Pepper runs a new BEST.
Re: Pepper runs a new BEST. John,
How is the idle of the C2 cam compared to the C1? The reason I ask is that I too, am also going to go with some of those new XE-R lobes on my new cam. If it idles the same or better than the C1, I might consider going bigger than my original plan. Talk to me amigo.

Re: Pepper runs a new BEST. Awesome runs. Who'd of thunk it just a few years ago?
Mind answering a few questions?
Do you know what the car weighed?
You said you blew up the motor...is it back together with a stock rebuild, or did you get another stock shortblock? If you rebuilt it, did you do upgrade anything...such as pistons, crank, etc.
Thanks, and congrats again.

Re: Pepper runs a new BEST. Those are some UNBELIEVABLE ET's John! I bet a 1.38 makes for a nice ride. I'll definitely be looking for that video when it makes it up. <img src="gr_eek2.gif" border="0"> BTW, having a RT that is close to matching your 60' is a bad thing. <img src="gr_images/icons/wink.gif" border="0"> <img src="gr_tounge.gif" border="0">
Congrats on the new bests.

Re: Pepper runs a new BEST. LOL, you guys!
The RT is like that for a reason. I wait for the lights to come on and then recheck my launch RPM's as the other fella in the other lane takes off. Since I am not racing any one per say, and just looking for "a number" it is really a non-issue with me. I want to make sure I am at the RPM that I want to be at.
And once he is gone, I dont have to worry about his loud *** trailor car drowning out out my cars sounds. I need to hear what all is going on. Giving the other fella a second or so to get going and then after I have got my house in order. (RPM's where I want them and everything is looking good) I hit it.
I dont want to be "all up on the converter" while I am sitting there waiting for the lights to start dropping. That serves no purpose other than heating up the tranny needlessly. So I wait until the third yellow comes on, pop the revs up to my target RPM and then if everything is hunky dory I stab it and hang on.
I try and do everything the same one every run. I only change the one thing that I am experimenting with at that particular time.
So far that system is working pretty good. You guys on your bracket racing nights take care of that R/T. Me? I am just working on E.T. R/T is a non-issue.

Re: Pepper runs a new BEST. What's really incredible is picking up .06 in 60ft times and over 2mph in a car that's already doing 1.44's and running 122mph without doing anything to it!!! That's what has got me dumfounded. <img src="images/icons/confused.gif" border="0">

Re: Pepper runs a new BEST. He went back to his old converter that has worked so well for him. Before that he made some headwork changes and went to a slightly bigger cam but was majorly hindered by a too loose converter.
I'm absolutely dumbfounded by (and jealous of) that 60 ft time! <img src="gr_eek2.gif" border="0">

Re: Pepper runs a new BEST. Steve I was not talking about a before and after I was talking about the same day. A 1.44 to a 1.38 60ft on a car that's already hooked up is hard to do. <img src="images/icons/confused.gif" border="0">
Re: Pepper runs a new BEST. John also noted a good drop in temp during the hour his car rested. That could explain the mph difference. As for the 60', a whole lot rubber was probably laid down in that hour as well which made a better launching surface + the additional power from the temp drop. My car over the course of a night has gained 2mph and .05 in 60', but I'm not going to compare my car to his because Pepper is on a whole nother level. <img src="gr_grin.gif" border="0"> <img src="graemlins/gr_hail.gif" border="0" alt="[hail]" />
BTW John, are you still using the 10 bolt?

Re: Pepper runs a new BEST. Top Fuel I thought about the track but John said the track was in great shape and I also know that Pro Stock and Pro Mod cars had been running there since Wednesday so I'm sure there was plenty of good rubber on the starting line. At six in the evening at HRP the air is already cool and dry. Temp don't change density altitude as much as humidity and pressure does.
It's amazing that John can get get his car to better it's 60ft times .06 when it's doing a 1.44 already. Heck he picked up .22sec in the 1/4 mile ET and all he did was remove the muffler and adjust the tire pressure.
Amazing just amazing.

Re: Pepper runs a new BEST. Good runs, John! Awesome to see what a 'lil old 346cid is capable of!!!
I should be back together in 6-7 weeks, if my estimates are right, and things come together as I hope they will. The good weather will be gone by then, but I have some pretty high goals for the car once it comes back together...
Anyway, congrats!!!!!

I'd have to disagree slightly here. If you play with any DA calculator, you'll see that of the three main factors(ambient air temp, humidity, and baro. pressure), humidity plays the smallest role. 10º drops in temp. are normal out at HRP on any given night and this will send the DA dropping quickly. On the other hand, increases in dewpoint temp. tend to rise come nightfall, hence the humidity will come up and "moisten" the air a bit. Just some weather phenomena I've noticed...
