What does the size of the turbo have to do with running stock rods?

Amount of boost maybe? Plus it would be good for safety, Cleaning up sharp edges on the rods wouldn't hurt ether. Plus he plains on spinning the motor pretty fast. the 3/8 studs would help hold solid bearing tolerances at those rpm's spoken (9500) reduces the risk of a spun bearing.

Nope, try again.

Edited decided to enlighten the question i was asked in a knowledgeable manor..

Yeah, high RPM's would be the only concern I would have with running stock rods. Even then, upgrading the rod bolts goes a long way. Stock rods will hold up to lots of abuse. The size of the turbo and/or the amount of boost you're running don't mean anything. 30psi of boost on a 16g isn't the same thing as 30psi on a turbo like this one.

Yes I agree the only time stock rods usually fail is when the engine is getting over powered by detonation. Witch usually happens when people try to push the package on pump gas.

Honestly Rod's do have a tensile strength to where they will start to deform. Just like any metal..

I like to play the game I know nothing about these thing's, I get asked the least stupid question's

I know 30psi is pushing hot air on a baby 16g.. Honestly 30psi doesn't even fit in the 16g category with me. 25psi maybe.. If it's not holding it don't force it! That's how I shed light on that situation.

This S475 LOL has a better compressor map upwards of 40psi actually! Not to mention would work wonders on an inline 6 RB26/2JZ..

People have made north of 600whp on totally stock 4g63 bottom-ends. I'm not saying that means anyone can do it, but it can be done and has been done. 30psi on a 16g is totally doable on the right fuel--say E85 or meth for instance. It's actually pretty common nowadays, lots of people are running that setup. They just yank the wastegate off the little 16g and let it spike to the moon. As long as you know what you're doing as a tuner, you can get away with a lot of stupid shit.

Well 600whp on that stock bottom end wasn't made on pump gas lol. All the power is made in the head and turbo setup fuel delivery and the tune helps it play nice. Vise verse..

I wouldn't recommend removing the WG no matter how good the Toon is LOL that turbo is still only designed to spin at certain levels of RPM's

I don't know anyone who has made 600whp on pump gas on a 4g platform, period.

That would be like some other worthless world record

Tony Turk did it with his 2G and a GT35. 621whp i believe.

This motor will be a test bed. It is not like I am going to try and mae 1000whp with it. He has nothing but time to tweak his setup. I would rather learn than jump in. And learning with a big ass turbo iswht we wanted to do. It IS ultimately where he wants to be, just working through his own issues as well. But one step at a time and we have a legitimate shot at making 800-1000whp with this car.

Really? 621whp is good power for a 35R even on real fuel, let alone pump gas. Sounds hard to believe...

Whoops. 600 on pump and 721 on race gas.

I'm not trying to talk shit or anything. I've actually met Tony Turk before and seen his car in person. I wonder what his best trap in the 1/4 is. If you work really hard on tuning for a peak number you can probably get that number pretty easily. That's really low boost to be making that kind of power too, but the torque is so low, that's just crazy to me, I can't wrap my head around it. I also can't believe how lean they're running it. I wonder how much timing they've got in that thing?

COuldn't tell you. All I know is brad brooks is the man. I swear he was right near 140mph traps. But, they did window the motor first trip to the track, then tony parted it out. But remember, that header design made a HUGE difference in that car versus others. One way to tell is to listen to the exhuast. Sounds nothing like most dsms. Much more open and throaty/raspy. And that Tial housing all made it efficient. Just like you said above, boost is irrelevant. The torque is low because of the design on the car. It is a top end monster and was setup to be that way.

I can't wait to have videos for you guys on jason's car. Hopefully tomorrow I can work on the tune some more and get some more boost in it.
