Project-M45 super charger (developments)

[maxfield]

That torque curve looks sweet

[appletree]

Cheers fellas ive had a realy good time doing the project and ive learn't alot. just got the few developments to do then she'll be on the road full time!

As for the mean time me dads taken me for a run in it (i'am not insured and he can drive any carthatdoesn't belong tohim) and it feels bloody quick!!! well happy

[Ant]

A video sir if you please

Racecars 2.7 charger sounds fookin awesome on the road, lets hear the M42

[Andy335Touring]

[appletree]

It is all on the standard internals yes.

The only vid i have is it on the rollers and you cant realy hear the exhuast note over the roller wine. on the road though you can hear the charger wine over everything! and then anice barking exhuast note once its past you.

I will get some drive by vids and incar vids by the end of the weekend, once ive got all the stuff sorted out.

[tim_s]

wicked! you must be grinning ear to ear mate!
now let's get those vids!

[Turbo-Brown]

Fair play dude!

Very pleased for you mate!

[e30_Turbo]

Well done dude!!

Loving the work!

I especially like the festo air line fixings, having been fitting a set to mine over the last few days they're very handy Very impressive work indeed.

appletree - that's a fantastic result well played mate - exquisite engineering too - enjoyed reading the thread
got me sufficently motivated to give ant a call about my old turd!

get those vids up pronto - that torque curve you got says it all really

[jkarran]

but heres the DYNO sheet

peak BHP- 205.5 (Red)
peak torque- 176.8 (blue)

Awesome, you must be so chuffed with that

Matts Dad here
Given the comments regarding intercooling at the rolling road, can anyone offer a typical after cooler temperature with respect to ambient on any setup turbo or s/c cheers.

[jkarran]

Rolling road is notorious for exacerbating overheating problems. Might just be worth sticking a couple of cheap electronic temp probes on it (cooled inlet charge and cooler-core fluid) while running it in on the road. It might not be a real world problem.

ps That torque curve looks awesome

[Kedge]

Awesome project mate, glad to see it's so close to being finished. Only glanced at this thread now and then but the work thats gone into this is awesome. Certainly mag worthy in my eyes!!

[CHRISP]

Well done great figs bhp and torque you must be very pleased

[appletree]

Awesome project mate, glad to see it's so close to being finished. Only glanced at this thread now and then but the work thats gone into this is awesome. Certainly mag worthy in my eyes!!

Mag worthy?? you realy think so? That would be the icing on the cake!

[Ant]

totally , TBH I'd court PPC for it, ticks all the right boxes

[stuartgallafant]

matt thats awesome, i really pleased for you. i'd love to see this at a meet sometime

[Jhonno]

thats a good effort dude! 200bhp is not to be sniffed at in an e30!

[daimlerman]

Hi Matt,are you bringing your toy out to play at the milkbar meet tonight?(please please)....well done,a lovely neat job.

[appletree]

In lincoln?? i havent heard of this? probly wont be able to make it to the meet as i'am working and ive got a different tensioner arrange ment to fit to stop the belt bow stringing on the over run and causing a vibration. the first meet i will go towill probably be a ferry bridge one but i will ne attending gaydon, goodwood revival and santa pod show for definate. sure i'll meet you all there!

[daimlerman]

Put it on the trailer and bring it up to Sherburn tonight!!

[Turbo-Brown]

The most that was recorded during my trip to Emerald was around 40 degrees C after the intercoolers if that's any help

[appletree]

So Turbo- Brown I guess that equates to a gain of 16 degrees or so, we were running 40 to 42 degrees after the laminovas. This was only achieved by changing the cooling water a couple of times and switching off the engine when not required. Obviously the oil cooler used to disipate the heat needs to be much larger, the closer you try to get to ambient obviously the larger the radiator practicality has to come in somewhere. On the plus side provided we can disipate the heat the laminovas work fine. On the couple of short runs we have done the problem is no where near as bad and the cooling water remains much cooler. Thanks Matts Dad not totally

[ShepsEvo3]

40 degrees C is the very top you should have out of the intercooler. Anymore and your mapping work will be out. Is the fans pictured the only ones Emerald used while mapping your car?

Here is a link to our "main" fan in operation...
We also have a smaller version which we use for top mount intercoolers in adition to that main fan.

Highly modded high powered turbo cars generally only see about 2 degree C above that recorded on the open road.

Nonetheless, Dave Walker is a top chap, spoken to him a few times for help with carrying out work on Emerald ECU equipped cars. He's extremely knowledgable too, you were in very good hands.

[appletree]

Just after ball park figures.
Dave had a much bigger fan available however the cooler is fitted in the std oil cooler position, you can only get so much air through a leterbox regardless of fan size. Non of this is ment to reflect on Dave Walker, as you say he's a top man, he was very accomadating and patient. I think the dyno results speak for themselves. The cooler is only 18x1x3 inches we're expecting rather a lot really, just thought we might get away with the duty cycle element, truth be known the Eaton gets exceedingly hot especially when driven towards max, additionally Matts running a recirc valve which reduces the heat carried through at tick over and light loads. Cheers Matts Dad

Cheers Matts Dad

Yes, you are right, its alot to ask of the intercooler in that position behind a "letterbox" lol. Also, the results do speak for themselves and its nice to see that the M42 can take 8psi or so without mods to the internals.

Top work though, takes alot of work to get something like this to work properly. Well done!

[jkarran]

...truth be known the Eaton gets exceedingly hot especially when driven towards max, additionally Matts running a recirc valve which reduces the heat carried through at tick over and light loads. Cheers Matts Dad

Hot enough that it'd be worth ducting some cooling air toward the blower itself to help cool the body, it doesn't have much by way of cooling fins does it? I'm thinking mine will run even hotter than Matt's if I go for 10psi as planned.

Rather than fit a bigger cooler could you maybe box in the one you have and duct some more air from under the splitter? You wouldn't need the scoop to drop very far below the splitter to collect a lot more air then you'll get through the letterbox slots it has now.

[Turbo-Brown]

I was thinking of using a motorcycle rad (someone here came up with the idea so can't claim credit for that one!) when I do my charge cooler as they're relatively compact and efficient.

I'd have thought the passages in an oil cooler wouldn't be a fine as those in a rad (just guessing mind) so perhaps the switch might make the setup more efficient.....perhaps.

[jkarran]

That's a good idea especially if you could get a pair of relatively long thin ones from something like a Firestorm.

[appletree]

Something a little like this??

its the transmission fluid cooler from a auto volvo 440. realy does look like its gonna do a good job almost 2 1/2 X the size of the other one i had so this one with the origional one still inpalce it should have got the charge temp problem sorted

ive used the standard ducting form the IS and then made some plastic sheet to make the air have to go through the rad.



I did have to make up a little bracket to swop the fan from the front of the rad to the back. while i was there i thought i would fit my spanking new rad aswell. From an auto IS of all things?? i beleive they were american spec, its got the extra cooler for the trans fluid

[appletree]

If you consider the coolant from the charge cooler will be relatively cool (similar temp I guess to the air temp in an air to air intercooler) it follows that the surface area of the water disipation radiator will have to be similar to that of the air to air cooler to give a similar disipation, admitted the thermal mass of the water is greater than that of air and there will be gains to be made there under certain circumstances. Just some considerations to bear in mind. On the plus side Matts new radiators have resulted in a coolant temp increase from 20 to 21 deg after a 20 mile journey ambient @18 deg c. A successs Matts Dad

I'am now legal!!!

fully insured with the HIC what a brilliant insurance company.

£1400

3rd party fire n theft
like for like mods if damaged/stolen
agreed value
salvage retention
legal cover
all mods decleared
7500 limited mile age

Not bad to say i'am 19 i didnt think well happy

and thats on a brand new policy with no NCB!!

last year it was £1400 fully comp in standard form with 2 years NCB

done a few little bits of development work on the car in the mean time like a double roller set up on the tensioner and the extra cooling rad. I'll post some pics later on if i get a chance.

[Turbo-Brown]

Good stuff, you're a top man for going the whole hog and facing up to the premuim.

That's not a bad deal by the sounds of it, I'm 27 with 5 years NCB and 5000 limited miles and I'm paying about 650 with all mods declared.

So's it fun to drive?

[appletree]

ya its very fun to drive espeicaly as ive been used to a 1.2 punto since i started the build and since ive put it on the road ive only been out once in the dry. It span 1,2,3,4 the other day coming out of a junction and seams very easy to light the back end up in the wet. at the minute i'am taking it steady round the corners till i get use to the RWD thing again

still got this vibration to sort out which is realy annoying me as its making the whole engine vibrate at 2.2-2.8krpm and seems to move around on load or my moving the throttle the tinyest amount, the other thing is that due to the large flat pannels on a E30 it sounds worse inside.
