£209.00 inc. VAT

If you’re pushing high boost pressures with maximum timing advance it’s possible to lift the head on high powered BP engines, even with ARP Studs in standard size.

After extensive testing we’ve found that this gasket provides that little extra protection from this situation and is worth doing if you’re intending on pushing past 400bhp with a smaller frame turbocharger that requires more timing / cylinder pressure to make the numbers.

The gasket comes with a composite material for the oil and water surfaces and a fire ring gasket for each bore. The fire rings are precisely 84.5mm in diameter, as such the largest bore you can reliably fit these on is 84mm. 84.5mm might be possible with absolute precision.

The thickness is 1.4mm / 55 thou which does drop the compression ratio by 0.2, machine the head and deck surfaces to bring this back or use higher compression pistons as required. Tested on 9.3:1 static compression ratio engines.

Products must be installed by an independent experienced professional mechanic and the suspected defect must be present at the outset. The warranty does not cover damage caused by incorrect installation, failure to comply with the maintenance requirements of the vehicle, processing or otherwise changing the product, ordinary wear and tear, or any other external influences.

Making a warranty claim

Proof of purchase receipt showing the date of purchase, proof of mileage at installation, proof of current mileage and invoice of the work undertaken by an independent experienced professional mechanic must be supplied along with the returned products for a warranty claim to be considered. If your vehicle needs to be used whilst your warranty claim is considered replacement parts from the same manufacturer should be purchased through BOFI Racing. In the event of a successful warranty claim, we will refund the card that was originally used to purchase the replacement parts, in full or in part depending on the nature of the claim. BOFI Racing reserves the right to make full or partial compensation at its sole discretion depending on the condition and mileage use of the returned suspect parts. For example, if you have used the part for several thousand miles before a defect is noticed, only partial compensation may be offered.
