Unravelling the mysteries of the G H-C set-up

Reponse from Garry Kemp racing - many thanks to Garry.

"John [Hazzard] bought most of it from George Howard-Chappel at Lotus GT1 racing in the mid / late 90's.

I am surprised at the power output though; engines I've done to a similar spec would make 350-380hp. However you are probably being a bit conservative with the boost; Lotus ran 1.2 bar boost for races and 1.5 for qualifying.

Dermot will I am sure be interested in the ECM - the fact it can run with a 3 bar map sensor; but I recall John having a problem with the race ECM in his car; maybe he got it fixed?

If your injectors are Carlton ones they will have black bodies rather than the grey stock ones. That said Lotus must only have used the Carlton injector because they had them at hand - they are Rochester injectors and have an awful spray pattern. You will find some more power and improved drivability getting rid of those."


Garry can build a blueprinted & balanced race engine with a 2.6 litre Honda crank, rods etc but little change from 10K.. aarrggh. However std set-up ok to run up to 380bhp so will settle for 350-380 for now. When finances are ready then I'd love to see what a Garry Kemp engine felt like..

Next stop may be a decent boost controller to phase in the boost as apparently she's a bit lively now.. Kev @ Falkland recommends the HKS unit. Target wil be 1.2 bar and hopefully the low boost solenoid will still work for wet until I can get a better controller. May look to get the gasket uprated asap..
