Yeah the raw numbers don't lie. If the car has done a 1.41 short time in the past and yet was still able to run a 10.65 on only a 1.55, then logic would dictate that there should be (key words there are 'should be') at least a solid low 10.4x and another 130+mph in the car's future.
It doesn't always work out of course and adding some power can often aggravate traction issues even further but all it takes is that one clean pass to bring it all together.

maybe i should take joes advice too

7. Dyno numbers if you have them: no
8. As much info you may want to add about the run, launch techniques, tire air pressure & etc - Please note that the speed on the timeslip is in km/h. Launch at 4800 RPM
9. Typed in the post (as some time slips get deleted & etc after being posted)
___ Name of the Track: Kunmadaras Airport/Hungary
___ Date of the pass & weather conditions-30/04/12 DA 2000feet

Got a speed record as well, 127,55 mph. Decent in a DA of 2000.



And on the way home (!!!) this:



So bye-bye drag racing for weeks or months, because it takes time to get things together in Europe. Was it worth? You betcha.

Joe_G

That's an unusual break...normally the 05's do this!



Sorry to hear it.

sebaj

Joe, thanks, I already had a built C5 diff in it, don't know what went wrong, the output shaft of the tranny is broken in two, looks like it pushed the diff internals back, but we could be wrong. Will know better tomorrow. Looking for a tranny now.

Joe_G

Having just replaced a tranny for the third time (twice my fault once not my fault) I feel your pain.

I covet those with a 6060 trans...I might have to just buy one new if this happens again and have my ring gear enlarged. You might consider that.

sebaj

Don't wanna make it off-topic, just one more pic to share:

Joe_G

I'll see that pinion and raise you one pinion and 1/4 of a diff case!



We 05 owners have a lot in common.

LS1LT1

lol

Why are your reaction times 3.5 to 6.5 seconds? Turbos building boost? Just curious.

sebaj

This was a test and tune day, and as this track is the only one with track prep (more or less) we experimented with several different launch RPMs, andI wanted to get ithe RPM really on the point for recording the results, since there was no reason to cut better reaction times.

dicky

i dont seem to have a problem with the temps getting to high but im not in down town LA at rush hour either. my temps seem to be ok but i dont see any kinda of performance gains from this EWP at the track. It will cool off quicker since i dont have to have my car running. If I was to do it again I would just leave the stock one on.

theofel

I had an EWP installed on my car for about one month. I also did not see any gains at the track and saw no real benefits as a daily driver. Had it removed and sold it on this Forum. Used the $$$ for better things.

Joe_G

Based on my review of GMHTP, if my memory serves it was a 8 rwhp gain. But for bracket racing or even chasing a record, the ability to cool the car in the lanes can be a real time saver and factor in consistency, when combined with the Caspers fan module that allows you turn the fan on when the car is off.

p.s. I have a Caspers fan module brand new in box I'll sell for half price if anyone wants it. I keep forgetting to list it for sale.

If you are going for a record in any category, it is a worthwhile mod in my opinion.

Except for automatic trans guys, proper (read loose) converter selection is nearly the entire ball game.

It would be the one of the last mods I put on. As evidenced by the fact I don't have one! lol

JUIC3D

Joe do you think it's worthwhile to run the fan in the staging lanes with HPT? I've never done that and didn't realize HPT had that potential until recently.

Joe_G

I'm not sure the capability works, it didn't used to on the c6's, maybe it does now but I kind of doubt it as the fan is a fancy piece of electronics in our car.

It's important for bracket guys as consistency is their ball game and they race in the summer. When you are chasing records the weather is usually cool so it's less important. Plus for tuned guys, our cars normally stay at 192 to 200 when running which is fine as we have our fan adjusted.

BTW I wouldn't leave my fan on if I was you with that little battery. My buddy with a z06 had the casper fan control and it would kill his battery in the lanes and we had to push start him a couple of times. That ended that product's usefulness for him.

JUIC3D

It works. I've done it a few times just playing around with the scanner tool. You can change the speed as a percentage of maximum.

The battery might be a limiting factor but I'll play around with it and see. I've had the car sitting for over a week before and it fired right up with no issues at all. I've sat in the car with the radio playing and the interior lights on for 30 minutes at a time while detailing the interior and the battery doesn't skip a beat.

There's only one way to find out.

8850

I run my fan via HPT in the staging lanes to keep my coolant temps consistent. However, your IAT won't come down by just cooling the engine coolant temp. Best to keep the hood open as long as you can to keep that IAT down. With the engine idling the IAT will drop considerably more with hood open vs. closed.

dennis50nj

the ewp works great in stop and go traffic because it circulates the water faster at idle and low rpm, but at wide open throttle it circulates slower causing water temps to rise quickly and higher then normal during the run even the burnout, but will bring the temp down at idle on the return road

C7/Z06 Man

Unless its pretty much a "drag only" car I would stay away from electric water pumps (EWP). Trust me, they may look real neat/high tech and be OK for a period of time but motors/fuses may blow when you need them the most and may not be paying attention.
