XDI HPFP vs Livernois HPFP

[bpd1151]

On my stock motor, with OEM intake plumbing, and a single, 10lb. nozzle on Alky Controls Meth Kit, and many other mods NOT on my car at that time, LMS got me to 435awhp on a relatively conservative/mild (custom dyno) tune.

IDK where you, or others would be at, but that's where I was before ramping up to their fully built, long block conversion race motor, & a host of other supportive, go fast goodies to get me where I'm at now at 617awhp.

Hope that's of some help???

There have been a couple guys without built motors that have posted 11's (11.99ish) with meth and/or just an ethanol tune with Race gas along with some weight reductions such as seats removals etc...

Their supporting mods were mostly just CAI and Downpipes along with a tune.

I will caveat this by my own personal experience that those tunes are most likely pushing or are beyond the boundaries of these motors in stock forum. I would not expect to run those times consistently. It's a combination of driver skill, good air, and luck. I suspect that those motors are at risk of throwing a rod... I have a tune that is consistent with the datalogs posted by guys running those times and I can tell you the motor is being pressed hard.

Being as LMS is very conservative with their tunes, if they say you will get into the 11's I'm sure they mean it, and safely. They are not going to put their name on a package like that just to have motors going kaboom... they don't operate like that. But it comes at a cost as you can see.

Just my humble opinion.... I wouldn't expect a tune only with DPs and a CAI to last long pushing into the 11's...

Like my old man says... "I can get any car to run a 10 second 1/4.... once!"

I emailed the XDI HPFP group the other day and we chatted back and forth a little. They said their HPFP is not yet available (website says otherwise) and that it will be soon. They will not sell the part direct to the consumer, but only through Unleashed or Brew City Boost. The 35 version is good with a BAP and stock turbos for straight E85 and the 60 version would need a bigger pump or good BAP, upgraded turbos for straight E85. He didn't mention injectors, so I assume the SHO they are testing with is a '13+.
