Big HP stock gears

This is another one of my foolish questions.

In the old days it went like this build power , blow trans, build trans throw driveshaft, fix drivesahft, break rear, fix rear break axel. By then you want to go faster so you start all over again.

But seriously how much can those tiny gears and axels deal with before they grenaid

Here are the thoughts of Bill Hahn, concerning his development of his Neon and Eclipse race cars. The PT got an upgraded transmission and axles, from what the Neon has, ... so some of this is even better news for us!

"Our continuing development of the 420A will now explore what we can achieve when we are not limiting ourselves to the 450 or so HP airflow of the stock components. Moving effectively to the next level prompts us to finally take off the stock manifold and other parts that had performed so well to date. It's a bittersweet moment, for while we look forward to the huge power gains enabled by the new parts, we will miss the outright simplicity, ease and affordability of the stock parts. No matter. In order to maintain our position as the authority on these engines under high output, we will now forge ahead to ever-higher power levels. The information learned as we cross the 500HP mark will continue to benefit all of our 420A Turbosystems and engine components. We plan to persist until we have achieved the 400+HP per liter of engine displacement we have achieved with some of our other notable engine programs.

P.S.: The transaxle these engines are coupled to is a nice piece in its own right. Its durability definitely makes the engine's strong points even more viable. In the worst case scenario we've been able to come up with, our 98 Eclipse RS has withstood thousands of miles of turbocharged street use and 11.7 second quarter miles. It weighs about 2900 lbs. with driver and has a completely stock transaxle, uses slicks at the track and has had ZERO transmission issues. I've never missed a gear in it in over a hundred dragstrip passes. It's a perfect marriage with the Stage IV clutch we provide. I drive it hard, and if it holds up to what I dish out, then it's a durable gearbox! The fact that the stock components have held up to this brutal power level for so long is evidence of the durability that you can expect.


Of course, it has been my intention to push these components to their limits and beyond. This is the best way for us to understand what you, the buyer, will ultimately need to know about these cars and their capabilities when power is increased. If you are considering drag racing your car as continuously as we have run the RS, we heartily recommend a limited slip differential, and a training session from one of our drivers to teach you how to get that Hahn RaceCraft power to the pavement effectively while maintaining good drivetrain life. We'll gladly show you what we've learned about extending drivetrain durability and traction effectiveness. We believe it's the best way to make your experience with our equipment even more enjoyable. We have the information. That's why we drive, and race, what we sell!"

Thanks,

Bill Hahn Jr.

COOL

Thanks Bob

I am definately doomed to be broke for years

Are we talk'in auto or manual tranny?
