Any single plane stock bottom end guys in here ?? sup vic, Mast etc..

If so, hows the tq curve treating ya ??

Peak tq RPM ??

Effective gearing for the new found rpm's ??

Basically looking for feedback on this setup, I truly feel the ptv will limit the breathing of this combo but wanted to see if anyone has had success with it.


Thanks...............or any quick single plane manual cars out there in general ??

Wow......so there are no sbe single plane manual cars running around ??

Thanks......

I will be shortly... but not right now. bklue99fbody is and so are a few other guys.

like said, im running a vic jr and have no regrets other than wishing i had a super vic. car made 500/470 n/a with a fast 90/90 and 522/465 with the vic jr so not much tq was lost, i dont have a dyno sheet to look at to tell you what rpm that was made but i didnt notice much difference in tq driving/racing the car but definatly noticed the power up top.

im a nitrous car and dont really care about n/a numbers and very very rarely even make a n/a pass. i run 3.90 gears for the nitrous which provides more than enough tq for it to leave as hard as a 1.32 60' and trap 148mph. when i do run n/a i leave around 6k+.

Thanks for the info.......

What cube or you ?? sbe ??

How much did you raise your shift rpm when switched to the single plane ??

Did you do a cam swap to take advantage of the single plane ??

Did you pick up et by raising your shift rpm ??

Rear gear ??

Etc.......

Thanks......

404ci and the same cam but it is spec'd for a single plain. cam peaks at ~6900 i shift lights at 7k 3.90 rear gear. 28" tires

What would you like to know specifically?

Our shop car when it was cam-only and 6 speed ran a single plane intake manifold with our Polluter V1 camshaft.

bumping this back up........

Who's single plane and loving it ??

info that would be appreciated......

IVC @ .050 ??
what rpm does TQ peak at ??
what rpm does HP peak at ??
cubic inch ??
gear ??
tire ??

And a dyno graph would be killer.....


Thanks...

This is the drivetrain section, but I like you Okie and will let it slide Chris
346ci

You have a point, just thinking most manual dudes come by here so...you know...lol.

Ok, so same cam just a manifold swap ??

That Fast peaked real, real early......thoughts ?? Matter of fact, that Fast setup looks weird.....peak TQ @ 5300 and peak HP @ 6100...??

Thanks for the graph by the way !!

Different dyno's will load the engine differently and produce different torque curves.

Just giving you crap, you coming down to run Sunday?

Yeah, honestly not impressed with the heads and they're being swapped out. SCR was 11.9 with 1.875 stepped to 2" headers.

I do believe an elbow would have helped the single plane make better power down low, but it wasn't an option with the stock hood.

Given the intake manifold is only one part of the intake system, simply changing it isnt going to make a huge difference. And ultimately camshaft is going to dictate rpm's available.

With a 40-42 IVC that thing would match the fast intake torque and the same peak power it does with the 47 IVC.

Thanks for the info Chris....by the way, what heads (if your at liberty to say).......and my wife would kick my azz if I went racing the weekend before x-mas !! But, all these high pressure systems moving through.....it sure is tough to just sit here and watch them go by.
But I promise to make it to your shop and spin the rollers when I make a change......would love to hear your input on the car.

I hear ya Steve......but rest assured....a cam change is in discussion. But probably gunna do one change at a time. As to extrapolate a definable delta......

Now that is interesting Martin......and scary....

Wonder if some basic inversely proportional logic could/would apply ??

(single plane) 40-42 IVC = peak TQ @ 4700-4900rpm (346")
(fast 102) 46-48 IVC = peak TQ @ 4700-4900rpm (346")

So take the average 41 and 47, add them and divide by 2 = 44. So, what would 44 = ?rpm? with a single plane ?? And oddly enough.....my current cam is 44....lol

Here's a Trex cam(47*) in a Camaro with Fast 102 through 4.56 geared 9", 28" slicks and 54lb clutch assembly, fwiw this car we built made 500rw on another local dyno...

With your compression addition you've discussed that would be ideal.

The only problem IMO is your current cam does not have enough overlap to beat out a similar grind with tighter center lines.

239/246 .624/.595 107lsa 104icl.

If you really want to try to stretch the curve out and sacrifice some peak and under the curve put it on a 108lsa/104icl
