JB4 s63tu world record @ 770whp /830wtq

[Mike@N54Tuning.com]

Saw this and thought it would be of interest to the group!

The test car (BMS Owned) has a JB4, BCM, BMS intake, BMS chargepipes, BMS methanol (dual CM7 nozzles, spraying 100% Meth), Dodson clutch packs, and around 95 octane fuel. Half and half 100 with 91, factory turbos, factory exhaust system including all emissions equipment, factory rims/tires, etc. The mods can be installed and removed in literally an hour or so.

Notes from the Run

1) Pushed boost up to 30psi to get power up to 770whp. What's interesting is that the JB4 monitors boost in both banks, while the passenger side bank produced 30psi the driver side bank running the same duty cycle produced only 27psi. If both banks could get up to 30psi we might see 800whp stock turbos and exhaust!

2) With the dual CM7 on 100% meth the car is still fuel limited. Trims maxed out around 28psi so larger nozzles my be in order.

3) The BMS s63tu intake seems to be worth around 15whp peak at this boost level.

Why did Terry take off the downpipes on is car?
I thought he had the ER Dp's.
Unless of course this isn't his car.

Terrys dyno is also a higher reading one 20-50whp I'd say. Not to take anything away from the run, or thread crap, but just as a point of reference.

Great numbers! Wonder what it would look like with downpipes?? Stock downpipes have to be holding it back.

That was their 2014. This is their 2015 with 3k miles on the clock. Downpipes have never been removed nor the exhaust ever touched.

I don't think that's really true. This dyno is owned by SpecialtyZ and is widely regarded as a normal reading dyno in Southern California. It's routinely a few hp less than EAS' dyno for example. For reference they posted 100% stock the car did 530whp in 5th gear on the same dyno.

Awesome! Terry doing it again once I get my clutches will see how far I can go. Great job T!
