Doesn't seem to be the case with this Pepsi can... filled with water, top left open for 'the easy way out', and it still split the can... Clearly a safe would hold out a little longer, but in the end, the same thing will happen... as it will with your engine. Not specifically picking on you... it just seemed like an easy target

I had EXACTLY the same symptoms with my '95 LT1. As it began warming up, one channel of the Optispark would start going erratic, and kill the engine. Let it cool down for a few minutes and start the process all over.

If the rumor is true, Dave missed best of show by ONE vote!

Why does this sound backward? I sure wish my customers would bring ME the tools I need

That is the tool I own/use. Its a great fit for the manifold side but I prefer it were a little tighter fit for the rail side. I havent had a leak yet... but I'm not interested in making the bet that I never will. On the shopping list is a non-standard reamer for rail machining.

I'm sure mine doesn't qualify as 'the best' but it was fun seeing how inexpensively one could be put together. I built one for ~$2600 around 2002... adjust for cost-of-living... http://forums.hybridz.org/showthread.php?t=118146

I'll second that.

At 4ms dwell, sequentially triggered coils will only charge individually to 5000rpm. Beyond that, two channels will charge simultaneously. To complicate matters, it won't 'double' as the initial charge current is far greater than at the end of the charge. Moving on... at 5ms, 4000rpm is max. before charging two channels. LS1 coils are going to want around 5ms charge time at torque peak. Yup, but only double below 5000 at 4ms, double below 4000 at 5ms. I'm not 'Haltech savvy' so I could easily be mistaken, but this doesn't sound right to me. If that parameter is referencing the mechanical lead before number one TDC, then 36 degrees isn't enough. ECU can't 'go back in time'... there must be as much mechanical lead as the max. timing you run. I run more than 36. Tommy, if you are having doubt's about your mechanical lead, this implies that you haven't verified that timing is 'as requested'. This will get you into a heap of trouble. You MUST verify ignition timing... after that verify it again ... then verify that cyl. 6 is firing at the same deg. as number one. P.S. Where is your dealer? Is he not helping you sort this?

First, admittedly this is a bit of conflict in interest, so I'll do my best to keep to the facts. That said, If anyone feels this post inappropriate I'll remove it. Second, and mostly moot... my specialty has been primarily L-series. I use the Nissan CAS exclusively in those applications and have tested to 7500 rpm, with no trigger errors, period. However, as I mentioned previously, I'm opting to read only the 6 slot row. Third, I've only recently been submersed into the RB installations so specific personal experience is limited. For this reason, I contacted Steve Taylor, owner of Wolf3D, to get a broader scope. In short, Wolf's plug-N-play's use both rows, counting how many slots are within each of the 6, to determine where cylinder one is. The implication is that the actual timing is a function of the 6 slot row. I couldn't say if the strategy (including the unspoken strategy) is any different than AEM. However, I have his assurance that Wolf has proven to be consistently reliable to 10,000 RPM, with a properly functioning, untouched CAS. Fourth, 'reading between the lines', he defended AEM to some degree, with the statement that these CAS sensors and their wiring are getting old and the *occasional* issue should not be a surprise.

Yo, can you get 335/20/13's? TIA,

"Turbobluestreak" was kind enough to produce some CFD work on this manifold (Thanks!). One of the goals of the design was to reduce the turbulence immediately after the TB. Looks like success... Another high priority was equal cylinder distribution. *Almost* accomplished that. The generous short side radius was an effort to promote this. Seems I still ended up with a small stagnant area in the corner. Also, the unexpected detachment on the outboard perimeter wall seems to cause enough of a low pressure to effect cylinder's 3 & 4 to some degree. The consequences of the reversion in the low pressure zone I suspect to be pretty negligible... the least of my concern's anyhow..... I found this to be pretty enlightening. However, I must add that static testing like this is a serious over-simplification, completely disregarding Hemholtz, acoustics, valve events, etc... Interesting nonetheless. In response to this, I've made some plenum revisions and TBS has offered to test them...

Blinkers? You don't need no stinking blinkers... hand signals are perfectly legal

Great! Anybody else?

Monzter, I had something similar in mind for manifold number two... with the exception of being two-piece, top and bottom halves. I like your idea much better. Sadly, I'm adjusting the shape of the plenum such that it will no longer work as a one-piece. Keep in mind that we are somewhat past the prototyping phase, as one has already been completed and running. As for .063, I really feel this is a poor choice for boosted app's. I've personally seen ballooned .120" manifolds. I know of BWM folks, running manifold's of similar shape, that have had trouble with .120", hence the internal stiffeners. I'd be happy to have someone prove me wrong. All I'm saying is, if I were building one with boost in mind, it would not be less than .120" and there would be internal reinforcement.

It would have been marketing genius if he would have used a 'woman's knee'

I'm not too sure about you guy's anymore... I wasn't going to stare long enough at a 'mans arse' to figure out that it wasn't. Yup.... still *shaking head*

Look again Raff... that's no knee! "uhhh... wanna trade butt's?... mines gotta crack in it...."

Yes... http://forums.hybridz.org/showthread.php?p=776495#post776495

Picture doesn't come in for me. That's a fact! Even at .120", I think internal stiffeners, for big boost applications, would be desirable. Just a few pieces of 1/2" round stock strategically welded in vertically, would probably suffice.

Sure are... When I use the Nissan CAS, I don't bother with the 360 slot row... only the 6 slot row (adding a sync hole for number 1). They've been flawless.

Best compliment I've had all week
