nice going! what torque are you producing?

I'm making 214BHP at 7500RPM on schrick cams with ported head and ITB's (when the fukcer runs that is..) torque curve kicks in at about the same point as on 2.4 mani, but is maintained much better to the red line.

Good to see you are up and running. What are the issues?

I forgot to ask for a dyno plot when it went away to Troy at Northampton Motorsport, as at the time I was more concerned as to why it just wouldn't run, so numbers wise I can only go on what Troy said - ~165ftlb 214BHP Issues were:- Trigger disc I modified didn't work despite being done correctly. Closed ECU meant I couldn't tweak crank sensor position and Troy couldn't do it either because unlike a lot of stand alone ECU's the Pro4 has less range of adjustment for this. Had no choice but to buy new revised trigger disc. Dodgy wiring on TPS caused by the former owner (Thorney Motorsport) scraping the insulation off the wires to calibrate it rather than doing the job right with some break out cables. Several issues with poor idle / tip in caused by over tightened nut on butterfly valve, poorly balanced throttles, the fact that turning lambda control on makes it run rougher anyway and closed ECU means a trip to Northampton to turn it on/off for MOT, vacuum leak caused by aging slightly enlarged red hose on the end of the vacuum "rail". That last one really screwed me as it was very intermittent. But by far the biggest issue is my total lack of arsedness to pick up a spanner when no one is paying me to do it :-D Really at work I can and do sort a list like that out in a day, instead it's took six months! Lessons learnt are buy brand new kit and get open ECU just in case. (Sorry for the thread drift Speedster) Back on topic, it would be great to see a homebrew flowbench.

Such a shame they lock the ECU. This was the main issue with there products going back to my kit car days. A good gain over your last visit to Northampton Motorsport.
