2.5" Hard pipe upgrade removes fords 2.0" restrictive boost pipes. We saw gains of 11.8 bhp & 9 lb/ft torque increase's over the standard ford pipes, these gains were achieved by simply bolting on the big AS 2.5" Boost pipe kit!
Fitted to Marc Marsden's 694.8bhp Jamsport built, AS/Airtec & Revo software RS Mk2 '694.8 BHP ROLLING ROAD TESTED!!' AIRTEC Stage 2 Intercooler & the market leading 2.5" big boost pipe kit makes it a must upgrade for your 400+BHP Focus RS (Rolling road recorded unofficial 733 bhp/650 lbft, but moved on rollers @ end of run)
All Pipe's have swayed ends to stop the pipes blowing off on BIG BHP Focus RS's & Finished in Pro-Series satin Black
Why a Stage2 ? With Focus RS tuning being pushed to new levels with 400+ packages becoming the norm, we knew a bigger better flowing intercooler would be a great addition to these new exciting power packages.
The Problem we had is that the original design Airtec Intercooler is so good! and had been proven on a 500+ bhp Focus, so we went about making something good 'even better' We knew our bar 'n' plate core was great @ displacing heat and very close to unbeatable on rolling road testing, so the 60mm core was upgraded to a 65mm unit. Then we looked @ flow, this would make or break the stage 2, making the Air flow as easily as possible and making sure there wasn't any sharpe corners to slow the Air down. Check out the Un-finished silver Intercooler, this clearly shows the efforts & design that went into the stage2 end tanks, simply stunning!
Test results Carried out on Jamsports demo car.
