The Road to Drag Week 2014 - July 20

[Qikbbstang]

Jay think about using some "stock" panel type air filters. You can simply make a plastomeric or metal box w/ cut-outs where the filter panels simply plug in where ever they fit  on top and sides etc... Obviously you will not race with the street filters in place, the filters will require minimal flow since there will not be WOT in street trim.
For racing I presume you will simply use some sort of mesh screen to keep pebbles , bugs and low flying buzzards out and inside the scoop things are so tight. Here's one rectangular panel I'm can think of offhand - it's from a Gen1 Lightning:

Better tied behind my back than "free to do the devil's work" LOL!

I think that's what the Chevy guys are saying about you anyway...lol

Still curious how the remote thermostat gets enough heated water to open?

As usualy Jay, a clinic .  I'm thinkin' that other hand is probably typing, clearly not the devil's work.  I'm sure that sucker has a secretary to handle the busy work, and he wouldn't share anyway. 

Really looking forward to the finished product and following along on another trip thru drag week.

There is some circulation because I have a small hole, 1/8" I think, drilled in the thermostat.  I do that whenever I don't run the stock water bypass tube.  Of course, the cammer never had that bypass tube anyway.  So as the engine coolant heats up enough of the heated coolant must get to the thermostat in the housing, and start the process of opening it up.

Hey Jay. In bringing back up an older topic, I was doing some reading on a Ford DOHC engine Jon Kasse was working on.  I noticed in the photos that there is a "Hydraulic" chain tensioner.  Thought it would be of interest being from Ford.  Below is a link to the article as well as a picture showing the tensioner.  I know the one that was posted previously was out of a Nissan or Toyota

It'd sure be nice to have it all fit under the hood. I am not convinced you need that much plenum volume but if so the top could be made peaked in the middle (like a house roof) with the front throttle body leaned forward and the rear leaned back towards the cowl. Kinda weird but they only flow air.
 The underside of the hood can be used as an air cleaner lid, glue foam on top to take up any gap. Get filters with an ID that fits the air cleaner ring on the carb and you don't need a base either.

I'd like it all to fit under the hood too, Tom, but there's no way with that sheet metal intake, even if the plenum volume was reduced to zero.  You still have to have some room over the throttle bodies for the air to get in.  That was one thing that was nice about the Hilborn setup, it could have been made to fit under the hood for the street, and then add taller stacks to get fresh air at the track.

Chevy parts are uni parts they even work on garden tractors LOL.

TomP, the other issue with with oddly shaped inlets and undersized plenum volume is the stack up of compromises which altogether could represent a loss of 5-7% HP, 50-70 on a 1000 hp engine. Even with EFI, cylinder to cylinder balance is affected by both of those design considerations. The information Jay has posted has shown the value of top mount throttle bodies vs. front mount with his original plenum roof design.

Given Drag Week is also about going as quickly as possible five times in five days, we all have to make choices of esthetics vs. performance. Jay has had some of the best looking cars at the event year after year. I can't wait to see the final product in action at Tulsa this year. With right trans and chassis combination and optimized power Jay might be the first small tire N/A car in the 8's.

Whoa, now that would be sexy .

[Cyclone03]

A little bird, who I just made up, told me Jays SOHC is WAAAAYYYYYYY down on power this year.
Its struggling to make 600hp , Jay's running this year just for fun, be lucky to run 11.s. Cant even DREAM of 800hp much less 1000. LOL

Remember folks no ET or HP predictions till after DW day 1.

[jayb]

LOL!  No comment...

[cjetmech]

I'll bet it does make 600hp..................on a dyne at 12000ft
