Re: Hartge M5

since found out that Hartge used special cams and a different exhaust plus I imagine alterations to the ECU to produce its claimed 330bhp

Re: Hartge M5

Hartge H35-24, I might have some original literature from back then. Let me check!

After 25 years of understeer, a proper Quattro at last.

Re: Hartge M5

At least one of the 187 GB-spec cars has been modified.

Suggest you talk to Birds, the UK agent for Hartge, if you haven't already done this.

The minimal info I have seen in relation to this modified car suggests that all the work was to the cylinder head.

Regards

I would take those numbers with a grain of salt.....

If memory serves me right the performance numbers when tested was not as impressive as they should have been with 330 Hp.

I will take a look to see if I find some info.

Hi, new to the board, but have been watching for some time. The 330hp version was based on the e28 and E24 286hp engine, and we supplied 4 of these cars, engines built in UK, but all technology and componentry supplied by Hartge. Conversion was fully reworked head, inlet pipework, camshafts, slotted pulleys, camshafts, and engine management. The compression was 10.7:1 which was on the limit. We don't doubt the claimed HP, as the engines were mental at the top end. Last time we saw one was 3 years ago, had covered 135,909 miles, and had a substantial rebuild due to failed headgasket. We are also rebuilding the body on an H35-24 based on E30 M3, which I used to own. The best car I've owned so far.

Anyone wanting reprints of old editorial on these cars, respond with emial address and which car you are interested in. We should be able to find it!

Combustion chambers modified to give 10.7:1, Valves and valve seats modified to three angle configuration/narrow seat area, inlet and exhaust ports enlarged and matched to machined throttle bodies and exhaust manifolds. Camshafts were high lift and longer duration and as a consequence the cam carrier had to be machined for clearance. The camshaft pulleys are slotted to allow adjustement as the engine became a little peaky, and accurate timing set-up was a must. Effectively, all of the components above the head gasket line are modified. Additionally, Hartge supplied a revised ECU to take care of the fuelling and ignition requirements.

Regards, Kevin.

Re: Hartge M5

welcome abaord Kevin,

its great to see the owner(s) of one of the best tuning companies on here answering the questions.

I got one question, could the S38B36 engine benefit from those modifications and if so which ones? Have you eve modified the S38 from the E34?
