hi gs

I would love to claim that the BHP figs are at the wheels , but alas they are corrected flywheel figures . We were hoping for around 600 bhp , but we are settling on the lower figure in the interests of reliability and being able to bolt on the kit without need for internal modifications. Still , +150 ish bhp over stock is not too bad I think considering price and bolt on nature , would you agree ?
thanks

release of kits within 14 days if all goes to plan :wroom:

I agree, you have well over 100 hp gain at the wheels, and hopefully a motor that stays together. While 600 is a nice target, in real life it doesn't really matter. 599 or 601 are the same, and 554 will be good if the price is right!!! It is hp to the wheels that count, so I don't care what you "factor" back to the crank. Traditional RWD uses around 15% drivetrain losses, looks like you are using about 20%.

Besides, we only need at least 507 at the crank to stay competitive!! :biggrin:
Regards,
Jerry

some more info for you regarding the recent dyno run etc

- Sun Diagnose Dynamometer, HP is according to DIN 70020,

-Power at wheels was 388,5 kW at 6650 rpm
-air pressure was 1007 mbar, air temp 25 degrees celcius.
-max temp recorded after chargers was 58 degrees c and corresponding intake max temp was 33 degrees.
-max boost was 0,515 bar
-before figures on same bench was 290,3kW, but 1006 mbar and 27 degrees celcius

Thank you so kindly for the updated info.

Ive been reading all your responces and heres my outlook I drive about 500-1000 miles a week yes in my 2000 m5 its my daily beater as it is since i bought it used with 18,000 miles ive had alot replaced including a motor and sub frame ok so supercharger i would love to do one it would make me so happy to be able to smoke anyone with a e55 03 and up lol and i guess with this kinda power new m5 too now i got a question ess ca auto are you the same company Its very weird that your kit resembles the AA kit please explain I want reliable horse power racing e55s and vipers is fun you might even beat em by a good amount but they can do it every day will i being i make 500-1000 miles a week be lying to myself that its possible without having to support my car like its a mortgage?

hi

because of the very design of the M5 engine and thge restricted space issues , any charger kit that is developed , by whomever , will be very similar in nature , layout and componentry .

Whilst we sell ESS and active products , this particular kit is in no way associated with these (very good ) companies .

I thought the CA auto and AA auto kits where being built and designed side by side? Only difference being the CA kit has no intercooler?

Check the pics in post #179 in this thread.

I see a HUGE intercooler.

Sounds intresting .

I have a question, what parts do I need before installing the twin supercharger?

for example, CAMS, Pistons etc ..

As I understand cams are optional but you don´t need new pistons.

 

[Jayson]

Bolt on means just that, pistons and cams would not be bolt on as you open the engine. So all you need is the kit.

good day guys

to re confirm some points for you :

- as clearly explained ,our kit is in no way associated with any other tuner , we have never said anything to the contrary . it is inevitable though that all such systems will be very similar in nature and layout.

-this kit always came specified with intercoolers from the start

- No internal engine mods are required , unless you later wish to raise the boost pressure for more power / torque

all the best

Thank you for clearing up but don’t you think that M5 has high compression engine
That’s why I asked you if it needs to reduce the compression..

I know Im bit late here and I didn’t read the thread, it might be more details but I will go through and read the whole thread …

Some of the information may be proprietary for now, but forced induction causes a lot of heat and raises the effective compression ratio. The E39 M5 does have high compression for this application, 11:1, but by using relatively low boost, say 6-7 psi. the motor should be able to handle forced induction. By way of comparison, my 2.2L 5 cyl Audi turbo has 9.3 to 1 compression and runs about 12 psi from the factory (it runs 20psi all day long because it is very strong and designed for forced induction from the outset). You also need a VERY big intercooler to help manage the heat. And this setup has a very big intercooler. But be very, very careful about turning up the boost. At a minimum, you would want some water injection to further cool the intake charge. Realistically, if you want more boost, you need to lower the compression some.
Just my $.02.

Jerry

Jerry is 100% spot on with his comments and advice , thanks for posting in such an informed and helpful manner :cheers:

One of these kits is being fitted to another M5 as we speak , and you can follow this on this thread http://www.m5board.com/vbulletin/showthread.php?t=66242

"You also need a VERY big intercooler to help manage the heat".

Use a air-water AFTERCOOLER and problem solved.I believe intercoolers work best with turbos.

I have some questions for you on this kit

1) For aprox 1100GBP per year you are offering a warranty "depending on cirsumtances and level of cover required". Can you elaborate more on this? Are you talking about covering the entire motor, just your parts, etc.?

2) Why the change from rigging tubbing from the IC to the plenum, to a flex tubing from the twin S/Cs to the intercooler as seen here as an example:

What kind of flexible tubing is that? How thick is it to be safe from sagging and penetrations from debris? I realize it will be covered by the belly pan and probably safe from all penetration, but after seeing the how AA kit used all solid tubing underneath (and still being covered by the belly pan), I'm curious as to why you chose to go with flexible? Solid just seems more "safe".

Did CA experiment with all solid tubing underneath the car?

3) Your website lists "rear subframe strengthening" for 395GBP labor and parts. What exactly is done for that? The price seems fairly inexpensive.

 

[CA Automotive]

hi , thanks for posting . In reply to your points

1. The warantee is not available at present through CA , though you may well be able to arrange this as a private insurance matter . In short we were let down by the underwriter we enquired with

2. Flexible tubing was used at initial stages to determine best routing ; it is now almost all solid tubing

3. the sub frame mods are strengthened plates and brackets that are welded in place on the car

many thanks

Looking Good

Despite any grief you have gotten.
Please remember this guiding fact:
W/O inventors and HP buffs like you none of us would have any options for our beasts. Keep up the great work. I will continue to follow your and others progress in this areana as I will eventually be either supercharging or going the turbo route on mine.

Best of luck and continue the excellent work.

BZ!

many thanks for your kind coments warhaven , we greatly appreciate them

Well I was entertained for a while but what happened to the new posts maybe we need to call the mythbusters hahaha:M5rev:
