SLO-030 Posted February 18, 2009 Author Report Posted February 18, 2009 dunno. i got rid of my tach a while ago. havent been in any 100kay zones to check anyway. Quote
Jason KE30 Posted February 18, 2009 Report Posted February 18, 2009 When cruising at 100 in 4th gear my car does 3000 rpm. So yours should be something like that. Quote
SLO-030 Posted February 18, 2009 Author Report Posted February 18, 2009 yea, i thought thats what it did with the 4spd when i had the tach in it. with the 5spd it would do like 2000rpm maybe? Quote
trav_555 Posted February 18, 2009 Report Posted February 18, 2009 WHat man in my ke70 5speed it does 3200 at 100km/h!!!! Quote
trav_555 Posted February 18, 2009 Report Posted February 18, 2009 i reckon, why would it be doing that? probs why it uses so much damn fuel!!! :bash: Quote
Jason KE30 Posted February 18, 2009 Report Posted February 18, 2009 High compression might be makin it do higher revs... Quote
trav_555 Posted February 18, 2009 Report Posted February 18, 2009 really? cause it did about that with old engine and its the driveline that changes the revs Quote
Roo Posted February 18, 2009 Report Posted February 18, 2009 WHat man in my ke70 5speed it does 3200 at 100km/h!!!! lol your lucky, my 4agze does 4000rpm at 100km/h!! Quote
SLO-030 Posted February 18, 2009 Author Report Posted February 18, 2009 High compression might be makin it do higher revs... BA BAWM..wrong :bash: really? cause it did about that with old engine and its the driveline that changes the revs Yea, its the gear ratios which change the speed of which the wheels turn. The lower the ratio the lower the wheel speed therfore needing more revs to turn the wheels at the same speed. Get a higher ratio diff if you wanna drop your revs. Quote
Falken_KE30 Posted February 18, 2009 Report Posted February 18, 2009 Still no pics with a SC12 on the side of a 4k and inside your engine bay......... Quote
Taz_Rx Posted February 18, 2009 Report Posted February 18, 2009 Why are you using a 3k head on a 4k (ie high comp motor) for corced induction? Or is that just an interum motor unitl you get a charged 4k happening? Quote
greenmac80 Posted February 19, 2009 Report Posted February 19, 2009 interrum head until he gets the 4k head cleaned up. Quote
SLO-030 Posted February 19, 2009 Author Report Posted February 19, 2009 As Luc said above. thats what the engine had on it when i bought it ( unbeknowns to me) so i slapped it back on and will get a good condish 4k head from UPI and get it machined so its dead flat and do the valve stem seals. Raven was sayin a while back that a 4k/3k head combo with an sc12 tuned right could put out a nice torque figure. Quote
