Thorny stage 2 conversion

My CSL with ss race backbox made 355 bhp on the dyno (66k miles) .
I added the SS headers and SS mid pipe .
With a remap the car made 374bhp on the same dyno .

What CATs are you running?

Watch this space tho.....

So your standard manifold engine pulls stronger than marks lighter car with ss manifolds?

If so, My point I think proved that they are a waste of money!

PM me what you are doing Ad? and your package is in Micks

So 19bhp from manifolds mid pipe and remap.

But companies quote that much or more from just a remap alone. Either the remap figures quoted by nearly everyone who remaps M3's and csl's in the country, are not 100% true or the SS manifolds do diddly squat.

Just look how you can get 22HP and 58NM in a CSL.

PS : for years it's a joke with a best friend of mine... the gains this company is advertising

Still OEM cats .

I did not gain much Peak HP but the car gained alot more HP and torque at mid rev range over the oem setup .

A first my car was slower than my friends CSL , i could not follow him in a straight line (both stock) .
Then i added the SS stuf (no remap) and he now has a 3.9 diff .
And the cars were dead even in a straight line , so i think the ss headers will add a few HP's .

Company's claim +20BHP from ecu tuning , headers should be 10-15 bhp , so if you should believe this , with a remap and SS header you would get a +390bhp CSL ?? I don't believe that , sounds a litlle bit too easy .

I have been told by a couple of engine builders that they are a waste of time, my car has standard airbox and standard manifolds against Marks CSL type airbox and SS headers....will be interesting when they go on the dyno

[shimmy]

my gut feel is the following - no science to it but just my impression

1. all the bolt on mods+map aint gonna get you more than 275bhp from stock 255 bhp on a good day

2. with race cams and stronger engine with higher rpm + map youll get to 390 bhp

3. full on race engine with free flow exhaust and remap will get you 42bhp plus

4. lawsy doent like being called a Manc

And since this is an open forum I will state my thoughts!

Sal and Evolve should be getting along, as he owns the company

You mean Sal and Thorney

The thing im confused about with the SS headers, is that the power gains quoted on the SS website, was for the LHD M3s, which is completely different to the ones made for the RHD.

The problem with these power gains from bolt on mods and remap, is that people add each mod and believe thats what they will gain.
If cats give 10bhp, headers give 5bhp and a remap gives 20bhp (just random figures), then you will not gain 35bhp. The cats on their own would give 10bhp. But combined with other mods, its not as effective.

I think the 30bhp gain is possible with the full exhaust system, and remap, but not on a CSL IMO. The CSL has better cams, exhaust and airbox from the normal M3, to increase the extra power.

I could be wrong though. Here is a mates car, who has shrick cams, full system exhaust and remap.



So if a standard M3 has about 330bhp, then his power increased by +33bhp. 3 bhp increase just on shrick cams, if remap and full system exhaust gives +30bhp

Even though he has all those mods, i still kick his ass 1460kgs vs 1650kgs though

I hope you do gain 30bhp and have 380-385bhp, that would be awesome for an M3.
