KB 2.6L max. power

[Riptide]

Assume stock heads, cams, and a 9.8:1 aluminator. Assume adequate fuel system in place.

Approximately how much power can one expect to extract out of a 2.6L stage 2 kit with 93 pump fuel?

Just looking for some estimates trying to get an idea of how much this blower has in it.

93 is really the limiting factor here.

Around 18-20psi/650-700rwhp-ish on pump 93.

The blower is capable of a little more with some race gas or meth and other upgraded goodies, bigger tb/tube, porting, bigger heat exchanger, overdrive crank etc. etc.

Thank you. Just kinda looking long term here for when the stock engine eventually comes apart on me. Then it'll be time to build it and that sounds like more than enough to blow my hair back.

On my built Stroker 3V, 9.2:1 Compression, Stock Heads with Comp 127300 Cams, 2.4 Kenne Bell @ 17#'s, my car was making 558/552 to the tires through the 5R55.

I was pretty much at the max with that blower. I had 2.75 blower pulley with a 10% O/D Innovators West Balancer.

As far as trying to do it on pump gas, I don't know why everyone is so hell bent on making high power on pump gas.

 

[Riptide]

Not hell bent on it just wondering what the ceiling is that's all.

 

[Vapour Trails]

More than you'll ever need or want.

Probably true in my case. lol

I would also say around 650rwhp on pump gas. With other bolt ons such as full exhaust/tb/ bigger heat exchanger etc more around the 680 range. And if you want to go all out with heads/cams maybe around 750rwhp.

 

[GrnBullitt08]

I think your gonna see right around the 550-575rwhp range, with a snow performance injection kit your could probably see numbers above the 600+ mark. I would go with the 2.8H kit Kenne bell offers, I have seen a few cars making well over 800 with that unit. I believe that both were 5.4s though

I have to ask, where are you getting these figures from?

You're not going to make 750RWHP with a 2.6 on a 3V.

Look at the size of my blower pulley.

You're not going to get much more boost out of a 2.6 than what I was making @ 20#'s of boost and 600RWHP, and not much more than that. Over 20#'s the 2.6 blower is no longer working efficiently and generating a lot of heat.

intake/exhaust/ full bolt ons running 20 pounds of boost should be easily 600rwhp+, shoudn't it? Figure in heads and cams and I would think you could get it in the 645-660 range. And I got the 750 number from my tuner who told me the 2.3L TVS could support 750. Maybe he was wrong. I'm not an expert and I don't claim to be one. Just passing along what I was told.

Thanks but I already have a 2.6 and am not looking to replace it unless it breaks. I may put the stage 2 tune and TB on there but that will be it for me until the engine blows up. Then I'll pick up the pieces and move on. With luck the heads and the supercharger will be OK.

I was at 600 at 20#'s through an auto with the cams. Higher numbers through a manual will prevail. I'm not debating your tuner, and when they say that a blower can" support" x amount of power doesn't necessarily mean that you'll make x amount of power with your setup.

Im at 483 with stock block,cams, etc at 10psi. I do have bigger TB,lt headers, full exhaust w/ xpipe, msd coils, etc...

Ive been told once I built my bottom end (forged pistons/rods) I could do 20psi and easily be at 700...Is there something I am missing? I would think 700 would be pretty easy to gain

You would probably gain 100hp with 10 pounds of boost and the supporting mods, but that would be around 600.

Is that 480 on a dynojet?

 

[BoostedGT480]

You would probably gain 100hp with 10 pounds of boost and the supporting mods, but that would be around 600. I think a stroker would add 40-50hp or so too, so that with a bunch of timing, heads and cams might get you to 700.

I just edited it the same time you said that..lol I meant to say I think getting to 700 w/ another 10 or more lbs with more fuel would be pretty easy...

I get what your saying and I agree 750 is high but it should be able to make 600+ with bolt ons and 20 pounds of boost.

adam at st motorsports whom pretty much specializes in kb blowers would be able to give you a very good estimate, i do believe he told me about 700-750ish area but they maybe with heads and some other little things.

I was at 605RWHP on a Dynojet with 19-20#'s with an aggressive tune (23* timing, and 12.5 A/F) using C16, and we were pretty much at the extent of my blower.

I switched to a 2.8 Mammoth same boost 19#'s and I'm at 608RWHP with a less aggressive tune (20* timing 11.5 A/F). We swapped the stock balancer for my I/W 10% O/D Pulley, gained 5#'s (total of 24#'s) no changes to the timing or A/F and the car made over 700RWHP, but I was running out of fuel. So until I change out to the Fore Triple Pumps, she stays at 608RWHP.

But what a difference 5#'s makes with a more efficient blower.
