HOW TO SELECT A PERFORMANCE CAMSHAFT

When selecting a performance camshaft, consider the use for which the vehicle will be required.

We all know the claims: 20 BHP extra. This sounds great – but think! These automotive manufacturers can’t be that silly to disregard

20 BHP by changing a camshaft.

Ask yourself! Where is this 20 BHP? Probably not where you will ever use it at 7500 rpm. Well, probably we will use it, occasionally;

it would be nice to have in reserve.

Hold on! In this world there is no such thing as a “free meal”. What’s the possible trade-off of this 20 BHP? It could be a loss of 10

BHP at 2500 rpm. This means, each time you accelerate through 2500 rpm, you could lose 10 BHP. This to me, doesn’t sound too

good.

SOLUTION

Be conservative! Don’t over-cam your engine. Choose your cam for the correct application. Consider! Fit a milder cam and increase

your power by 10 BHP at 3500 rpm.

Remember! You get this 10 HP every time you accelerate through 3500 rpm. Multiply this by 10 HP each time you drive through 3500

rpm then deduct the times you reach 7500 rpm.

I’m sure you will find more horsepower on the 3500 rpm side than the 7500 rpm calculation.

 

MATERIAL TYPE (PERFORMANCE CAMSHAFTS)

You will note that we have a material description at the end of the camshaft specification. This informs of the following:

Billet

This means that the camshaft has been turned from a round steel bar and will normally be nitrided after grinding.

We use this method for low volume production and, due to the work involved, they are always more expensive than cast blanks

Blank

Unless specified, the camshaft is made from a chilled iron casting. This is the best material for camshafts, as it has far superior wear

characteristics than any other material.

REPRO

A regrind on an existing camshaft, only suitable for mild grinds on existing chilled iron camshafts. If you regrind case hardened steel camshafts you will remove the case hardening. We only regrind chilled iron cams, but prefer to supply new units
