send me a pic of your car so I can attach it as well....

Thanks, man. It needs a wash. Badly.

Thanks, Rock. I was very impressed with the PS2s. My car did have the air-injection relay recall (the dreaded flash).

By the way, I was tempted to try the ECU reset trick and see how it might affect the car, but after so many passes, I had a hard time believing that the car had not already adapted to my driving "style", e.g., foot to the floor for 13 seconds.

Very nice. Your trap speed indicates that you're making about 540 HP in near-idealic conditions. Do you have dyno results for your car? Can you data log? It would be interesting to see what your timing is doing during a run, and compare it to others.

Ranger was very happy for me. In fact, I made sure to show him my slips in case anyone tried to call BS.

To watch him prep his friend's car and analyze data was something else. I had made 10 passes before he made his first. Between that time, he changed the clutch fluid, made all sorts of tire adjustments, set up his HD video camera and hooked up tiny microphones to the rear of the car just above the tailpipes. He uses the harmonic data to analyze shift speeds and other factors that 99.9% of the people out there don't even think of looking at. I envy his dedication.

And he is one of the nicest, most helpful guys you will meet. No ego at all. Just proven skill and work ethics. And probably lots of clutches.

I posted on Vetteforum last night to congratulate DrRon for his 11.22 pass on a bone stock Z06. Amazing.

enzom

Thanks Grumpy. I asked if there was a dyno nearby because I was wondering what she was putting down, but nobody knew of one nearby.

I never got into racing seriously enough to consider using a datalogger, but if anyone wants to experiment with my car at the next track rental, I'm more than happy to oblige.

As I said in my first post, the car was getting quicker and faster with successive runs, contrary to the heatsoak concerns that I had. I am fairly sure based on what I have read on this board that if I was running a K1, heatsoak would become a problem by the third successive run.

Enzom - thanks for nothing!!!!!

You have just demoralized every 55K owner on the planet - I want to take my CLS55 to the dealer and tell them to fix it or they can have it back!

And now I am beginning to believe Housclass's 11.9? pass which I and several others held with some circumspection .

But you have definitively proved that there is a LARGE variation between 55K motors

Absolutely STELLAR results - pat yourself on your back for snagging a friggin awesome car and for some awesome driving - that 1.66sec 60ft on streets is the best I have ever seen anywhere. Having a stong motor is one thing - but you did us all proud getting launches like that - I sit in awe!!!

305-E55

Congrats, those are some very good and consistent times.Sounds like you got the launch down to a science.

housclass

it was actually 11.84, 11.87 and 11.91.

i made a post at the beginning of the week that i believed that a stock 55 would run 11.9x's - 12.0x's all day long...i never had a doubt!!!

great job to enzom on some awesome times...killer 60's times man!!!!

i don't think he has proven that there is a large variation between 55k motors...i think he has proven there is a large variation between track conditions. you put most stock e55's on a few select tracks around the country and they'll all be running 12.0 or better.

Mike,

I sent you an e-mail regarding club day tomorrow at Speedworld.

enzom

Actually, it was so simple that it seems counterintuitive. Just a matter of squashing the throttle as I let off the brake. Once I trusted the technique and gave up on pre-loading, it worked like a charm.

Chiromikey - I think you are probably correct. But keep in mind that a track rental lets you waste as many runs as you want in the pursuit of the right launch. When you go to the track on a regular day, I think you tend to try too hard. Also, I really do believe that the car gets marginally quicker on successive runs. You don't get to hotlap at any track I know of unless you are renting it.

Next time I go to Englishtown, I will try the very same launch technique and see what happens.

Siswati - I would hope instead that I have motivated people to participate in private track rentals on a well-prep'd track. They are really a blast. My results should show that Housclass' times are legit. John still has, I believe, the quickest 1/4 slip for a bone stock car. Gives us all something to shoot for next season.

chiromikey

it's amazing how simple these cars really are to launch. it didn't take me more than one launch to know my theory was correct about preloading. we all want to revert back to our old-school drag racer days and preload the converter but these cars do much better off idle...just mash and go. i know it seems counterintuative to trust a car with over 500lb/ft of torque to hook on street tires but they do. like you said, once you trust the technique there's nothing more to think about. on anything except the most poorly prepped tracks, these things should still be able to stick 1.8 60ft times on decent street tires.

siswati

Yeah but there is a HUGE difference between 1.8 and 1.66 - thats an amazing 60ft time - my best to date is 1.769 and that 60ft time on dragslips is still one of the fastest on street tires

I am in awe of a 1.66 sec 60ft time on stock tires

chiromikey

1.7's can be had all day long on a decent track. head over to atco and you might post a 1.6 as well.

btw, I'm not trying to take anything away from enzoms times, they are awesome.

stevebez

No offence - on the contrary congrats on your fabulous times - but I would say allot of the result is due to the track ...

Obviously the car is no melon and is making huge power ... in ideal conditions ...

What confuses the cr*p out of me is the hot lapping ... whats going on here ?

Is it only modded E's that have the S/C shutdown issue or is it stock units too ... Personally I think its incorrectly bled intercooler systems that are causing most of the problems ... and of course faulty pumps.

ItalianStallion

My father's stock SL55 has the same supercharger issues you modded guys have. I've tried 0-130 runs and at around 110 the s/c shuts off. My friend had the same prob with his E55 but he used some type of liquid mixture in the intercooler and hasn't had a problem since. Now he is fully modded and still no problems.

Awesome run, you've cemented the 55k motor as a truly legendary engine.

enzom

Same question I have. I was surprised.

rflow306

It seems that when the ic pump is working correctly the system is more than adequate for a stock car. Several guys on this board like Fikse, Wayne and Siswati have shown this to be true.

SleeperX

Lorenzo,
Congrats!! You have 1 fast car... Very well done.....

chiromikey

true. i've seen several cars hotlap and show no significant signs of slowing down.

juicee63

AMAZING a 1.661 on street tires.

KrisKeeney

Enzom: confirm for me: "preloading" would mean revving to x,000 rpm, with foot on brake standing still preparing to launch, correct?

thnx

blackbenzz

Correct

thnx bro
