We have been supercharging 11-1 compression ratio engines for years, they work well. :voldar02:
Also, I dont agree they are a time bomb, if it has the right amount of fuel in it, the right amount of timing in it and the customer uses the correct fuel, it will live, the same as every high performance engine. You just got to get it right.
If you follow this link for the build up of a Super Charged, Super Pursuit 315: http://www.c31.org.au
Then search: Oz Garage, then click on the 24th of May episode.

Hi Matt,
Our position on this topic is simple. We see our 260 engines and 290 engines making a solid 400rwkw for their 10psi boost investment. To see a 315 make 350 with 10psi on your TV episode CONVINCED me not to do this. There is an obvious inefficiency here, which like it or not increases risk of engine unreliability
The higher compression in the 315 is more lended to NA modification rather than forced induction. The reality of this for me is, as a business owner is that yes, we could relent and sell these kits to higher comp Boss owners, and yes with careful tuning there may be some power, albeit not as much with a "better" suited engine, and again, with extra risk.
However,
I do believe that as a result of this, we do run a higher risk of hurting an engine, and if by some chance that on hurting the engine the blower ingests some material, not only do you have the cost of an engine to contend with, but also blower repair or replacement, and since we are talking high end Billet compressors here, we are talking $$$$.
What I say on these forums may not always make sense to people, but we make these claims for a reason Matt, end of the day, the customer is the most important person, without them I would be working at the post office licking stamps. Sales are nice, but having a largely happy customer base is more critical.
We cannot stop people from taking one of our kits off a 260 and fitting it to a 302/315, all we can do is educate. As i say, extra sales are nice, but we will be keeping our policy in check for the ultimate benefit of our client base.
Hope you and the family are well,
Chris
