Jetting, timing, etc. Are you using E-85? Yes... from the pump BUT only summer grade EDIT If your on with your tune up then the timing is very close to what you have.. as for the fuel.. the carb needs 30% more fuel across the whole range Last edited by MR_P_BODY; 04/14/16 01:03 AM.

I sent it in to them and got back a perfect carb.. I ended up jetting it up 1 jet size.. idle was dead on.. that carb on my 405ci was super consistent... didnt vary more than a few thousands all day long

If you're not up for buying a new carb, and just want to put some gas in it to go racing, for that combo I'd start out with VP C-16. 68 Satellite, 383 with stock 906’s, 3550lbs, 11.18@123 Dealer for Comp Cams/Indy Heads

I didnt have the time to do it.. I was working lots of OT back then and it was worth my time to just send it in.. the best ET I got was a 8.96 and that was in the summer months.. I was doing license passes that day... I dont race in the fall months when its cool outside(thats when I change over to hunting mode)... in the spring I have to do my planting so no racing then either.. I'd post a pic of that carb but I think its too big

I did run 116 at first. Turned out it didn't need it. In fact I've run it on C-12 with no reduction in mph. However I can buy the Renegade 114 for the same price. Doug

fast68plymouth I Live Here F Joined: Jan 2003 Posts: 14,506 So. Burlington, Vt.	Every combo is different, so I figure its best to err on the conservative side until you know what it's going to need. Edit: I just Checked the VP site........ Looks like they have changed a few descriptions, and added some new fuels, and dropped a few others. Based on what I saw today, I'd probably try X16, or C14. C12 is rated for "up to" 15:1, so if I went that route I'd run a pretty conservative tune up to start with, and keep an eye on the plugs until you know it's working for you.

If you follow VP's advice and not leave it in the fuel system for extended periods, it's just a nuisance...... But if absolutely works. In a 468" SBC puller motor, making pretty good power(over 800hp), it was 35hp better than C16, back to back(after tuning)...... Both from sealed 5 gallon cans. 68 Satellite, 383 with stock 906’s, 3550lbs, 11.18@123 Dealer for Comp Cams/Indy Heads

Read below from VP website. C16™ Used in turbocharged engines, blown engines and nitrous applications with CRs up to 17:1. Recommended by the top nitrous oxide companies

[/quote i usually drane it after every outing at the track primarily because i street drive it and dont like to burn $$.otherwise ive left it in for a week but thats probably max.ive also seen 30hp better on the dyno over other fuels except for mark 5(115oct)which is also oxygenated and it was 15hp down.
