yeh lookin at the haltech manual last night i think i know how to do it the vipec was looking half interesting there for a second, but noooo bingoooo

f**k, that really sucks is it only in the v88? or is it in all the vipecs?

so they actually have one hey, interesting. How does it exactly work paul?

Firstly, are there any ecu's on the market with an in-built fuel pump controller? Something that will regulate the voltage at differeing rpm, so the pump isnt running full noise 24/7 and heating up the fuel. Main concern is big pumps in street driven cars. I know aeromotive do a unit, but its only a 2-step i.e only regulates voltage based on 2 rpm inputs, well thats my understanding of how it works. Is there anything out there that gradually increases/decreases voltage in relation to rpm? If you run a big pump/s, how do u combat this?

Progress has been slow...

not even worth running the gas on the transbrake to get it off the line with the meth? i guess its a choice of running the gas with meth and possibly risking an engine or playing it safe with the 109, i guess its a no brainer hey so what ecu/ignition/timing setup is on it? (sorry for the gazillion questions lol)

i see i see. have u looked at other options like a barrel water-air or similar? just some ideas as it seems ur going pretty out there and prolly chasing every little bit and i guess a std cooler setup is going to be alot heavier and have alot more length of piping

other intercooler setups i have seen when the engine has been run on methanol, have run no intercooler at all, only a pipe joining the plenum to the turbo like this:

what was the reasonin behind leaving the air-air intercooler on with you running methanol? just ignore ash and the other twats, and kepe posting specs etc for the rest of us!

Dont worry rob i really do appreciate your pointers as you have been building these things for years and have great results, clearly shows ur a wealth of knowledge. U prolly didnt see my post just before, but im using a convential cap head bolt, not a tapered bolt. I can see the issues ud have if u used a tapered head bolt though. Yeh i was going to wait and test it on my own car but its getting some chassis work done atm so it wont be ready to use for sometime, also i'm working with a workshop who have cars available to test on and if testing goes to plan a drag car to test on half way through the year. I do see issues already like how are we going to overcome differences in thermal expansion (most likely by running non-std clearances), line boring with the 2 different metals and many more, but like u said thats what the testing is there for! Thanks for the help so far, i really do appreciate it

That and relying on someone else to line bore it properly are my my greatest concerns lol i dont actually use tapered bolts, i use a proper cap headed bolt. And for the 5 8mm bolts on the diff side that u need to tap the block for, i use a special half headed bolt so it leaves enough meat in the plate when its countersunk. I decided not to use a tapered head bolt as a normal square headed bolt has a greater and more even surface to clamp down with.

Would there be more than ~20thou variations between the blocks though? There's 20thou clearance around all the countersunk holes, so there is room to move in that. How do you go about that? Urs would be similar with the 4 bolt mains ur using. yeh that's something i'm considering. Provide a bottom end with atleast bearings in and clearances set.

The sides are machined to size on the cnc and then the radius' are cut on the line borer.

they dont come std with them so f**k them i say

Im not an engine builder but i have discussed this with one and like adriano says its adjusted via the thrust bearing thickness or width of the cap. The cradle has zero effect on it other than width/alignment of the middle cap. So it boils down to how good the machinist is. Does that sound about right to you rob?

I posted some pics of a sump i had done recently but cant remeber where i posted them, so here's some of the actual external pickup

Yeh its mainly used for 2d based drawings.

yes it will

quantum engineering in brisbane, they are aactually to suit a mitsubishi engine (forget the code) as you need to match the ring thickness up

Good luck paul and give it the beans!

i stopped reading after he asked if itd work...

isnt legal height 100mm? if so 7 mm under that 110mm measuring wheel would actually be legal by 3mm...

awesome helpful info there again ash! no it wont work, u can try but u'll do more damage than good. its a head off job as like fineline said u need to convert it to solids.

i see in ur sig that u've got a fine example!

see how versatile they are? They wouldnt have been used in sooo many things if they werent as awesome as we're making them out to be
