there's absolutely nothing wrong with DI only setups pending you stay within the limits of the HPFP. depending on a persons power goal DI can suffice and be fine.
My recommendation is if you even think that at some point you may want more than 700-800whp just get PI. Port injection while it...
Extra fueling capacity is extra fueling capacity. Doesn't matter if it comes from DI upgrades or a port injection upgrade. any time or power level is attainable with enough fuel and air. not sure why people think or thought 9's or faster wasn't possible once upgrades were available for DI...
Unless you got lucky. Most if not all Supras do not have that bolt.
Remove the DME cover, and unplug the Z11*6B connector from the Integrated Supply module.
This cuts power to the Injectors, Ignition coils, and Vanos solenoid. This will in turn, not allow the car to start.
Get in car...
See below, this is stock powered supra giving moderate acceleration on the OEM diff mounts. You can see how much the diff moves and why that can attribute to things breaking.
Cloned ECU is only a need if you want to use ECUTEK for the flashing platform.
Bm3 custom rom and MHD plus can both be loaded onto the ecu during the unlock.
Go to BM3 website for info on gains.
Twisted Tuning full rear diff lockdown brace kit now available for A90/A91 Supra and G29 BMW Z4. This kit was designed to stop the rear diff movement and slop in the rear. We went this route for bracing because it saves time and energy not having to remove the OEM differential mounts to lock...
Are you going to have port injection?
Either way, yes the stock HPFP and LPFP supports full e85. However for max power e40-e50 should be run without port injection to work around the HPFP fueling limit. The stock LPFP is not an issue until surpassing 700whp. The HPFP is.
The stock LPFP is good for 700whp. So yes with port injection 600whp is achievable on ethanol.
93oct....I wouldn't push more that 525-550whp due to octane.
The stock HPFP only supports 500-535whp on decent concentration of of ethanol (e40-e50) with normal safe AFR.
Used this event to test some new things coming out for MHD. Only ran 30-33psi here as we had some small issues. That's what happens when you change too much the night before an event. Lol... more info in the video description, but this was the one full pass at 30-33psi we were able to make...
