Just gotta love a mature lady with curves in all the right places... :devil:

Yes I do, JW, technically. It still has the factory casting number but that is the limit of the original design elements remaining.

StanJ has performed various mods to fit CPP heads; a full height divider (no gap), 3" spacer, 4150 base carb. The 4150 discharge flow pattern is cnc'd through the spacer all the way to the floor of the plenum, the runner entry into the two planes is hand blended from the plenum.

It remains a dual plane but it isn't a 2115 now.

Edit : Jan. 15, 2011

I have been asked by EZ, JW, and others what the results of all the 2115 mods was. The mods done, from the outset, was never intended to be used in the absence of the the rest of the engine combination. The 2115 we redesigned is not a stand alone piece. Thus, no before/after data exists.

My car, we refer to her as, Ruby, really is what has driven the engine design. Ruby is a 64 year old full figured four door fast back Olds with a WS6 T/A chassis makeover including Truck Arm rear suspension. A 4500 lb canyon carver and long distance cruiser.

The engine build concentrated on Tq from just above idle to 4000rpm . I spend 98 % of my driving time below 3000rpm, so, I have tried to make choices, create the pieces as necessary, resulting in total reliability, excellent driveability, big torque, and over 20mpg on 87 octane at cruise . The mpg remains to be seen when Ruby hits the road again.

The power looks like this ...
. RPM . . 32*Adv.87 . . .36*Adv.87 . . 36*Adv.93 . . 518ci/11.5cr

2500 . . . 272/573. . . . . 268/563. . . . 275/575. . . . . 280/589

3000 . . . 335/586 . . . . .336/584. . . . 336/587. . . . . 334/585

3500 . . . 395/590. . . . . 397/595. . . . 400/601. . . . . 398/598

4000 . . . 465/611. . . . . 464/609. . . . 468/614. . . . . 483/577

4500 . . . 485/565. . . . . 485/565. . . . 490/572. . . . . 486/567


Please note I have listed the octane used during the test .. all data is with the dual plane on my engine, other than the last column on the right, which is a single plane on different engine (4.38"x4.3", FT Hyd, .050 quench). My engine is 4.36"x4.15", cr of 10.3, quench at .035", solid roller.

My dual plane, as Stan has redesigned it, works very well. Its all in the combination.

Low RPM torque number look real nice, you can see that your already out of cam by 4500 rpms, but you have it designed for pulling

around a land yacht. I'm hoping to get 700 HP/700 TQ from my 10.5 compression 4.385" stroke 526 with the very well worked over

Iron 950 heads and AMC sized cam journals with a 264/258 duration hydrallic roller cam from MTS. I don't think the 700 HP will be a

problem, but the 700 TQ might be close. But I plan to use it in the 5000-6500 rpm range for 60 seconds at a time.

Always interesting to see others combinations for their intended purposes.

Dave, I'm jealous of you finding a Stealth for $100

Now I want one to play with.

$125 shipped. It's all Tom's fault;

http://cgi.ebay.com/ebaymotors/ws/eBayI ... K:MEWNX:IT

Found it by searching just stealth on ebay. Didn't show under 460.

The're less than $200 at Summit, btw. http://summitracing.com/search/?keyword ... alth&dds=1
Note, #8012 is regular heads, #8021 is CJ port.

I would have bought the 2x4 bluethunder setup that I showed in the other thread [for $550], but it was sold.

Plan is to make it fit the ports without adapters or goop [all welding]. I might look at using the base from a BD that I have, or maybe just use alum bar for the flanges. Or, sell it to a ford buddy and forget the sillyness.

Dave

anyone want an airgap performer?

Geez Tom, you're being kinda hard on the cam guy here. :crying:

Please correct me if memory fails here, Miles...but wasn't this thing still around 550 lbs/ft at 5000?

Yes...I guess I didn't word it right :jack: lol and shouldn't have posted it here :footinmouth:

It is for sale.....Ron

That's OK it's fine here.

I'd like to have, but hate to buy a new one to saw apart to see how it works. :screwy:

Tom
 
Oops. I'm a buyin' and Ron's a sellin'

Oh, come on Tom, since it's new, you will not get dirty while you cut it up.

Miles,

Impressive torque there. Did you flow the head with your improved 2115 bolted on? Iirc, stock they flow something like 26x on long and 27x on short. A helluva choke even on a decent iron.

I must say that I'm curious as to how badly it choked the potter heads.

Dave

Thanks, Dave, for the flowers. I tried to do all the testing and data gathering I could but that is one worthwhile bit 'circumstances' prevented .

ExtrudeHone would be my choice as a follow on to the work we have done but they're shonuf proud of their work ...
