I've got 24lb injs, 110L in tank with the Nos 0015 upgrade kit including its in-line aux fuel pump. Currently I'm using jet #45 in the tee and #67 jet in the fan spray nozzle. Which jets should I use to make the most of this system or is this as good as I can get. I've read some old posts that suggest it's possible to get up to 175hp but exactly which jets do I buy for this set-up. Currently I only drop about 5-6 tenths and gain about 8mph. On engine I've gone [email protected] and this past weekend I managed [email protected] on nitrous. Need help fast got a big weekend coming.
