Thank you. The displacement on this engine with the new bore and stroke is almost 4.1L. It is ~ 4.05X but who is counting The engine project 4.0L is still very much parts at this point. We have the crank, pistons, rods, bearings, liners and other misc bits here. The engine case is being prepared with our 12mm head studs. The heads are being machined as we speak and we are waiting for the larger titanium intake and exhaust valves to arrive. We have some new valve springs going into the heads and we are almost finished with our solid lifter conversion which will be utilized as well.
We hope to have everything ready to assemble in the next few weeks. Once we get all of the misc loose ends sorted, we will officially begin building the engine and I will go into details about each step. Thanks for your enthusiasm
Is the 1100 hp and 9000 RPM just an educated guess? If the parts are still being put together is this just the area you are shooting for?
Not saying you are not going to do it, just wondering what you are basing these numbers on.

It is a conservative estimate. The last 3.8L we built made 1037 AWHP on our Mustang Dyno at 8000 RPMS. I think we will tune this one to make about the same power as the 3.8L but achieve it with 25 PSI of boost at a higher RPM.

996TT - 1/4 Mile Speed = 150 MPH
996TT - 0-300 KM = 14.41 Seconds 997TT - Standing Mile = 196.7 MPH

Yes it will. The crankshafts between the 2 engines are virtually identical. We will also be releasing our direct replacement standard 76.4mm crankshaft shortly. It will feature the same features as this long stroke crank but it will retain the standard stroke. This crank will be a tremendous upgrade over the stock crank for those not wanting to go with the full conversion.
AMAZING can you pm me pricing on this? Do i need a custom length rod as well?

That is just isnane you guys! 9krpm redline? You guys never cease to amaze me with the quality of work you do. Sometimes I wonder if auto manufacters' should take lessons from aftermarket parts companies. They might learn a thing or 2.
I am coming up with an 8.1L block that puts out 1500 HP but i have to tow it behind the porsche or find a way to fit it in the front!!! We see who can do better...
Now my question is, How good is Superglue?

Once we have this engine built, tested and are satisfied with integrity, we will be offering the 4.0L conversion as a complete engine with power options from 900 - 1100 HP. We currently offer our 3.8L conversions with power options from 900 - 1100 HP. I will to get the pricing details ready after we finish the testing. If anyone is interested in pricing for our current 3.8L conversions, please PM me.
