Badass, what transmission does it use?

*edit - read the page its a liberty clutchless 5 speed.

 

Not to be a dork, but are there more than 1 2.09 litre Honda rear engined dragsters running in NHRA? If so how many?

lol i was thinking the same thing...curious to see how much power it actually makes though

also in the link it says it's a "serpent's" head. did endyn just recently do the work?

 

Didn't I see this as Larry meaux's work on another site?He's from that area and that name is on the NHRA Certificate.I wonder if Larry Widmer tuned up his head or it's another deal and I'm mistaken?Look's fabulous either way though.

 

This head was fabricated and CNC ported entirely in our shop. We are using valves that are 2mm smaller on the intake, and 1mm smaller on the exhaust, and out-flowing the old head by as much as 35cfm. At 42cc's, the chamber volume is also down 9cc's from the previous head. We've also made the pistons for the engine. I'll have the rods finished Monday. Block-work is also complete.
Our goal is to increase mid-range power without sacrificing any on top. Best estimate on crank power before (from Larry Meaux) was 390HP.

How many other Honda's run in the real NHRA isn't relevant.

At least the "darkside" is willing to show and discuss what they're working on......

What the EVO guy's that hold the class record? Shame on them. Endyne says he will have rods on Monday. How do you set a record with no rods in the motor. Playstation?
Reread the first post it is "for" not it "is" as Bill Clinton would say. Hopes to be, would be another term.
I hope it represents, when will the car run?

Cheetah said this is the LATEST head/motor for this guy from Endyn. He broke the record with the old set up (using Playstation2). Now he is stepping up to PS3

 

Who did?

Examine the picture (CHEETAH 1st post) the intake valve size look std ore a bit oversized, is it the same head endyn explain about??

The exhaust valves are 1mm smaller than a stock S2K head uses. The old head had 38mm intake valves, making ours 36mm (stock S2k). We also made the beryllium -copper valve seats in-house from bar stock. The valves we're using are titanium with Chevy IRL valve springs.
I should have the small-ends of the rods machined (to length) Monday, so the engine will go together as quickly as possible. Final compression is 16.2-1 with .065" piston to valve on both sides....so clearance-wise the combination's very safe.

For the last 6-months we've been working on a Minibushi engine to replace the S2K in the dragster. Right now it looks to be capable of out-performing the Honda handily....and they (Mitsu) are even footing the bill for it.

 

Now it is clear about the valve sizes,
I haven't yet understand what head used when this f dragster made the record?
the old one with big valves? this was also endyn prepared head?
If yes, with the new head we have to wait improvements.

 

so some one needs to fix this post it needs to say LarryMeaux's head has the nhra F/D record and that ENDYN hopes to set the record right..... and are they selling to old head if so have them give me a call.....

 

head is coming along ... sick numbers

 

If you are interested in the old head, call me. I'm more than sure I can arrange a sale on it.

 

cool ****

 

Is this supposed to be the comp elim F/D record? Because NHRA is still showing an 8.08 at 155 record for this class.

 

Larry thanks for you help i called but you were on another line....
