done but other than the blower whine and the 3000 stall, you can hardly tell that anything was done to the car...His tuning ability is THAT GOOD! He must have spent only a TOTAL of 2 hours to get my car this good too.

I highly recommend him

Thanks,
Claude

Jim (INTMD8) at speed inc is the man when it comes to tuning. He personally had a blower lt1 and now has a turbo that he made himself. They are located right outside of chicago. I would stay away from a mail order tune like pcmforless with a car as built as yours

If you don't go to Speed Inc, there are a couple good ones in the Metro Detroit area. Detroit Speedworks and APE are both very good, many people in the Great Lakes board will swear by them.

Well as to whats going on with the car....and why its taken so long....do a search....to long to type out all of the motor problems.


As for how its acting right now. Well still rich as crap. Seems to rev a lot better the last time I started it but I still don't have the blower back on it nor is there any thing after the headers for exhaust yet. So I still have a week or so of work to do.

Before it never really ran that great.....especialy at lower rpms. Always seemed really lathargic and just seemed like it wanted to load up......maybe thats the nature of the beast....as this is my first blower car.

Just always seemed like the car should run better than what it did. Never really seemed to have that great of throttle response, never really seemed like it ran to smoothly....just a lot of little things.

Whole new motor this time around, built by Nick at Nu-Tek, and the blower is now fixed so hopefully ATI got it right and Scott was able to fix everything else with it. So mechaniclly I think she's in a lot better shape than before......now I just need to find someone that can do the same for the computer.



I have talked with Jim at Speed Inc. when they had their open house. I have not talked with anyone at Detriot Speed Works so I don't know but I have heard of them. rskrause....did that place do your car as well? Never heard of them before.

Thanks for all of the options I'll just have to start calling around and pick one I guess. Just want to make sure that the persons and shop involved have a good outstanding reputation, hate to see everything go away because of a bad tune.

Kennedy's is the shop owned by my friend Bob Kennedy. He has worked on cars for ~45years, racing and building race engines initially while doing general repairs to pay the bills. Now he does exclusively high end performance work. A lot of SC installs and fuel injection tuning, installation and tuning of aftermarket ECU's, etc.

I am over at the shop 3-4 nights per week and most weekends fiddling around with various things. My contribution is that I know a fair amount of theory, but much less in the practical realm. Bob likes to bounce ideas off me, and I think I contribute something. Bob has an extensive knowledge of motors, fuel injection systems, drag racing, etc.

I am an unpaid volunteer, but in return I get a break on parts, tuning, and stuff I can't do myself (which these days is a lot with my bad back and work schedule). Bud Link is the head mechanic and he does phenomenal work. If you saw how he fitted everything under the hood in my latest combo, you would see what I mean! The shop is well equipped, clean, and organized.

So, I am biased. But trying to be objective, here's what I would say about the shop. Superb quality work, high prices, but worth it if you can afford it. Bob is scrupulously honest, probably to a fault in that he won't sugarcoat or oversell things to butter someone up and make a sale. He also stands behind what he does and the parts he sells. Overall, a class act.

Bob has spent thousands of hours dynotuning blower and other exotic combos. He charges $125/h for fully instrumented dyno sessions. Assuming no mechanical problems, it doesn't take long to dial in WOT AF ratio and timing on a blower car. That's in respect to optimizing what you have. What often happens in a dyno session with a new combo is that some weakness is discovered. My point is not to mislead you and say that "it will take two hours max to optimize your tune" or something like that. But Bob is willing to work with a budget and does a lot of jobs on the basis of "get what you can done in a couple of hours". But he doesn't like to do things half-assed and prefers that cars leave the shop in perfect tune.

Anyway, I am really rambling. Just wanted to give you the straight story.

BTW: much of the content and some of the design of the web site (www.kennedysdynotune.com) is my work. I have just been starting a new section called "tech tips". Check it out. My car is also on the site, though the info needs some updating.
