I'd love to get the 10psi pulley from you but I'm to much of a pussy to try it on my stock engine.

 

[Towelly]

Those numbers seem okay. What is your altitude out there in Idaho? I bet that has a little bit of a role in your numbers. That torque curve looks awesome. A friend of mine has a 2.6KB at 10PSI and he makes 470's RWHP and 470's RWTQ with a good bit of timing, plus full exhaust , and some other supporting mod's I'm sure I'm leaving out, in a manual car. So, thats not far off if this is a auto car at a fairly high altitude.

I'm at about 2800ft

 

[Riptide]

SAE corrections should account for altitude if you have those numbers.

Make sure you keep a good eye on the intake were it passes by the fuse box. If it ends up rubing a hole in the tube you will pull in unmetered air and run lean.

 

[Riptide]

Speaking of the "accordion" part of the intake it's kind of questionable IMO. Doesn't seem real durable and I'd like to replace mine with something stronger.

Anyone sell a good replacement?

 

[TexasBlownV8]

Yeah, that part is really hokey. Needs to be better.

 

[1lowtoy]

I made this one to use and stock stlye maf and a much larger air filter. The coated it to match the KB.

 

[fdjizm]

holy hell what size is that filter LOL

 

[Riptide]

lol yah that's huge.

I'm glad someone mentioned the rubbing problem with the edge of that fuse box. I checked this morning and there are signs of wear. It's hard to believe KB would sell a ticking time bomb like that. I don't even have that many miles on my car since the blower went on. Not very impressive.

I'd prefer not to fab anything up so if I can't find something pre-made for sale then I guess I'll have to just tape that spot up with some electrical tape and keep an eye on it.

 

[1lowtoy]

Come on guys, don't let your girl talk you into thinking that size doesn't matter! The filter ends in the same place the KB filter did, it also takes up the space where the lightning maf was. I don't remember the exact size, I'll look though some notes and see if I have it saved anywhere.

 

[1lowtoy]

One more picture for y'all.

 

[Riptide]

I'd do that if it didn't require another tune to compensate for the change in air flow.

After seeing the wear from that fuse box I'm concerned the same thing is happening where the intake threads through the cut in the chassis. When I go stage 2 later this summer I'm definitely replacing that "accordion" style piece with a new one or a fabbed up metal part if I can find one for sale. I'll put some plastic runner along the edges down there or worst case just put a couple layers of tape over the edges.

Do you have specs on what you used to make it? Instructions or notes? I'd like to make something metal and more like that as well. Although I'd still be using the 4" SCT MAF I'm using.

 

[1lowtoy]

The intake was make from a few 4 inch u-bends, just cut and tig welded together. I opened up the opening when the KB tube goes through the core support so that it wouldn't rub anything. On this one I added a MAF flange for the new style meter instead of using the lightning meter the KB kit came with. It isn't hard to do, you just need an eye for where to cut the u-bend to get the end result that you are looking for. I think ST Motorsports has an aluminium tube that they sell for the KB kits. They may do the same as I do and only build them for a car that I have at the time though. You may want to get them a call and see. The car I built this one for had rubbed a nice sized hole in the KB tube and ran lean then bricked a converter. It ended up kicking a rod out of the side of the block.

In order to use the SCT meter, all you would need to do is make the tube that much shorter.

Those HP numbers seems really low to me, I am running the KB 2.6L Stage 2 on my stock bottom end and first dyno pulls were 491 rwhp / 421 rwtq, I then added Kooks long tubes, no tune and ran 496/426 with 11 pounds of boost and an 11:1 AFR. I am getting ready to drop in the Comp Cams Stage 2 NSRs in and a quick tune to see how far over 500 rwhp I can get in the stock shortblock.

 

[TexasBlownV8]

...a B I G factor is how much timing you're running. Sure you can easily push over 500 with enough timing...is it safe? Well...
And automatics definitely put less HP to the wheels on a dyno.

Curious, cycosarge, if you datalog Engine Torque via SCT LiveLink, what values do you get? I see around 600 ft-lbs as 'inferred' or measured, perhaps through the transmission.

...we're kind of getting off topic, but to the original OP, hope you got everything squared away. These cars are very fun to drive with the extra power!!!

You will be out of Fuel Pump or MAF before you just out right blow it up. I made 507 rwhp for 3 years on stock motor.

@maxdmax

4.10 will sap a little power on the dyno.

Did you buy the kit new? I can't remember. I'm running the pulley it came with and typically don't hit over 8.5psi. Makes me wonder if the stage 2 throttle body makes a bigger difference than their documentation seems to indicate.

I wish KB was better about explaining things in their documentation. They are pretty clear about not exceeding redline and they refuse to raise the limiter over stock in their tunes. But they never really explain exactly why. Is it a limitation of their tune, not enough fuel capacity with the stock kit components, etc.?

I have been told the lower 4:10 gear effects the dyno numbers maybe 15 to 20 hp. Yes. it was a new kit and we are running the pulley that came with it. We had a boost gauge on the car when we dynoed it and it is was almost exactly 10 psi. I am pretty sure my builders asked for 10 psi (on my Son's request) so it may be a different pulley. I will try to go measure it this evening.

So I have about 8-9 months left until I blow it up with the "3 year rule"?
