And boom goes the dynamite. 2nd motor down

[GNBRETT]

its not a TR if it hasnt gone KABOOM at least once a year.....

I wonder if this problem could have been avoided if you were running an XFI? Would it have made the fuel correction to overcome the over rev?

If the alky pump was shut off as well as the fuel pump being under control of the XFI. But doesn't the XFI kill the spark as a limiter? I could be wrong.

To the original poster. I know you feel bad but don't lose sleep or make yourself sick over a car. Thats all it is at the end of the day...a car. Fix it and get what you need for protection to enjoy it again. :redface:

With all due respect you dont need to upgrade the fuel pump, you need to get the car tuned correctly.

The tune was fine. He has run the car 1/4 mile multiple times since it was built and has not skipped a beat.
The fuel cut off in the chip should be 6375, If he was going around 150 MPH in 3rd gear he was definetly at/near that rpm.

The XFI would not save it. the boost is well above 20#,even if it replaced the fuel the octane is not there once the alky shuts off.

Fred's car is a chip car. When the meth knob is turned down you must add fuel with the chip to compensate for the difference in meth you remove.

An audible knock gauge is in my near future R they loud enough to hear?

With all due respect the car was tuned to 135mph on a chassis dyno and had a very conservative a/f. We have made nearly 150whp more in a Buick with a single pump and 2 nozzle at 25gph. Granted we used 116 octane fuel but he had more than enough pump and a conservative tune. Unfortunately the engine was likely operated at or over 6375rpm. Which is the highest the rev limit can be raised without removing it completely. The rev limited on a stock ECM car is not debatable. Either raise it to 6375 or remove it. It's likely this engine was under power for nearly 20 sec to achieve speeds of 150+mph. It's not too easy to tune for those conditions and time under power anywhere safely.

You may very well had no KR on that blast. The best thing to do is avoid running out of the parameters the engine was tuned for. The engine isn't making effective power over 5800rpm in that combo. No need to be anywhere near that rpm.

I brought Alky from 5 to 4.5 and fuel up from 137 where u had it to to 138 Done this a few other times on nights in the low 70s high 60s without issues. So my problem must of been the limited cutting fuel. Like I said b4 at least 150 he was going 130 ish Abd I passed him like a slow car on thruway

So what's my move for safety? Tach with shiftlight

 

[jasjamz]

Knock alerts are loud, but the proper placement is key. You can't grow to ignore it like some do either. Scanmaster in my face is all the alert I need. When you hit overdrive on the highway... game over!. If you haven't won by then, they're faster.:tongue:

 

[TurboRegal84]

If you haven't won by then, they're faster.:tongue:

Wow...that is quote worthy! It is easy to play Monday morning quarter back with a situation like this. However roll racing with a Turbo Regal is always tough. At highway speeds there is alot of load on the cars which can make issues arise fast. Plus you also have to factor in aerodynamics. Our cars are not top-end cars. They have tons of torque and are fantastic at smoking the competition off the line....get them off the line and enjoy the sight of them in your rear view.

no audible or visual warning device will help if you break the input shaft on the transmission. You won't be able to lift fast enough.

I can't wait for that!! Honda boys around here r talking so much shyt Bc his civic went 10.9 And sense my cars down we have noone that can best him. He's talking $2-300 too. But it looks like it'll have to wait till next yr

Tell him to bring that Honda west a couple of hours, I'll take his money. I don't do alot of street racing, but, I'm curious where you found a road, long enough, straight enough to hit 150mph?? FWIW, if you haven't beat him by 130... might be time to concede, live to fight another day. Good luck with the re-build. Phil.

Idk what I was thinking I shoulda not of toyed with him n just best him by a mile from the 40 roll. He's a 12.0 car at best and so that is y I didn't go wot till 80

Ive had a planet break at WOT about 11 years ago and a pump fail at WOT. Both times the engine probably hit 6500

 

[bison]

Our cars are not top-end cars.

What qualifies a car as a "top end" car? Ive raced street bikes and super cars with my lowly black GN and bitch slapped them from highway cruise up to about 145mph. I just dont see the need to go much faster than that.

Sorry to hear about the motor...I know the feeling all too well.

Sorry to hear about your motor. As a wise man once said, "Sh!t happens!" When I mess around with mine on the street I try very hard to be careful and watch for knock and lift if I see any and so far (knock on wood, pun intended) this has worked for me. One thing to consider and I am a firm believer in this is there is no real replacement for octane!!! Alcohol is a great addition, but by no means do I think it is a replacement. E85 has shown some impressive results on various cars, but I still feel safer with running race gas. If you're gonna play you gotta be willing to pay!

 

[Phoneguy]

The wise man should have said " Sh!t happens, and happens, and happens " , at least in my case. With what I have spent on this car it should run bottom 9's!

sorry to hear about the hurt motor.just have to fix it and learn from the situation. things go buy fast and there can be alot of distractions in a street race.sounds like you held 3rd for a really long time.can't take the paper with you if you enjoy the car put her back together.doesn't sound like there was anything wrong with the tune or the fuel.but either way putting enough scanning devices in the car to make you comfortable is the way to go.i like the wideband and fp gauges directly in front of me,with a visable tach.

 

[turbofabricator]

Get the Bob Bailey rev limiter/two-step. Best couple hundred bux you can spend. Solves your issues with out removing the rev limit in the chip, AND......Lets you launch the car at the track on a two step. WIN-WIN.


There, Bob, You can send me my $8,000 endorsement fee we talked about.:biggrin:
