Advice on FDR with Vampire Bloodline
 

Hey guys,
I am after a little help if possible.

I am running an Xray T3 2011 with and FDR of 7.60 (84 Spur/21 Pinion) at present with a Speed Passion GT2.0 and a speed passion V3 Comp 13.5 boosted.

I have just purchased a Vampire Bloodline Type AB+ 13.5 and have been advised I need to reduce the FDR due to the increase in power from the new motor.

Does anyone have any advice, I run at a relativley small indoor Touring car club

Thanks in advance.

I ran something similar for a while but found on small tracks the boost could be a hindrance so now I run 5.5 - 6 FDR with no boost but can add it if the track layout is fast

Thanks

I run a 23 with a 84 spur with a lrp motor boosted
