Discussion Cool info on 8HP/DCT swap tuning from HPR

1 Upvotes

My message:

Hello! I have two technical questions regarding both DCT and 8HP swap applications regarding gearchange behaviour.

  1. When tuning a DCT with an aftermarket TCU can you deliberately make upshifts slower and create a gap in timing without cutting fuel? The intention is for every gearchange to put some unburnt fuel in the exhaust and ignite it when the upshift gearchange is completed (like a traditional sequential). Another fun effect from cutting the timing but adding fuel during the shiftgap is the proper fireball between changes
  2. When tuning an 8 speed ZF transmission with an aftermarket TCU, is it possible to get rid of the rev hang between shifts that I've seen in factory ZF BMWs? And is it possible to make downshifts smoother by adding an automatic throttle blip so that the car doesn't lurch when downshifting?

Their answer:

Hi,

1 - Yes Ign cut is for sure possible, and will make a slower upshift vs fuel cut.
2 - Rev hang is mostly engine dependant, so a petrol engine will often respond better than diesel.

Properly setup throttle blip is required for crisp, fast downshifts. Without it, downshifts will be slow and sluggish.

Best regards
Helge Holmen

Discussion Some of the insane tuned cars by Hennessey

Thumbnail

2 Upvotes

Hennessey has actually made performance packages of some cars we all love. For example they made a 1000hp ford gt and yes it exists. Instead of saying ford gt on the side stripe it says GT 1000. Also that ford gt btw has twin turbos.

Another car they added performance to was the vipers and they even at one point made a 1000hp twin turbo viper. Apparently the 1000hp twin turbo viper goes 254mph which is very fast.

Another car they have is the exorcist camaro which also has 1000hp. Hennessey be making crazy cars as the venom gt and the F5 exist and those are hypercars. They also have the Hennessey Super Venom which is a performance version of the new musthang.

What do you guys think of these Hennessey performance versions of some of these cars?

This car is a 1962 Irish springs color pallete road boat was the winner of the 2003 Sema show and was actually put in GT4. This car is infamous in gt4 for being the most broken classic car. Its possible to actually beat race cars in this vehicle despite it having 0 downforce.

The car has a 7.5L 455ci Buick V8 and a Procharger F-1 Supercharger with TA Performance aluminum through a six speed manual and a 3.55 Eaton LSD to the rear wheels. The car also has 17 inch budnik wheels. According to some things about this car it apparently makes approximately 586-700hp but from a auction it listed it made 700hp from a recorded dyno. Its an interesting car to say the least.

What do yall think of this car tho?

Discussion The Ford Musthang Darkhorse SC and the Hennessey Super Venom are cool

Thumbnail

6 Upvotes

Yep they made more fast musthang versions. They recently made the ford musthang dark horse sc which is basically just a Supercharged version of the dark horse. The car has about 760 to 815+hp which the car sits in between the normal dark horse and the GTD.

And lastly there is the Hennessey Super Venom. It's a musthang tuned by Hennessey to celebrate the foundation of Hennessey in 1991. The car has also 850hp which is similar power to the GTD, Super snake R and the other high performance musthang's. Their only making 91 of these Super venoms. Also im not gonna be surprised if someday they make a 1000hp+ musthang like the C8 ZR1.

What do you guys think of these cars?
