Max RWHP for 2V on stock bottom end

[uvbnhad]

What is the max a 2V with stock bottom end can take. I'm probably just being paranoid but I've been comparing my car with some of the ones over on MPH and with similar mods and they seem to range in the 405-413 rwhp range. I've always heard that a 2V will handle 450hp before you run into problems. I'm assuming this at the crank which leads me to another question I have that I'll create another thread. Should I be worried with the setup I have planned or should I be safe?

400-420 rwhp is the limit.

By the way you have not mentioned your new setup on the forums yet

A lot of people will tell you it depends a lot on how good your tune is, and I've seen some people go over the 500 hp mark with turbo's still running a stock bottom end. I would limit it to under 450 to be on the safer side.

I'll take care of that now.

Yeah they are capable of 500 and more but its the longevity of the motor that limits to the low 400's

The 2V rods are in question after the 400-450rwhp mark, some have been lucky and met and/or exceeded the 500rwhp mark, but its a time bomb.

I personally hit 503 rwhp for quite a few months before mine went boom.

My opinion, stay under the 450 rwhp mark, say closer to 400 with a good, safe tune and you will feel better about it every time you put your foot in it.

I personally know a guy that ran 640 rwhp with a turbo on a BONE STOCK longblock Gen 2 Lightning for about 8 months, then he turned it up to 738 rwhp, lifting the heads in the process. After it cooled the heads sat back down and he drove it for a couple of more days before the motor went Boom.

The last one that was done on our local dyno made 465rwhp. I stepped outside the shop doors just in case a rod came flying at me from inside the engine.....
It was an '02gt stock bottom end with Vortec 13-14lbs boost w/cooler. It could have made a lot more but old man Joe backed it off to about 425-435rwhp.....

400 rwhp with a good safe tune and it will be plenty reliable. I'd still be looking to swap to a Bullitt intake soon, the stock plastic one just makes me nervous with a power adder whether there is any real risk or not.

I know this is kind of off topic, but what do you guys think my setup will be doing on stock internals?
-Procharger D1SC intercooled at 10 psi
-Anderson power pipe
-Accufab 75mm TB
-C&L upper plenum
-x pipe
-exhaust
-tuned with Diablosport
I have been told to run a conservative tune going with the 10 lb pulley and not to go into high rpms...

Depends on your tune which leads to my question of...... Why the predator and who is going to tune your car with a predator?
