Considering the ability to run straight e85 with a simple bolt on, and the fact that it's not much more expensive than the aux fuel kits being offered at the moment, I'd say it's worth $1599 to quite a few people. I'd just like to know its limits.
I've said for a long time that I'd drop the coin for one immediately for anything under $2,000. It's very much worth it to me to have a factory style integrated solution that's under the PCM's control. This will get me to exactly where I want to be, both now and in the future, and I won't have to worry about a secondary controller flaking out on me and ruining a good engine. I've been waiting a lot time for this upgrade and I'm very excited to see them coming to market! :clap2:
Considering the capabilities of the Bosch pump that I'm understanding it uses, it should be a VERY capable pump. I would think 500+ on E85 would be doable, but I'm sure Livernois will chime in with more on that.
Unfortunately not. Our fueling systems are more like common rail systems found in diesel engines. The biggest bottleneck thus far has been the HPFP on the fuel rail. However, not that that's been solved, I'm sure we'll be looking at the injectors next. Adam has said that the LPFP is good to around 600-650 hp and I'm sure we'll see a lot more testing on upgrades across the entire system before too long.
You won't need this upgrade on pump gas because you'll be limited by octane and not fuel flow. The factory unit is completely adequate for pump gas tuning. As you mentioned, this pump will really shine with E85 and different race fuels. The safe limit with 93 seems to be around 325'ish whp with most tunes.
Going to back this up as well, these pumps 100% out perform what the factory injectors are capable of. We as well found that the injectors cannot support the new pump volume.Hey everyone, sorry for the late reply, we have been getting hammered with inquiries on this (Not a complaint, trust us).
So, what the graphs are showing is commanded fuel pressure versus actual. As you can see with the stock pump, the computer is requesting a fixed pressure value, that when stock, is more or less, easy to achieve. When tuned, it makes it more difficult to achieve that number as extra power requires extra fuel, and it can no longer deliver what is needed. Add in E85 (of any mixture) into the system, and it just becomes more and more difficult to achieve. In the case of these graphs here, at full E85, we actually had to run less power and boost just to be able to not have catastrophic failure with E85, but as soon as we put our pump on, it was able to keep up with demand, and put power back into it.
Now, we have found the limit of the injector, so we will be working on that next, so we can confirm that the pump can definitely out perform what the injector is capable of.
Now, as for purchasing these, we plan on being able to ship these out in the next 2-4 weeks.
Yes, you can. The pump just has the ability to even surpass the limits of the injectors. That's a good thing. It means there's plenty of room to grow.
And the injectors aren't that bad of a cost up compared to the pumps at ~$640.
With the stock injectors, our pump has performed up to around 380whp under ideal conditions with e85.
You can run either e85 or 93 but both will require a tune with this pump. The computer will not be able to read the increased fuel so you will need a tune.
We are currently testing that! we are pushing it to the absolute limit to find a true boundary line of what it can handle.
Yes you are correct!
