If you are at the drag strip
How much faster can you go with street slicks like bridgestone RE55 or some thing along them lines

If the stock e55 dose 0 to 100kmh in 4.5 sec's how much faster can that time get with street slicks at the drag strip ?after a nice burn out

And if you had street slicks at the drag strip would you take off with the esp on or off ? after you warm the tires up by smoking the place

How much can they help the stock car

chiromikey

obviously, drag radials will be more consistent but imho, with practice you should be able to launch a stock car just as well on street tires as you can on drag radials. all the way up to stage 4ish i have been able to produce 1.71 60ft times on street tires and only 1.69 on drag radials. actually, i still can't do better than 5/100ths quicker on d/r's than street tires.

Not sure about the RE55's.. Sounds more like road racing tires. I do know BFG drag radials will net quicker ET's. General rule of thumb is every 1 tenth of a second off your 60 foot is 2 tenths in the 1/4. ESP off or better yet dyno mode and brake torque and let her rip! Not exactly sure about the 0-60.

Ohbev

but what advantage will dyno mod give me ?

chiromikey

none. there's really no reason to run in dyno mode as you can get a good enough burnout by just turning esp off.

Depend son how well you launch on street tires. If you are like some of these guys that can cut crazy 60' times on street tires then you probbaly wont gain much. After the first time I went to the track I knew street tires weren't for me!

chiromikey

i thought the same thing and couldn't wait to get my 16" ultralight ccw's with m/t drag radials. knowing the difference i've seen on past vehicles and others around here saying they improved 60ft times by 2-3 tenths, i was ready to run 10's. well i only average 1-2 hundredths improvement in 60ft times!

Can't argue with times like Chiros, but you gotta admit Mikey that it is a whole lot easier to launch on those MT's eh? (meaning any sticky tire) Streeters really require a near perfect launch.

I consider myself a pretty good racer, but I can't even get close to times like yours on street tires.

BTW Ohbev, I would ditch the Bridge thinking and go Toyo RA1's.

This is an 11 sec run with them on....AND INFLATED TO NEAR 40PSI. What a friggin trip. Trick to Toyos is to roast um. People will call you "grandstanding" but you gotta roast or your time is toast.

That's just an idea for a tire you can drive back for forth to work and then drag on.

Are you in the DC area? If so I have a pair of very lightly used 275/35/18 Toyo R888's I am selling

Unless your car needs slicks, i.e. you cannot hook on good street tires, they could actually slow you down because of the increased surface area and the sticky compound. They also increase your chance or breaking drive line parts too due to the no slip grip .

chiromikey

i'm not sure that drag radials are necessarily easier, but i do agree that they're MUCH more consistent. i've found that when track prep is marginal, the drag radials make a huge difference. with really good track prep, my launch is the same with both tires and my 60ft times are almost identical. i'd sure like to have a way to predict track prep like we can da!

In comparison to my throttle response of the six, after making a few passes in the E55 you should have no problem cutting great 60' foots with streets. The car I drove had Nitto 555's and yes roasting the heck out of them does the trick. I had rocks stuck to them when I came back to the pits. It's much easier to launch the E55 because of the slight delay in the throttle. You should use a feather technique on the pedal to acheive a good long burnout without letting the rpms get too high. The car's power is in the midrange, so getting a clean launch is more crucial than a hard launch. Now if you don't want to spin the dice every time up at the line, then yes get some M/T or Hoosiers consistent 60' times will be yours. These are true drag radials(slicks), the rest are softer compound versions of street tires.

chiromikey

slight delay??? i've read "war and peace" between the time i push the gas and the ecu decides it's okay to do what i ask. and the real problem is that the delay isn't consistent and therefor predictable. this kills any real chance at bracketing a car that's otherwise really easy and so much fun to flog down the 1/4mile.

cruzinquick

LOL. I was trying to be nice to the E55'vers

blackbenzz

My car has no delay, you think its the TB or is it just on all E55's?

chiromikey

lol!!!

my personal belief is that it's the ecu not sure what to do when both gas and brake pedals are being pressed at the same time.

Yacht Master

Your SC is allways on, that could be why no "slight delay".

Hammer Down

Andy said the same thing,it confuses the ecu when you power brake. The only difference that I found is that when I would power brake I would trap almost 118 and when I went off idle I would run 116.5-116.8. Maybe the few extra rpm's helped my trap speed.

blackbenzz

Did you spin when you powerbraked?

Hammer Down

I spun when I power braked and when I went off idle! remember I ran up at Sac!

blackbenzz

Usually if you spin you trap higher. I do believe that launching at a higher rpm gives you harder launches (at least with my car) but I've never launched an E55

Hammer Down

I ran 3 12.2's that day 2 power brakes and one off idle but spun on all 3. My best 60' was a 1.97.

chiromikey

i've been saying it for years and it's the reason i launch off idle in this car with so much success. launching by power braking always yields a slower 60ft but also take much of the lag time out of the ecu. if i bracket race, i'll give up 60ft times for reaction times and launch by power braking...crazy cars!

Ohbev

Hammer Down when your car was stock what mph were you getting?

So Is it better to take off with esp on or off??

Hammer Down

Was....It still is stock. Out of about 10 runs I average 116.5 to 117.7 and 12.2 to 12.4 with the exception of two runs...my fan was on due to alittle heat and I ran 12.7@115.xx and another time I forgot to turn the esp back on after the burnout and spun & pitched it sideways the 1st 100' but still ran a 13.8@113
