the lightweight flywheel will definately drop that by a few tenths .
Don't know how anybody ever got under 6.0s for a stock 8 as quoted in some mags - not even sure I can make it with all my mods.

 

i have done a 6.1... with out the flywheel... start dropping the rear tire pressure.... launch at ~4.5k and feather the clutch dont dump it...

whenever I feathered the clutch my recorded times were worse. I dunno why but I am sure of that... dropping the clutch and controling wheelspin with throttle gave best results.

 

you do know that you can control the wheels with the clutch, and the throttle is controled by the ecu? as in fly by wire???

past motorcross habits for me.

beers

 

Tried a 1/4 mile run on gtech for the first time today .

14.60s @ 99.2 mph .

Think I could have done better if I had let the clutch out all the way sooner as I don't think I had any wheelspin.

Was a little dissapointed in my elapsed time (with all my mods) but my trap speed looks very promising

Will wait till after my dynotune before seeing If I can better that.



just did another run :

14.46 @ 101.7 mph


Have tried getting wheelspin but I just bog it down so these runs are done by feathering the clutch . Also I hit the rev limiter for an instant in each gear with this run . There are better times to be had I'm sure but my clutch is starting to hate me

 

my best is a 14.6 @ 94.6. so i think you are doing pretty good.... the flywheel makes a big differece in the trap time!!

beers

 

brettus what are your modifications, your trap speed is indeed promising... 4-5mph more than most of us...

 

check my garage

 

I just had my 2.5" Ferrita rear muffler with 3.5" tips installed today! It sounds great, with almost stock sound at idle and a nice deeper throatier growl when you floor it! Dyno test on Wednesday.

Seems harder than I thought to get a better time than the one above . Can consistently get over 101 MPH though so it should be possible for around 14s flat with some more attention to tyres etc.

Dynotune does not seem to have done much

 

... ? What does that mean? !'m from Sweden!

Thats a good run. And u just have an intake and exhaust? Im new to it too, and I cant seem to get better than a 14.7. How are u shifting. I havent lauched at high rpms like you. Maybe I should try that.

 

Today i have set a new personal best 0-60 mph time. The new one is 5.86 with 60ft of 2.10s 1/8 mile is 9.25s Nice sunny weather but cold +4 celsius Launched the car at 5500 with no wheelspin at all.My 4 mods are: Shell VPower fuel Motul oils and front race catalyst with a 2.5" front silencer.and a big rear silencer from Ferrita Sweden thats all. Next week i will be mou nting my prototype headers.

thats an awesome time Lasse - congratulations .
The temp will be helping get the AFRs a bit leaner .

 

Very nice. What was your 1/4 mile time?

 

nice time. pretty cold up there... we get 15 C now in greece and we are freezing all of a sudden lol...

 

Thanks Brettus, G Rover and RotorManiac! I am in a "boosted" mode and gonna try to squezze every hp of the Renesis engine (280+hp) and then tear it down and do a stage 1 streetport. I haven't the chance to do a full 1/4 mile becausse of limited length of the road. I will do some runs this weekend. hope to go 14.5s or faster. What's the fastest 0-60 mph with bolt on mods right now here on the forum? That's without slicks but ok with R.tires!

/Lasse

 

Have not seen any better than your time ..........
Will have to see what I can do on a cold morning

 

We had our car at a show at Irwindale for Kumho Tires. Also got a chance to make a few passes on the 1/8 mile strip. Car is set up for B Stock SCCA autox, so mostly stock. Has KN drop in filter, Borla muffler and Koni shocks. Alignment is set up for turns, around -1.8 camber in the rear, so the launch is not great. Tires are Kumho V710 road race tires, 245-35-18.

RT .519
60' 2.185
330' 6.180
1/8 9.448 @ 74.91mph


Around 6:30-7:00pm would guess temp was around 70.

 

Nice numbers Ulllose! Seems that my car has some more modifications that's why it's faster. Would be interesting seeing your 0-60 times!

/Lasse

 

Please please please stop comparing G-tech times to real times at a track.

 

hmmmmmm better try again Lasse

 

nice,

but what are you using. does not look like a g tech or a g timer?

beers

 

Congrats Brettus! Nice number and still 0-60 mph? Did you try any 1/4 mile? I will be out on the streets today with my G-Tech Pro cause it's a sunny cold (+3c) day here in Stockholm lol.
