thos Posted March 1, 2012 Posted March 1, 2012 Dropped my freshly built Honda S2000 engined car off at the dyno this morning. I stayed to give it a run in to check for leaks and set the oil pressure on the dry sump, all seems to be ok. Pressures temps all looked good. So I'm back at work now waiting for a phone call like an expectant father. I'm not even too pushed what power it makes - I just want it to be reliable! Quote
Terry Everall Posted March 1, 2012 Posted March 1, 2012 That is one aweful feeling Been there, done it, bought the Tshirt etc My blade is going in a few weeks Quote
Rab (bombero) Reid Posted March 1, 2012 Posted March 1, 2012 thos, if you've never been to one before, they're not for the fainthearted! Hope all goes well and it'll be interesting to see your figures - what's your general engine spec Quote
s2k7 Posted March 1, 2012 Posted March 1, 2012 with all stock honda parts including the honda ecu, i remember putting 210 wrhp. i changed to AEM EMS, 4 to 2 and to 1 exhaust system, cold air intake and larger throttle body and picked up 22 more HP. i installed a 750cc siemen injectors, rotrex supercharger and boosted 8 psi with no intercooling and got 292 rwhp I installed an air to air intercooler & smaller pulley 95mm, boosted 12-14 psi, now @ 375 rwhp the smallest and the maximum pulley i can install is 90mm which I plan to test by summer, plan to clean the intake & thicker head gasket as well.

thos Posted March 1, 2012 Author Posted March 1, 2012 Phone call from My Dyno ... it's blown an oil hose off and has made quite a mess .... engine safe, but everything now covered in oil .... Spec'd with 400 series fittings & hose, but these engines do like their oil pressure ....... Quote
Captain Colonial Posted March 1, 2012 Posted March 1, 2012 Better on the test bed than the track...hope it's sorted quick and easy and cheap. And yes, definitely not for the faint-hearted! Good luck! 1 Quote
Pistol Pete Posted March 1, 2012 Posted March 1, 2012 Good luck, I always end up walking out on the power runs :( On the plaus side you wont get any rust :d Quote
lloydox Posted March 2, 2012 Posted March 2, 2012 sorry to hear that mate but at least the motors ok . all part of the shakedown i guess like captain said better to go there than out on track when the first you know about it is when you see a big cloud of smoke in your mirror and your engine toast they sorting it out and running it again for you? hope it all works out phil Quote
mhc Posted March 2, 2012 Posted March 2, 2012 Thos , I also had a few problems with the oil pressure being set too high when the oil was cold. Mine used to blow at the remote filter seal. I set my oil pressure at 85 psi when cold, with no excessive revs. When hot the oil pressure was only just 28 psi at 1200 rpm. Just give the engine enough pressure during the cam change hopefully between 3500 - 3800 rpm. If you see Pauls video at ty Croes you can hopefully see how much the pressure drops during the cam change. Good luck. Quote
