Wow...just "a bit" of a difference. Hah! Looking good!
Which reminds me...I need to start tearing into the M62TU I pulled out of my 540iT...

Thanks everyone it's been a long task but I've loved doing it!
The car will come in the garage tomorrow once I've made space and I'll start pulling the 7 cylinder out its done its job
will be a week or so till the standalone arrives so waiting on that so not a massive rush to get it in can take my time on it really

I'm definitely suffering from engine envy

Managed to get the 7 cylinder out yesterday and get the gearbox mounted onto the new one. The gearbox just needs cleaning up and so does the bay now
Lights on, nobody home
Wow, that's some tight confines.... Do you crawl in thru the sunroof?
Is your buddy brushing his teeth there??

Yeah it's pretty tight can just get out the drivers door.Originally Posted by Mach540
Haha no he's eating a chocolate bar
managed to get the gearbox cleaned up last night

Well today I had the engine tuned it's been running for about 3 weeks now in standard trim and I've fitted the supercharger over the last few days and here's the results 385hp and 422lbft (the rpm scale is out on the graph)

NICE!! What does the (332) mean?
Member
That's wheel hp I think. 16% loss I saw on the screen

Nice low rpm torque! Are those crank hp and tq?

Nice numbers! I plan to dyno my car in a few months with my 4.5 and jag supercharger
E85 fueled, Eaton m112 supercharged 4.5L M62TU, TTV racing flywheel, Spec stage 2+ clutch, 88c thermostat, eibach sway bars, wavetrac 3.15 lsd, m5 steering box, Quantum 340lph fuel pump, Dinan camber plates, some powerflex bushings, Supersprint headers, M5 cats, 2001 gas pedal upgrade and many other things done. all diy by me

385hp crank. 332hp at the wheels I think works out as a 16% drivetrain loss.
How hot the manifold got i think it needs something more free flowing to free more horses up the tu manifolds are just rubbish.
The torque feels a proper animal being that low down
Member
I can't remember the specs of the bottom end build on this one Jon. Are you doing anything to alleviate the normal bottom end problems that seem to occur with serious low-end torque? You're making a fair bit there!
Member
All I've got is widened ring gap and decompression rods what else should I of done?
Member
Personally I think that should be all you need. This should be excellent!!
Member
Phew! You had me worried for a second then! I did a compression test as soon as it ran with the standard inlet on so I have something to compare it too if I do one at a later date. It'll allow me to see if there is any wear to the cylinder walls or not over time
Member
Yeah, I just couldn't remember what all you had done when you put this one together. Sorry for causing alarm!

Is the torque also corrected to be at crank? Good numbers regardless. Crossover point of torque and hp not at correct rpm, that is why I'm asking.

HP and torque are on different scales. I think that would roughly account for the discrepancy.
Member
Not a problem it's been a stressful day putting the engine through its paces I'm still on edge now!Yeah, I just couldn't remember what all you had done when you put this one together. Sorry for causing alarm!
I would imagine so yes.
The rpm scale is off I'm not sure why. Limiter is just over 6k

Aha, yes. Scales are different.

Yeah screw the crank stuff, it's essentially meaningless, but that is some good wheel torque! Coming through on the promise of low early torque delivery. Over 400wtq from 2500 to 4700ish (maybe just a little different if the rpm scale is off... But close enough...), that's gotta be fun on the street.
