im not quite ready for a 100 shot yet..but if my engine turns out ok i may do some tuning and try it out to see about breaking into the 12s ..anyways..i was reading this guys page who said on a dry system...the 42 jet in the bypass will work up to an 85 shot...but if you bump it up to a 100 - 125 shot ..to get more fuel..you may want to put a 55 jet in the bypass...has anyone ever heard of this or had experience with this?...just want to get some opinions

You need a SMALLER bypass jet in the T to get more pressure. Just so you know. I think james said that the 42 will work up to 120.Originally posted by 1DangerousV6:

Stick with the 42 in bypass and monitor your fuel pressure, if you need more lower the bypass jet.
John D. ran a smaller bypass jet for his 150 shot you can probably search and find exactly what size he used!Comment

I think it was a 28, but I don't remember for sure...
Stock fuel pump was only good to 120 shot.

Like he said, I'm running a walbro 255 in tank.
Going to that large of a shot requires more fuel you MAY max out the injectors and will definitely stress the pump.Comment

hmmm...cool....thanks guys...i was just wondering if anyone had heard of changing the bypass jet at all...as far as i know you just stick with the 42 ...which seems to be the opinion here...thanks!<b>12 SECOND DUAL STAGE DRY NITROUS POWERED 98 A4 V6 CAMARO<br /><a href=\"http://www.mysickcamaro.50megs.com\" target=\"_blank\">www.MySickCamaro.50megs.com</a><br />Best ET: 12.82@103<br />Best MPH: 104.7<br />Best 60\': 1.75 - Stock TC</b><br /> </font><blockquote><font size=\"1\" face=\"Verdana, Helvetica, sans-serif\">quote:</font><hr /><font size=\"2\" face=\"Verdana, Helvetica, sans-serif\">Originally posted by Shodown:<br /><strong>1DV6 runs 12\'s...enough said. </strong></font><hr /></blockquote><font size=\"2\" face=\"Verdana, Helvetica, sans-serif\">Comment

Why are you even thinking about upping the jets?
Truat me man, you/ your car is not ready.
I kept the same exact bypass jet from 85 to 120 dry shot.
When I went to the 120 dry shot with the stock fuel pump I seemed to need the kenne bell boost a pump
But, when i had the granatelli 255 lph the kenne bell would cause weird feedback and they did not play well with each other. I now run just the granatelli 255 lph pumpRace car - gone but not forgotten - 1997 firebird V6
