I have had to convert my circut car back into a drag car for Warwick as the new car is still not ready . I had a 2443 cc engine laying here that I used @ Portland this year to run a 7.28 sec pass and have now installed it into my '75 L bug . I was on the dyno last Saturday and with 175 HP of nitrous and almost 15:1 comp , the engine made 296 HP at the wheels before I melted a head . I have Welded the Autocraft head , machined it , rebuilt the engine and lowered the comp to 12.1:1 . I was on the dyno yesterday and the end result was 306 HP with a 200 shot at the wheels . This is almost 400 HP from the engine and I am now set for Warwick with a new spare transmission and 4 full nitrous bottles , ROD.

Dave , thanks for posting the dyno sheets . The first sheet was from the Saturday session and you can see that the engine made 198 hp with a 42mm venturie , as raced @ Portland this year , and now it made 206 hp with a 45.25mm venturie . Unfortunatly I have now had to loweer the comp. to 12.1 and now I have dropped to 185 hp @ the wheels .
The next sheet was also the Saturday session and it made 296 hp and then melted the head . I am still not quite sure why it melted as the engine was not lean , so I think I am @ the limit of what the VW engine can handle . I am still not that confident that the fuel was up to spec as well .
I have now lowered the comp and ended up with 306 rear wheel hp with a fresh drum of fuel and I am happy with the tune up . I am not confident that the transmission will last and the clutch will do too much more work so I have some spares with me . I am getting 121 rear wheel hp from a 200 shot of gas and this will be my limit unless I can source some larger jets . I should not have any axle tramp issues as I have changed the BF goodridge semi slick tyres to a Mickey Thompson drag slick , and have installed a new cro-moly kafer bar , see you on the north side of the border , ROD.

Hope you haven't worn Jason's dyno out............I need to get the Cooper Porsche down there soon. I want to find out how good a job you did on those 356 heads, and to tune the Webers & ignition.

Enjoy Warwick, Rod, and go quick!👍👍
I'd rather wear a Beetle out by racing it than by polishing it!

Nice vid Lisa and Pete.....I wish you guys got some more sales out of the previous years DVD's to produce one again this year (I can undersatnd why not though due to the time involved!). My 3 year old son Kai has pretty much got the previous ones on rotation through our DVD player non stop!

Well done on giving it everything Rod - a great time and certainly entertaining!
