Well done mate, sounds like its all coming together nicely. I noticed when stripping my spare Carlton engine for that pickup that theres no baffle at all in the standard sump and that the pickup is right at the front, which would indicate the possibility of oil surge on hard starts, however mine has had an oil pressure guage from day one, has done more than a few very hard starts (I dont mess about on the dragstrip when the red mist descends!) and so far not so much as a flicker so I would say you can rest easy on that score. I think the manifold is surely what is restricting performance over 5k rpm, my car, with its cast manifold and partsbin (part Skoda!) rather small bore exhaust system runs out of puff quite abruptly at 4500. Swapping out the ecu for an uprated Cav one made almost zero difference to it! I'm now on the hunt for a Sprint sports system but will probably delete the rear box in favour of a bit of drainpipe! I may have to bite the bullet and buy just the front box and cross axle pipe from the folk in Lincolnshire, Dammit! Steve
Aha! Only been to 5000rpm to protect the engine. Need to put some more miles on it before I explore beyond this. Can't believe my home brewed manifold will flow well at higher rpm, it certainly dopesn't look like it will
Does fly up to 5000rpm mind.
My pick up is bang in the middle of the sump so is probably in a better position than the original!
If you hang on until next year you can have my sports sytem! I am looking to have a 2.5 inch manifold made up this year and then a 2.5 inch exhaust system to match next year when funds allow.
