I use Chad for all my engines. He just built me a motor for my 86. 109 block, Cat stroker crank, K1 rods, Diamond Pistons, Total Seal rings, RJC block girdle, ARP studs, etc. He does have the proper torque plates for our engines. He has built about a dozen LT1's for me, great guy to deal...

By "speedway" gas, are you talking about gas from the cheap-o gas stations called "speedway", or race fuel?

check the coolant temp sensor. If it is sending the wrong info to the ECM, it will mess with the fuel tables, which in turn will make the car run rich. The o2 sensor sees this, tries to compensate, but it can't compensate enough, so it sets a code for the o2 sensor. This would not explain the...

When I worked at Mack Trucks, we found that dawn dishwashing detergent worked best. It really broke down the oil. Then fresh water flush. I made up caps with an air fitting in them to hook shop air up to to help dry them out. Turbo failure was common on the Macks, and would always fill the...

Funny you put it that way, my wife is a Veterinarian, and the big pet food deal kept her busy to say to least. Thanks for your input on the newsletter, I just rcvd it today via email and figured if I posted it, you would comment on it. Dave

Here's some interesting reading from Blackstone. It's their latest newsletter. Not sure how much of it is accurate, but most of it made sense to me... newsletter

SteveX - That is not how our cars work. Go out and unplug the oil pressure switch and I bet your car starts/runs fine. The oil pressure switch is just there as a backup to the relay. The coil side of the relay is supplied power from the ECM. The other side of the coil is grounded...

I agree 100%!! My shop has installed many of their harnesses, and will continue to do so. I haven't seen any others built as well. We can build them in-house, but it is not cost effective when Racetronix offers them at the prices they do. Like I said in the original post, I just needed to...

Just got off the phone with Jack from Racetronix (he called me) and everythings cool. Thank Dave DynoTune Performance, Inc

I agree 100% Cme2fly, I would be willing to purchase another from them if need be. I own a performance shop and I know that parts fail due to no one's doing (I wish some of my customers would realize this as well). I also try and work with a customer that had a part purchased through me that...

I tried to keep this private, but I haven't gotten a response via email, and Racetronix does not accept Private Messages thru this board. I have a problem with a fuel pump purchased directly through Racetronix. I purchased the pump and hotwire kit some time ago, but due to rebuilding the...

The high rpm on startup is like that to help everything get up to temp, and to keep it running when it's cold (sorta like a choke on a carb). Open loop and closed loop are different, in open loop, the ECM doesn't care what the O2 sensor is saying, it's running off of a predetermined fueling...

Actually, it's not coming in and out of PE... The O2 sensor toggles (swings back and forth) during normal driving, this is called "closed loop". This is how the ECM self corrects fueling based on what the O2 sensor sees. The O2 will tell the ECM that is rich, the ECM backs off fuel, then...

I guess he took them down, don't see any either. If anyone wants to send them to me, I'll host for future pervs :) shop@dynotuneperformance.com

If they are wet, your getting fuel from the injectors, I'd be looking at the ignition system a little harder... Do these two cyl's share a coil (My Buick is at the shop right now, and I can't remember the cyl. pairing on the coils)

If you don't have a noid light, check this - With the injector plugged in, key on, engine off you should have power on both wires (power to the injector from fuse on one side, and power through the injector on the other side) The PCM fires the injector by grounding one side of the injector...

Just ordered a front left filler from my local chevy dealership this morning - part number 25521433 (but has been changed to a new number). It was around $67 my cost (shop account). They said I should see it tomorrow morning.

That makes sense Rich, why add a lot of "unknown" just to get realitvely small amount of what you want when you can add a little "unknown" to get the same amount of what you want.
