A Klarius exhaust and CAT system has added 25hp to amateur racer Martin Gadsby’s BMW Compact Cup car.
As a relative newbie to the sport, Martin is now in his third season having rebuilt his original car ‘a couple of times’ having visited the barrier in treacherous conditions.
Working his way up the field the next rebuild came at the behest of creating a more competitive machine.
“The rules are pretty clear for the Compact Cup and they restrict what you can do to help keep costs affordable for privately funded racers with minimal sponsorship.
“As I’ve improved though I could see where the leading cars were making time, especially on the straights, so the search started for upgrades that gave the best return for the investment.
“Klarius produces an ‘official’ approved race exhausts system so I knew I was on safe ground with regards the rules, but I wanted to be sure the system would deliver results when other engine mods are limited.
“I actually spoke to the head of research and development at Klarius, Doug Bentley, who has a track prepared E36 M3 which spends a fair bit of time at the Nürburgring, so I felt I could trust his opinion.”
Doug Bentley added: “We usually see around ten per cent improvement when changing from the standard road system to the Klarius system on a Compact Cup car, however, when the intake airflow and engine tune are also matched and balanced to the backpressure of the new system, you can see better results.
“That said, 25hp has to be the best result we’ve seen yet.”
Martin’s car is a 1998 3 door, BMW 318ti Compact with the 1900cc, 4-cylinder, 16 valve M44 engine.
The Klarius exhaust system with or without 200 cell high-flow CAT is available directly from Klarius and other race parts suppliers.
