GR Supra 101: Routes to big power

[alfi.mke]

HPFP, Injectors, etc

Is that like the stuff Spool performance offers?
Seems pricey vs a PI setup?

I'd actually be interested to see what the guys with upgraded HPFP, Injectors and LPFP are getting away with for boost. Not much difference E60 to E80 tuning wise.

I'll never run that high of boost since I track the car.

I have the Spool fx350 (uninstalled) and in the process of sending it back for the FX-400x they just released. I've also been waiting for my injectors from them... it's been a while but the new FX-400x won't ship until early January. I don't have a delivery date on the injectors even though I've asked twice.

Should have everything installed and tuned by the end of Jan, unless they don't delivery in time. Really looking forward to running some higher E content fuel. 60-80 range. Pushing higher boost is also appealing. "Should" be able to support that. Will report back.

Crazy part. I have IP installed but not using it. Meaning 1050x injectors installed in my manni, wire harness, just no controller. Waiting on bm3's version of Reflex. I want to see how far I can push DI only until then.

Ah, so you can install the PI setup, and not run it while you wait then?

You can install the Reflex, PI, E sensor whenever. The key piece of info is you need a tune to run PI or an upgraded turbo. The reflex wiring, PI and E sensor can be installed but not utilized until you are ready for a turbo upgrade and tune. Once you are tuned for PI Reflex, you have to utilize those tunes and keep PI functional. Meaning you can't just unplug the Reflex, unless you have a non PI reflex tune too, but most don't.

Yes

Just hacked into Spool's network with Hugh Jackman from Swordfsh and Dade aka Zero Cool aka Crash Override from Hackers. Looks like your injectors will be delivered in two weeks.

Needed that lol

I didn't get that memo. I track my Supra in E45 on an aftermarket turbo. It's all in the tuning. This whole "everyone needs PI" BS is so boring.

A good amount of people using E50+ with DI upgrade on aftermarket turbos as well. The whole PI thing is needed to make power is so last year.

Why do you prefer DI to PI?

less hassle...

no port controller, extra wiring, 6 more injectors to look after, the only upside is you gain some valve cleaning ability with the port injection and you can run straight E if you wanted to plus have pretty much unlimited headroom for fuel.

if your planning on making less than 700 or going faster than a 9 second 1/4 isn't in your future agenda than a DI system is more than enough to have a fun street/track car

Way less failure points is why I prefer it. I've had too many things go wrong on track on my cars and ones I have supported. The less to go wrong, the better in my book. +200whp ain't going to help at all if you get a DNF.

First of all, please be careful when making posts like this. You know....

Second, this thread reads ' Routes to big power' you cannot make big power without PI, something EOS, and approval from the Cabal.

Any reliable figures I can get from a post I want to try and DI to fueling and make everything as clear as possible for the 2 routes

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 does add 6 more injectors, is the easiest way to not have to worry about cutting fuel to help the HPFP. While there are some hidden benefits of DI, when dealing with race fuel or Ethanol, those benefits are lessened.

Ether way, it takes fuel to make power. So as long as the DI or PI setup supports your goal, they are both fine.

I like PI because it can support whatever i want without cutting the fuel. And i find it to be even a little less expensive than the DI upgrades needed to support a fraction of the power that PI does. But again, not everyone wants all the power. and DI only can work for those owners.

what figures do you want?
