    Thumbs up TPC Racing 600HP 3.7L Cayman Turbo: Can you handle the Power?

    TPCicon Racing, we just finished up a record shattering 3.7L Cayman Turbo! When we finished putting the 3.4L Cayman Turbo back together that was originally in it, the owner of the car wanted more power and something that would stand up to constant abuse. After sitting down and discussing the options, the 3.7L was the way to go in order to take this project to the next level.

    To do this, we had to tear down the engine to machine the block to transform it from a 3.4L to 3.7L. After machining the sleeves, the block was ready for TPC Racing custom forged pistons and connecting rods. By doing this, we were able to drop the compression from 11:1 to 10:1. This improves the torque in a huge way, making for huge torque while the boost comes in very smooth.

    The owners initial goal was to reach 500 wheel horsepower. The first run we made without modifying the boost, we were able to put down 470WHP. Mike knew right then that 500WHP would definitely be attainable. Mike did some fine tuning and turned up the boost and ended up making 515WPH! That calculates to about 600HP crank! When driving this car, it is a true experience. The power comes on so smooth it's like it came from the factory that way. It is a pleasure to drive with normal drivability like our other turbo kits, but once you start applying power and the boost starts to come in, you open up a new world. Pull up to a 997 Twin Turbo or a Corvette Z06 and just pull away from them and leave the owners scratching their heads.

    This is the most power we have gotten out of a 3.7L Cayman Turbo build. The lowered compression and custom internals of the engine allow us to run higher boost for a longer period of time. This 3.7L Cayman Turbo is the most impressive Cayman I have ever driven. Each time I drove it, I did not want to get out and was left with a smile that I could not get off of my face. It is just amazing! The car is now being shipped back to it's owner in Saudi Arabia.

    TPC Racing: 600HP 3.7L Cayman Turbo. Can you handle the power?

    So, what's the advantage of boring out to 3.7 l, vs using a 3.8 crate motor? What's the approx cost- more than $25K?

    Saudi Arabia has some specific rules about cars engines, and changing to another engine is a real PITA. It is easier to modify the original block than to do a switch out.
    I believe that was why they made that choice.
    It's also cool to say you have the original block, that is worth status points galore in my book :-)
    I would be interested to know what the approx. cost for such a build would be. If it is in the 25k range, that would not be bad for a Vette or TT killer.

    Good news. Your impression and assessment of the 3.7L Turbo would be greatly appreciated after you've had some time to evaluate it properly. Good luck.

    Awesome!
    That should be good for a 10.6 second pass.

    It's going to be a monster for its owner. All's well that ends well...

    I'm sure everybody here knows the past two years were very nerve wrecking. And at this point my eyes are on the shipping company to clear the car from the US Customs before the deadline... I'll keep you guys here posted.

    Now aside from the groundbreaking Horsepower figures presented by TPCicon above that pleased me, the enthusiasm and passion of my ten years old boy (Sayf) about the outcome truly made my day. The attached screen shots speak to my heart louder than any exhaust note

    PS the attachments are personal, but I'm sure Porsche-fellows here can relate to them

    I heard this car run on the dyno last week, and it is truly a monster. I don't know if it's the fastest Porsche in the world, but I'd be willing to be it's the fastest Cayman! I wish I could have gotten a ride in it before it had to leave, but there wasn't time.
