Well its time to try some diffrent things with the grp so here goes

This weekend i will try it with a 14t clutch bell ali shoes, hard xray clutch springs  and a 7mm venturi.

In the winter series I originally ran a 15T but found it was only really getting into its stride at the end of the straights at the front and back of the track.  14T made it more useable, for sure.  I imagine the GRP is smooth power delivery so shouldn't be an issue? 7mm venturi should help.  I stuck with an 8mm on the Go .28 6 port but it drinks far more than the GRP motor by all accounts.

If you find the clutch isn't up to the job let me know - my 4 shoe runs very light springs (0.9mm) so it doesn't slip and wear the shoes out too quickly.  No problem with bottom end.

Looking forward to seeing the GRP in action - it's on my shopping list for next week, along with the Speed

I have timmed the 8mm venturi and it was returning 8 and a half mins runtime. The GRP compared to my RB is smoother and so nice through the whole powerband I ran a 13t clutch bell last round and it was super fast. However with a dirt track you will find you spin out trying to lay down the power on the dust coming out the corner if you accelerate too fast  "gilty"  so hence the change to the 14t to compensate my heavy on the gas driving style. Pop over and you welcome to have a look at the setup etc. You cant go far wrong with a GRP they are a real eye opener.

Well all i can say is this engine is fantastic with the changes it was just shy of 11 and a half mins run time  the 14t clutch bell tammed it a little and made it eaven easier to drive. The clutch setup was spot on and it seemed to have alot more power.
