erm....youve basically said it had like a litre of oil in it on the test drive! doesnt sound like big ends to me tbh. they show up more on load and over run at like 3000 rpm, pretty quiet on idle. Its probably had enough oil in to keep the bottom end lubricated, but not enough to provide...

lol just read...he put 4-5l's in? thats not low, thats nigh on empty!!!

It will run if the valves are "kissing" the pistons. It sounds the same or similar to noisey tappets....but tbh the noise in that vid is very excessive for this. Also this has high comp forged pistons?? these usually allow ALOT more clearance than stock items. Is it localised to one area of...

yes, static bar goes between the towing eyes. Legally speaking, if you go on a M.way your only allowed to go one junction, that is to say its in emergency to get you off the M.way. As for trailers, its not as clear-cut as people think. The general understanding is that if you passed your test...

the increased loadings on the thrust axis are part and parcel of a short rod. with this also comes reduced bore sealing around TDC as the piston "rocks". with a longer rod, this movement is reduced since the reciprocating motion becomes closer to SHM. This the theory obviously, and only...

I heard it was 226.9836bhp??

106mm--this a NA engine? The theory behind it all sways me away from long stroke...but im going to be testing back-to-back soon "just for fun", and to try and confirm some of the theory. Im building an "idealised" geometry F7R, which im going to run on the dyno with a standard...

as said, not enough meat between the bores to gain that much. you can go to 84mm ok, you could physically go a lil bit more but you risk losses due to bore flex and gasket sealing issues. as for increasing stroke, these engines are massively under-square by comparison to other manufacturers...

? valver and williams ports are near identical...the williams has 32mm inlets, so marginally larger than the F7P. Theres plenty of gains to be had by fitting larger inlets. Ive sold many of my ported heads using over-size inlets.

or failing that, a friendly fabrication workshop

"steel stockholders" in yellow pages is probably your best bet. go to their cutting shed, offer a mars bar for an off cut, job done :)

Standard: 48.001-48.021mm for big ends 54.785-54.795mm for mains undersize will be 0.25mm under.

looks fucked mate. rebore and high comp pistons? or another engine?!

the oil ways are on the opposite sides of the engines. better of just fitting high Cr forged pistons to the F7R, or the F4R.

pneaumatic system would be lighter and easier to design. wouldnt take much, 12v switch (paddles/push buttons) activated solenoids to control a ram.

is it the tool thats rounded or the actual plug? either way, a bar or heat isnt going to help if you cant turn the plug! get it up in the air, get underneath it, and tap it round with a chissel. Though saying that (and i dont mean this in a nasty way) if you were unfortunate enough to...

Couldnt say for sure, but probably not. A whole fiver?

I should move 2 cambridge, I miss out on all the action here in sunny Wales!

they should both be 3bar. Ive got a williams one i can sell u.

you can use the brackets of an RSI, or volvo 340 to have JUST the alternator, and with this use a shorter belt. use a 1.2/1.4 rack OR for "quick rack" use a williams PAS rack with the pipework removed (ive got a couple for sale if you need one).

Idle will be pretty perfect no matter what the cams are...the ecu doesnt have the same operating "down-falls" with that respect as an OE ecu. Jenvey are best/proven and are good value for money. Only damage will be through faulty fitting, or inaddequate mapping...otherwise theres no...

thats right....the grpA cars running solid mounts and rose-jointed wishbones, were a whole host of trouble *roll eyes*

negative edde... A race car will run part economy on non full load conditions. Consider a Le Mans car, they run circa 16:1 AFR when not on WOT....helps conserve fuel. As for economy v's power, its not RPM based, but load based. You only need max torque on full load. Any thing else can be for...

why would you run megasquirt edde? Have you ever used it before?

i like smiling

I think this comes under the old cliche of: "if asking on internet forums....."

never say cant :)

anything is possible if you have the skills...

yes..hence i said better, not perfect :p

the RS ones seem to be matched to the head better as std. Ive seen about 8bhp gains with RS items, and 10-11bhp on non-rs ones.
