Sidewinder intake VS modern, Edel, Pond, BT ?

[FUNFER2]

Is their any power differences between a bone stock original Sidewinder, Edelbrock, Blue Thunder and Pond intake ?

What is the power potential differences with the same,... ...porting & polishing technique's ?

[RodKnock]

Kevin, you should perform a search of Jay Brown over at the FE Forum. He has done a couple (or more) intake comparisons with almost every conceivable intake known to mankind. I'll try to find a link for you, if I get the time.

Kev, with the cubic inches you want to run coupled with a solid roller you need to stay away from dual plane intakes, especially the sidewinder. The Victor that you were talking about earlier is your best bet for feeding that beast. You don't want to mis-match components.

Kevin,

I ran a Sidewinder for several years until an unnamed person talked me into trading my Sidewinder for a new Blue Thunder Medium Riser. Huge loss of power and performance. Go with the Sidewinder if you have the opportunity.

Dave- I only have one photo of the side winder and did not notice it's a dual plane.

Clois- what were the differences ?

There's a side winder on ebay right now. I do have a new Victor Jr. that is sponsored but, I have not done much reading about the side winder so I'm curious about it.

[FWB]

here's some numbers on flow....note where the sidewinder ends up


BLUE THUNDER--- 210.925cfm
Police Interceptor 205.75
Edelbrock F427 202.075
Ford Sidewinder 196.162

Rpm Performer NOT 195.425
Next 2 are a couple Dual Plane Dual Quads Fords
Sorry I don't know exactly which ones I'm now much into 2x4
Ford C3AE-8425 191.01 Who would have thought this.
Ford Didn't get # Or Didn't Have one 209.435cfm

Single Planes
Holly Street 212.40cfm
Port O Sonic 210.175
Dove Med Riser Single 217.55cfm

and this is Jay Browns intake testing.........

I ran a Shelby Sidewinder, I think it's a vintage intake, and a Da Vinci 950 cfm Holley on my car for about a year and half. It ran smoothly and had tons of power. Went to Webers for the throttle response and eye appeal, and don't regret it. Webers aren't for everyone and the Shelby Sidewinder set up is really good in my opinion for the big block FE's.

I have the whole assembly, including linkage and Kirkham turkey pan if anyone wants it. Shoot me a PM if interested.

Then again Jay wasn't testing these with a 527" monster with BT CNC'd heads and a stout mechanical roller. Basically, all this info is totally worthless for Kev's engine. It's apples 'n oranges...

[Clois Harlan]

My experience is that the Sidewinder out performs all other stock intakes at the low end and especially for top end. I have ran a 2 x 4 set up, Edelbrock MR, and Blue Thunder MR. With the Sidewinder my engine pulled all the way through the power band like a freight train. Massive torque and in your face performance. I sold my sidewinder for $600.

This looks exactly like my old one:

except I closed the oil fill extension.

Clois

[FUNFER2]

That's correct Dave. Type & amount of porting and match up to the heads can be different from any builder.

FWB- I'll look over the link tonight. Thank you.

Clois- that's the one I mentioned for sale. There's 6 bidders and I'm sure it will go way past $600 What do they usually go for ?

[elmariachi]

Kevin, which carb are you planning to run and are you going to use this on the 428 in your signature?

I'm guesing the bigger and wilder the engine, the greater the difference, but it still may not be that much. Definitely, the sidewinder and BT dual planes look period correct, and they still can make good power.

I have a 477" FE, solid roller, 10.5:1, with a sidewinder and holley 950 HP, and it made close to 500 rwhp and 500 rwtq, like 490 or something like that.

[FUNFER2]

These is my thoughts on manifolds, for cobras.

Dual plane for owners that want nothing too radical of a engine, good even power through out the lower & middle rpm range. And, to be able to fit under the hood.

Single plane owners that have pretty stout big motors like mine, that already have high low rpm power, and is going to run higher rpm's and a lot of HP up top. Since I don't plan on making my cobra & motor a race car, road race or drag, I personally, think a overabundance of low rpm TQ, is just plane fun. I'm not so concerned with traction.

If I did race and was concerned about traction, I would build my cobra completely different.

IFS/IRS racing suspension, small block engine, light wheels, track tires, Richmond tranny, ect......

My cobra is for fun on the street, a bit of traveling, and occasional track time.
All out brute force, over the top performance and amazing sounds & feel.

(do you have the cam specs and dyno information on that Shelby FE) ?

Anthony- What are your cam specs & how do you like the solid on the street ?

[gsharapa]

CSX3170 didn't post the specs but he is on the forum so you could send him an email. It's a big motor with high compression so a bit of a different animal then what we are building. I talked to Keith and he said he has done a few Victors and milled the carb flange .500 to make sure everything clears. Said it would definately kill some of the low end tork and build more power up high and that's what I really want so I'm going that route now....

[FUNFER2]

I agree, and think we'll never miss the little torque loss in our cobras.
So, we see eye to eye.

about .680 lift, duration about 255-260 @ 0.050

Solids make more power than a similar spec hydraulic roller, from what I have seen, above 5000 rpm's.

There are drawbacks.

1. with an all aluminum engine, at ambient temperature about 70 F, the valve lash needs to be about 0.015 tighter to get the desired lash at operating temp. I have found it very difficult to start when the temp is below 50 F, sometimes impossible, as the lash is then too tight. Cast iron block is friendlier in cold weather.

2. With the stiffer springs, things can break easier, ie rocker arms.

3. Sometimes there is severe galling at the pushrod-rocker cup, but, from the various solid roller lifters I have seen, the ones with oiling to the roller bearings (crane, crower, jesel), the lifters also have an oil feed hole in their pusrod cup, and will likely oil feed the top of the pushrod if running hollow pushrods, and may eliminate that issue.

I'm still on the fence whether I should have gone hydraulic roller or not. My friend has a KC 482" FE hydraulic roller, dyno'd by KC with 600 HP at the flywheel. My engine is stronger by seat of the pants guaging. At another chasis dyno, not the one where I had my car done, his car dyno'd at about 400 rwhp and 400 rwtq. He runs an edelbrock performer rpm, and holley 950 or something like that.

[FUNFER2]

I now have a big,... problem with getting the motor done in time for the magazine shoot & interview's, at the Run & Gun, courteous of the salesman with Mahle Pistons. I ordered the slugs in first week in July and assumed,..... they were delivered to the engine builder, but when told me yesterday, he has not received them, I called Mahle, and my sales guy said he was sorry, that he did not put the order in !

Now it will take 3 weeks for them to custom make the 4.375 bore = 4.380 piston size. I did call two other company's, and they also would take about the same time to make.

As of today, if Mahle starts making them, by the time Dennis receives them and builds the motor, then delivered to me and time for me to install, I don't think I'll make the show.

Today- August 25
Pistons made in three weeks- Sept- 14
I would like 7 days to install & road test- Sept. 17
Run & Gun- Sept. 23-25

I don't see how I'll make it. Any ideas other than reducing the cid to 482 or 496, for shelf pistons ? Although, I would hate,.... to do this !

This screws up the entire project. I'm over being mad and now it really saddens me very much.

[Barry_R]

What is the desired compression distance? Pin size? Ring pack? I have something for another project on the shelf...

[Barry_R]

When I reference cam specs I am talking about duration @ .050 lift. The advertised duration numbers are nearly meaningless.
