bhp = torque x revs / 5200 roughly i took the torque drop off point from rr day and used a conservativetorque figure from the recent power run so 205 lb ft x 5500 / 5200 = 216.? i the torque ctually rises to around 210 by 4500
iv been for a drive today and come to the conclusion the graph is WRONG no way does the torque drop after 4500 rpm if anything it pulls harder in which case it put out around 215 bhp with a huge surge of midrange torque
there is pete im not talkin about that m8 its higher up the rev range it just dies it doesnt feel slow when drivin though another odd thing is the torque sheet stops at 5200 rpm its all a bit wierd tbh im chuffed to buggery with the peak torque figure though hehe
how does it do it ignition timing or fuellin or both??? il ring collins in the mornin and talk to them ps i left my old torque sheet in mikanichs doh hehe
it was just a power run jason it was mikeaniks in congleton he was confused by the schrick lol i dont have cams so should get a drop when the schrick opens upto 4600 rpm the graph is fantastic BUT it tails off then as opposed to pre schrick and chip where it tailed off at 5500rpm it nails the bhp figure i only got 188 bhp if it carried on till 5500rpm as before i should get 215-220 bhp
possibly justin the chip deffo smoothed out the drop when the schrick switches il speak to collins about it see what they say ps ingham has the same chip and his figures seem good at rr day [ Edited Thu Feb 03 2005, 04:06PM ]
MY CAR HAS GONE ALL DERANGED I GOT A POWER RUN DONE AND THE RESULTS WERE ERM SUPRISING PEAK TORQUE IS AT 3300 RPM AS I WAS EXPECTING DUE TO THE SCHRICK BUT I WASNT EXPECTING 235LB FT !amazed !amazed WITH A HEATSOAKED ENGINE THATS HAD 2 HOURS DRIVING BEFORE GOING STRAIGHT ON THE ROLLERS thats up from 187 lb ft before the schrick and power chip thats the nice suprise now for the disapointing figure of 188 bhp down from 198 i know this is due to the torque dropping off rapidly from about 205lb ft @ 4600 rpm to about 190 lb ft @ 5200 rpm i assume it keeps dropping but strangely the graph st
what reg is urs early (pre p reg i think) had an idle stabalizer valve this gets dirty and causes eratic idling vrs do idle at around 1000-1200 rpm on cold startup for s few seconds
i got an off the shelf chip fitted for £176 but stealth do 1 with a remap for about £400 i think imho they have great grip for fwd but mine does have uprated suspension [ Edited Wed Feb 02 2005, 08:42AM ]
AMG get 738lb.ft. out of the V12 Merc and BMW push over 400 out of their 3 litre (alright it is a diesel!) they have huge displacement and diesals do make silly torque figures
