Default Reaching 600whp reliably - 06-05-2019, 04:17 AM

So I'm full bolt ons / including Cobb intercooler, 09 335i automatic.

Everything that fails has been replaced. Vanos, injectors updated to 12s, every gasket on the engine, head taken off and rebuilt, boost solenoids, rb external pcv, bms highside catch can, new valve cover and gasket. Transmission serviced and tuned. I mean it's too much to list
I have 1.75" rb inlets and vsrf outlets sitting in the garage

Thinking of going with vargas single barrel system, I already have stage 2 fuel it lpfp. Then going with the new pure 600 turbos.

Running jb4 with custom bef on 93. Dont really plan on running e85, but I do have access to it.

600whp reliably on this setup?

Maybe an oil analysis? Or if you're really pro-active maybe replace the rod bearings? I suspect increased bearing wear on cars that are really being pushed. I could be wrong but for ~$150 in parts it's worth it if you can do the labor. Bearings are like $100 and then you need new bolts too.

I probably wouldn't say anything is "reliable" at 600 whp though. Just more reliable than if it weren't replaced lol

Gotta remove the crankshaft right? Would require removing the transmission too. Eek. That's basically a full engine tear down.

If I went that far, mind as well replace pistons and rods as well.

Not at all, crankshaft stays in the engine. It's about the same as an oil pan gasket job, as long as you can drop the pan you can gain access to the rod bolts and then the bearings.

You'll need to remove the oil pump and the oil baffle though. There's a $20 bolt kit you'll need, I can give you the part number if needed. These cars are full of one time use bolts. Mind you I did this with the engine on a stand so it was a lot easier but you don't need to touch the transmission or any of that stuff.

Shoot, I might just do that then. I'll take part numbers please. Thanks!

These guys have the bearings, I placed an order over the phone with them at the time. Good people. You'll need 3 sets of these, should be like $95 after shipping. Mind you these are the STANDARD size replacements, if you check my post history you'll see I used these and Plastigauged them to check clearances. Unless your crank was previously ground down then stick with the standard size bearings.

Oil pump screw set = p/n 11410426472. You need one of these, I had a few extra screws leftover after the job was done. I think this is normal, I replaced whatever I removed.

Oil pump pickup tube gasket = p/n 11417527092. Just need 1, dunno if it was super necessary but I did it. Might as well include it.

Oil pump bolts = p/n 11247589671. You will need 12 of these.

Also you'll need an oil pan gasket and new oil pan bolts

I also did the oil level sensor o-ring while I was in there

I'm not sure I'd ever call 600whp on an 110k mile engine reliable, at least without a full check of internals. This for street or track?

Are you planning to run a ton of meth with that 93? Be tough without some E85.

Just a weekend street car.
Nah, just straight 93. I guess if I had to add an e mixture

Considering Pure themselves rate that kit at 500whp for 93 you'll probably need something.

I have a 600whp Pure set up. I run full E85 for added safety.

I may have to do full e85 then. Get a 55 gallon drum and put it in the shed outside

What fuel system do you have? I'm hoping the stage 2 lpfp that I have now coupled with the single barrel hpfp upgrade will feed it enough fuel.

Think I'll run map 5 when I'm on 93 cruising, if I plan on having extra fun I'll switch to map 6.

Can you do that with a custom bef? Swap between the two if you have a bef for e85?

You can swap bef , but pain in the ass. Thats why I do full E85. I used to blend but also a pain. I have dual walbros and port injection.

You wouldnt want to be doing 550whp without ethanol or methanol in my opinion. I expect you'll need around 24psi to achieve 550 and 11 degrees of advance.


UK FBO 335i, GCs, JB4, PI meth, BMS CP, OCC, Braided brake lines. Diff Lockdown. TMAP sensor, custom bucketless stage2

11.79@119mph on stockers, CP meth (UK, Santa Pod)
11.74@129mph on GCs, custom port meth injection.
