2176 this time

[buguy]

So i think this one is going to be a 2176. I picked up a new 78.4mm CB crank from a guy at a show a couple months back for $200. Couldn't pass it up. Grabbed a new aluminum case and a set of those fancy light 94mm drag race JE pistons and AA cylinders on the AA black Friday sale. Also got new bearings and a few other misc parts for the new engine. I haven't worked out the details on it yet, but i think I'm going to make a high rev engine this time. I also ordered some CB 5.6 VW H-beam rods so it should make some pretty good power. I'm going to call and talk to Pat D more about it, but it will probably get CNC wedge ports or maybe super pros. Undecided on those and cam until i make a decision on the rpm. I'd kind of like to make it an 8500 rpm screamer just because it would make nutso power and I've never had an engine like that, but also, not ideal for the area i drive. Most likely will pick up a new BW turbo for it too. It will have to get/make a new header and maybe go to a 2.5" intake instead of a 2". I should have a fuel system that is already up to the task. There is a chance i will hit more in the middle, like maybe 3500-7000 rpm... Just have to see what i come up with. This will be a slow build since i only have 15 miles on the last engine i built.
I thought I'd put it up here to get some thoughts and ideas.... And of course to document it for later reference.

Like you said , In your area u drive 8500 rpm
when I ran N/a with IDA's 8k was the place to be ,,
just get an old FK 10 ,,, biggest heads u can afford,, you'll thank me later

Nice parts, but have you ever been at 7.5 -8k on the streets?

I'm verry comfy at 5 - 6k with my turbo, hauls ass!

What's your goul with this bug?

Nice parts, sweet pistons, crankcase seems to have change a bit in the casting since mine...
is it normal that there is no case saver?

[buguy]

I have never driven anything at 8500 rpm. I know what your getting at, but keep in mind just because it will rev to 8500 rpm, that doesn't mean i will have to run it there. I don't expect it to make no power everywhere else. This is definitely a concern of mine though. The engine i have now seems to drop off around 6000 rpms and it hauls too, but it leaves me wanting more. Really I'm more concerned about my new trans. I ordered it when i had the 1600 so i got one geared pretty tall. 3.88 r&p with a 3.80 first and stock for the rest. That's why i mentioned maybe hitting it more in the middle of the rpm range. Kind of up in the air right now. If i can size the turbo right, i feel like i could make enough power down low to be satisfied, and still be silly in the upper rpm range. Really don't have a goal for it. I would imagine turning decent rpm it would make way more hp than i would ever need. 400-500hp would probably be about where it would land.
The case came with 8mm case savers and 10mm case savers that the user has to install. It also has all 6 shuffle pins.
Mike i considered the fk10 and a bit bigger with a web 86c. Kind of depends on the heads.

[madmike]

Largest cam I've ran was FK87 in my dragster, it seen 8+ grand every pass
But the FK 10 ain't no slouch , I'd glading go with it again, instead of the fk 8 , if i only had one in stock,lol

[rubenski]

So it your goal 4 to 500hp?

Like i said i really don't have a goal. I just assume 400-500 is what it will make. With E85 I'm almost not limited at all to what kind of boost i can run. It will be more dictated by where i want the power to come in at as to what turbo i choose.
Right now, as i said, I'm running a 2054 with home ported 40x35 AA heads with a Web 163 cam (.505" lift and 250@50). I also have a small 1 3/8" header and a small WRX turbo. I broke an axle after only 15 miles, so i don't have a real good feel of it yet. I know the exhaust and turbo are too small for it, but i wanted to get the engine worn in a bit before going to crazy with it. So far I've seen boost at 1700 rpm and it feels like it drops off around 6000 or just before. Which is right in line with that cam.
I'd like something that pulls more rpms. Not necessarily more power, but that kind of comes with it.... and i wouldn't be mad about that.

I think with a set of CNC/or someone with a reputation and E85 you’ll have what ever you like. I think your current set up with a bigger turbo would be a nice compromise but I get having parts and building new. I’d look at the Fk cams or one from Shag.

Agreed Mike. That should put me about where i want to be. I was also looking at the Web 86b and 86c. 86b has a little less duration but with more lift which i would think would help on the top end and maybe a smidge more on the low end.
I actually think while the engine i have is out i may retard the cam 4 degrees and see what it does for me for more rpm too. If i can pick up 500 more rpm it might give me a glance into what it's like for more street rpms.

Agreed. My exhaust now is holding it back and the heads are not going to allow a whole lot. Along with the turbo as you said. I'm sure my current engine could be bad ass with just going a little larger on the turbo, and the exhaust, and then giving it some proper boost. Which i may very well still do. Header first. I'd kind of like to see what this 19t can do. I was actually going to order a CB turbo header during the sale but it was out of stock.

Something else I'd like to do when i get to this point, is put some speed sensors on the wheels. I think it would be fun to try traction control!

I need disks up front but it’s doable for sure and Super easy.

You can get the sensors cheap on Amazon

Yeah? I haven't researched it at all. I remember Clone did something but i don't remember the specifics.

I ran one just to see it work and it does read and gives me the option for perfect launch or time based launch control until I get some disk breaks up front.

Then it’s a driven wheel compared to non driven
