Before I come down,  I'd like to buy a larger set of paddles, but I don't know which ones to buy.  I'd like a 30" paddle to insure that when i'm at full bump, my chassis isn't slapping the ground. I could go with a set of 28's too. Any input from you more experienced duners would be greatly appreciated.

good for you and impressive on there part.  that is so damn funny as well  LMAO    your right, forums have fallen off because of social media groups like facebook. now i looks at a few of them from time to time and no real good info or flat wrong info. i always pipe up and state they need to search a forum dedicated to that if they want real info. rarely do many but i think there younger kids.

 LMAO LMAO LMAO LMAO LMAO LMAO LMAO LMAO LMAO LMAO LMAO LMAO  For the last many months I've been frequenting the FAST EFI forum. Like many forums participation has fallen off severely and the truly helpful and knowledgeable members have gotten tired of answering the same questions over and over.  ANYWAY,there is/was a member there that thought the forum had become his own little kingdom and his advise/answers were NOT to be questioned. know what that sounded like to me. :m It sounded like a effer that needed taught a few manners.  Ya,I took it upon myself to do the deed. ;D ;D  He just kept getting more and more unhinged to say the least and was outright attacking pretty much everyone. All the CPG/FAST/TCI/etc. people have been absent the last year and this dick head knew he could just do any damn thing he pleased without any consequences. So he thought.  rofl rofl I called FAST and asked if there was anyone actually in charge of the forums. The guy asked why I asked and I politely explained. He asked if I could stay on hold a few minutes and sure I waited. Apparently he went to the forum and quickly came back to me. He thanked me for making them aware of the situation. Call was over and I just assumed that was the end of it. NOPE!!!! LMAO LMAO LMAO LMAO LMAO they pulled a Hillary on him and acid washed/bleachbitted the hell out of his account. I've never seen such scorched earth purging of a member of any forum anywhere ever. There is litterally no trace of his ass on ANY of the CPG forums now. Every last shred of him ever having been on the CPG forums is gone. WOW!!!! they didn't eff around one little bit. :m :m

I just checked the calendar... I looked at Aug, and not Sept...

I'll be there 17 thru 21.
Motor and Drivetrain / Valve Lash and RPM
« Last post by fabr on June 19, 2019, 07:24:14 PM »
I found this short info article damn interesting. Note the bold red number. WOW!!! DAMN!!!! I had no idea anything ran that much lift. Inferring from the article that motor must run close to zero lash. This old nascar engine had almost no lash either.  I'm having a custom cam ground for it to make it a bit more suitable to fast duning/desert running. I'll know tomorrow what the lash spec will be for it. Got me really curious. Anyway,here's the article.

Competition valve spring design and its relationship to lash.


A chief misunderstanding of valve lash is how it correlates to rocker ratio. When you compare a 1.5:1 rocker functioning with lash of 0.015in to a 2.0:1 rocker ratio also with 0.015in lash, they are not the same. Given a common lash of 0.015in., the 2.0:1 rocker begins to move the lifter at 0.0075in compared to the 1.5:1 rocker where valve movement begins at 0.010in. Also, the speed of the ramp is changing. A camshaft designed for 0.015in lash but mistakenly adjusted it to 0.025in, would probably increase the speed of the moving parts by 20 times.

As engine speed increases, the valve train components continue to hit harder and harder, which causes them to distort more and more. They all bend: the rocker arms bend, the pushrods bend, the fork on the lifter bends, the camshaft winds up. As a result, valve train components are designed to operate at the engine’s highest rpm—this is the point where they cannot sustain further abuse.

Another misnomer is the relationship between the crankshaft and the camshaft. Though connected by a chain, the camshaft responds only to the clock on the wall. As engine speeds increase, mechanical activity happens faster in relation to the clock. So, this is why an engine spinning at 8,000rpm can operate with valve lift of 1.200in, whereas an engine turning 10,000rpm is likely limited to around 1 inch of lift. This is because there is only a certain amount of time available to move the valve, and that’s a lot faster in relation to the crank.

Joe Hornick has designed successful racing camshafts and valve train for both 903ci Pro Mod engines and NHRA Pro Stock engines. One of his most successful Pro Mod engines operated with 1.440in lift compared to a front-running Pro Stock engine with 1.190in lift. Because the Pro Stock engine revs so much higher, it operates with less lift—although valve speed remains the same.

Competition valve spring designers are obliged to move the valve train at its maximum velocity, and the best way to accomplish this is to integrate the spring’s natural frequency with the correct spring rate. Extreme spring pressure provokes excessive deflection in the valve train and when combined with a disregard of the spring’s natural frequency, the valve train doesn’t react well.

carl....that did suck ! i believe the rec reg did it but i dont know for sure. i know you've got a damn busy 4 weeks ahead of ya but remember to yank that out and mail it to have it checked by bazzaz atleat. worst case they throw it away, best case they figure it out.

i just pulled mine out of the th'er last thurs evening.  i will be pulling the motor next week i believe. if enemy get that head ready then i will be swapping to a better head. i WILL BE setting cam timing with a degree ring as the head and block were decked .007 or .010 combined. i cannot find the paper work that i did save with that info. apperantly using the e bar method doesnt really work once the head and block have been decked. enemy figure out he was almost 1 tooth off checking with a degree ring.

I run a ga scirocco single pass. I upgraded fan (still didn’t shell out spall $$) but cooling is no problem even with the turbo now. I run separate oil cooler in front of rad. And on e85 too.

Really wish elec problem didn’t cut my trip short by a day or so. It was just getting into the fun boost area!
