how do you get traction???

beers

 

Its an older model Gtech - bummer with it is that you can't do 1/4 mile & 0-60 on the same run.

Did try a 1/4 mile also but have not managed to better previous time.

 

Swoope! I use Bridgestone S 540 R-tires 245/40-18 and always do a strong burnout to heat them up. Start at 5500-7000 rpm depending on traction on the road.

Brettus! I only managed 6.15s yesterday but my 1/4 mile ET improve from previous 14.76s to 14.69s at only 92.5 mph or 149 km/h. Soon out testing again, lol.

interesting,, i have never tried to heat them... but it is warm here...

best to 60 6.1sec. 1/4 14.45@94.5. that was before the prolight flywheel...

i have not figured out my new clutch... in time...

beers

 

just for fun

with full tank of gas & a poor launch - not a bad trap speed though .
0-60 was 6.39 on this run so theoretically with my best 0-60 - 1/4 mile should be over 1/2 sec quicker than this .

 

So, what is everyone's best time in the 400m in GT4 with the RX-8?

 

who cares... so far everyone is in us miles... which is nice, that we are all talking the same language..

i dont know how to accept the friends request..

beers

 

in good form as usual Ike

 

or he could buy a g tech or g timer. and have something to add..

i would love to know what your new car does... it would sadden me, but would love to know...

beers

 

Well you wouldn't find out what it does from a consistently inaccurate G-TECH reading. Just for fun, find a friend with one and put them both in the same car. Its amusing.

 

Here in Sweden i have done some testing comparing the old vs new G-Tech. I find out that ET was pretty much the same but mph do differ up to 4 mph.

while I realise that Gtech is not a drag strip & never will be i've seen independent tests done that show they are accurate within 0.1s - certainly good enough to get a good indication.
Also re the top speed - note the change into 4th right at the 1/4 mile mark - that is hitting the rev limiter which on the speedo (and scanalyser) is 162 km/hr (101.3 mph) so it will be fairly close also.

 

i guess my point is i cant just go out and rent a drag strip or track when ever i want to test something...

but if i could afford to rent the track everyone would be invited!

beers

 

Why would you need to rent a track? Most dragstrips have test and tune several days a week that are open to the public.

 

tend to be on the nights i work.. and it is much more convenient to do it when ever i want... also the track will not give you a zero to time..

beers

 

Soon (next week) i will finally driving my RX-8 again! It was 7 weeks since my gearbox went caboom and $4300 of gearbox parts later i will have it on the road again. Yes it's a guarantee work. Only one more mod is being done that is a ACT ProLite flywheel with stock clutch. Goal 2007 to go under 5.50s 0.60 mph and a 14.2s 1/4mile with my N/A rx-8. Oh i should also mention that i gonna have a Haltech Interceptor X and my own Ferrita full exhaust system with a www.petergproductions.com headers. That's all (i think) right now.

Hey guys, I'm going to california speed tmrw and I wanted to mix a bit of 110octane into my gas. Does anyone know how much to mix while running the rb race flash??

 

The times are OK, its the MPH that are not comparable, since they are nor calculated the same way.

At the track the MPH is an average over the last 60ft or so.

On a G-tech its the actual MPH at the end of the 1/4 mile.

Thats why the g-tech always reads 4-5 mph more.

 

what makes you think the 110 will make any difference ?

 

Why wouldn't it? Higher octane = more power doesn't it? Yes it does.... so.... what's the deal?

 

no it does not.. sometimes less is more..

beers

 

Nope. You lose.

 

hm... less is more, 100 octane? =/ i knew i'd stand corrected in the end. i was hoping i'd understand though. oh well time for some hard researching again.

 

Octane only speaks to the fuels resistance to detonation. This allows you to run higher compression and more advanced timing. Especially in Forced Induction. Since you are NA, and the computer controls timing, there is no reason to run super high octane. It is actually harder to ignite, so it ca gum up your engine if all the fuel is not being burnt.
