RSL is one of my customers and a good mate for over 20 yrs

so the cars in oz or nz? rsl just did an e30 last week along these lines never saw it, and if you need parts for the dsr thing i have boxes of blown up ones you can have

what diid you base the header length on

pin height is wrong only a b18c piston or mitsi but you still need to measure that v12 piston for me

just the front at the mo the disc's are 360x32 yet to do the back and will when ive done the m5 rear end and sub frame etc rather than do things twice, it stops well but not as i would like it thus the pedal box is next

ah my bad didn't see that yes i need the same but a large case around 3.5 upwards the medium 4.1 im running is great with 8500rpm but im not aware of a large case that ratio.

oh really? doing a comparison for e34/e28 there's 265lb difference unless there's different curb weights model based if you changed the diff ratio you could make better use of the gearbox staying in 3rd points too a tall rear end.

whats the weight differance between the two cars? i noticed at the topend he pulls you back in

Thats not how tuning works or how to make power try this little formula i use to make headers p=primary header length p= 850xed( 180 deg plus number deg the exhaust valve opens before tdc) / eng rpm you want to work it best at ( and i dont mean 9k! This gives the primary length header id should match port id and running 6-3-2-1 gives a broader power band and helps cylinder scavenging also running stepped tubed headers gives a greater power band. Where the 3-1 come together you need to run a merge cone also coming into a merge collector stepping down then up again around 7-10 deg the actually main system for yours a single 3" is fine and n/a will do 350hp turbo ill push 900hp. Now cam position is also important and i dont mean drop it in the hole and its all go there's free power to be had there as in what center line is each cam sitting at? plus or mins a few deg makes massive differences between good and great power. Ive never been a fan of generic cams unless the head is done to suit reverse engineer it by doing the head first or at-least flow bench test it to see where it works the best,just cause it has cams doesnt mean it work better. eg: if a head has peak flow at 10mm lift and the cam is 10.5 you can drop air out of suspension killing power big time short of me designing what you have if you dont have answers for any of that then who knows what you may have or could end up with. ps: exhaust isnt the only thing that limits topend where would you like me to start on that topic? Seriously unless you build an engine from the start knowing what your trying to achieve even the calculator wont help you, even with an error of 10% your still pretty much the same power as the motor was stock no matter what way you look at it.

Ive seen his car go and power to weight is a good thing im basing my findings on what i do day in day out and wouldn't it nice to find another 30-40hp hiding that maybe over looked? im sure you would be even happier hay just trying to help Brent there's many ways of doing things....A

i dont dought it doesnt go and its around the same power as my m50b25 with similar work but its still about the same as the engine was stock im sure there must be more in the tune or somewhere, be interesting what an exhaust does that factory 286hp was on a factory exhaust so bmw says. 188kwx1.15=216.2kwx1.34=289.7hp

hay brent if ive got this right and not picking but the m88 stock was 286hp which working back and converting to kw wheel its 248hp wheel or 185.8kw, ive seen a few mates cars come off gavins dyno and 15% to the wheels is pretty much bang on just a thought for work done it doesnt seem to add up unless the motor for the 160kw was tied but still makes the power same as a stock m5/m635. something isnt right there should be alot more in it and not just in need of the exhaust, cam timing to tune is too soft? http://en.wikipedia.org/wiki/BMW_M88

A mate came around hm with a v12 merc that pagani use in the zonda? Its carbon foot print was so bad merc used water based paint and recycled plastic and the killer was the bio degradable wiring and from 96 to now every wire has gone brittle and turned white!! It used 20ltrs per 100km still stock hp was 450,i like the v16 but wouldn't mind the M1 sitting above it.

buy a can of engine start and spray it around all the hoses and intake manifold if there's a leak you'll soon find it.

i got some 850cc for bugger all off ebay

im building a pedal box to bottle onto the firewall same as the booster using a balance bar and two wilwood cylinders im running the e38 master and sick of inconstant brakes.

6x custom wossener pistons landed including postage 900nz, give me the pin height and ill give you the details they should be 22mm pins

if the pin bore is the same and height then yep and cheap

even under-drive you wouldn't gain a lot but cooler in the back would have a lot less drag. as for pistons that's easy i just need bore size and pin height im using mitsi evo pistons in mine

i like the way you think outside the square aircon pumps don't like high rpm thus why they kick out when drop a gear to pass someone, i think a air/air is the simplest and room is a major factor to consider. a single is easy enough it just comes down to how much power your after im doing a v12 Toyota in a off-road truck but there's also a lot more room to deal with, if you go for a water/air put the heat exchanger in the back.

that depends on where your going to mount it, how about 4x gtr turbos? cheap and easy to find

now your talking a nice big pair of hair dryers would top that v12 off nicely

This is why i pulled all the info i had on here once before. I think you'll find very few people in the performance industry are willing to take their free time or lack there of to help and play show and tell and doing so not to generate work because im not lacking in it. If knowledge isn't shared it gets lost and no one benefits im not trying to be marter just trying to shed some light in hope its of some help to whoever it may enlighten,i enjoy playing in my spare time with BMW's and will continue to do regardless of idiots.

Going by all your posts here and on other threads you have so many positive things to offer now quick run along ya mums calling you for bed time......and try using spell check.

ah dont know if you noticed but the motor is built ready to go, have yet to drop it in due to the fact i spend my days do this for customers as well if thats ok with you? So unless you want to pay my bills as well and shed your profound know how and do what i do for living as well as you seem to have an opinion and thats about it, abit like butt holes everyone has one. As for being ambitious this is a tad tame compared to what i do all day. Please feel free to share your accolades for all to read i look forward to it.......
