Sweet !!!!!!!!!!!!!

 

Thanks nick !!

 

(just suprised that u coped with that umpa amout of RAW STOCK POWER!)

lol ahh yes memories

 

.. then that watermelon exel with the spoiler and Zorst came past.. not as fast tho :) :D

 

heheh that was an awsome day

lol that lancer was pacing me, xany and medicine man for a while...

heheh dam ricer !

irokin, love the avatar! :D

hahahahaha.....hey nick, don't forget me doing the "wanker" sign as well.....he thought his car was cool and loud.....until he came past me....i think i made his ears bleed....thats why he pissed off so fast....

 

if you guys hadnt been in the road i would have givin him what for....:D

lol, that would have been funny :D

I installed a rpm thingy today in my KE70

have used V-Power fuel from Shell the last month, I don't know if you guys know what that is but it's a sort of fuel with some sort of engine cleaner in it, just like you can buy external and put in your fuel

the last week the engine runs MUCH better, buch better acceleration and it doesn't lagg any longer :D

how high can i rev my 4k engine?

just tested a little today, was about 5500rpm in 2nd gear ( 70-80kph i think )

is it safe to rev it higher? I am wondering about this because now I hear a small noise from the engine, just like a broken part or something, maybe it is the radiator fan or something?

it's hard to explain because of the bad english :\

You can't REALLY kill a stock'ish 4K by over-revving, you'll just get to valve bounce and it won't rev any higher. Obviously you don't want to sit valve bouncing for any extended period of time though.

with a stock motor, rev it until it won't rev anymore, you probably don't have the airflow to get it past 7000rpm anyway

 

theoretically, you shouldn't rev a 4k past 7600, as the stock crank and rods aren't strong enough to handle that much piston speed. that's just based on a mathematical formula though

 

that being said, i have taken mine to 8200 a few times, and 8000 alot of times, but i've improved some parts (head, camshaft, valve springs). i know of other improved 4Ks that have been taken to about 8000rpm for several years without a problem. apparently if you rev them past 8000 too much, the blocks crack

Mine used to valve bounce at about 5500RPM :D Apparently it's been spotted at Revolution Racegear lately :) Hmm, Pinky with go-fast-bits? NEVER! :S

that's so bad, you couldn't even reach power peak :D have you got that bloody white thing out on the skidpan yet? i want to see SUPER MEGA 100KW HYPER FOOK-POWERED HAPPY DORIFTO ACTION PHOTO GALLERY!

Yes it's been on the skidpan once, and it bloody well flies. It's easy to drive, and I even scared myself at the speeds I was hitting, and the one time I did really lose it I was going so fast I ended up way out in the sticks...

 

According to one of the instructors who drove my car, all it needs now is an LSD and it'll be the easiest thing to drive ever :D

apparently if you rev them past 8000 too much, the blocks crack

yea...apparently.

 

Then you have Redwarf...flogged to 9,000rpm

 

I think it may be just a myth...and hell...its not like the blocks are expensive

but that's a 3k, shorter stroke means higher piston speed means more max rpm. or is rob using a 4k crank? i can't remember :D
