Blue is rpm and white is air charge temp.

I was seeing close to 70c on last trackday without it, no logs though unfortunately, it was a much hotter day tho but it doesn’t make massive difference to overall ait.

The nozzle sprays at 4-5psi boost same as the secondary fuel pump.

Nozzle size is 640cc and is on or off, not progressive like some.

What was the days air temp?

[Bakerboy]

DRLane Low teens centigrade. So around 8-10c less than the previous track day I attended.

I should have done a run without the injection on but just didn’t think to.

It makes a huge difference, it was evident as soon as I start using it on the road let alone the track.

The rotor pack is coolish to the touch after thrashing it.

Yeah - Maybe it was making a small improvement, but that’s likely compounded by the low teens temps. Try this when it’s > 30° C and I have little faith this does anything.

Is this Syvecs ECU logger software? Looks cool. Did you upgrade the IAT sensor to what Gareth recommended (threaded Weber?)

Thanks for sharing man!

Not sure what the threaded Weber is in all honesty.

The programme is s view, the display programme for the data logging feature of the syvecs.

To reclassify the difference with water on or off is polar opposites.

I will try and do a run with it on and off on same day.

It stops the heat climbing nearly as far and then recovers really fast as you decel

I tried this with varying nozzles, and boost levels and couldn’t get a material impact on track. When it’s < 20°C I generally wasn’t having issues anyway as the cool ambient air was a huge power improvement.

If you’ve found success then that is awesome! I’d be excited to explore it again in the future.

Here in Colorado USA, we’re high altitude and very dry heat. So most cooling efforts and or strategies are put to the test.

Keep us posted as you experiment.

It’s well documented that it works, however you need to have a issue with heat in the first place for it to be able to do anything and take heat out.

What platform were you doing it on? Was it a charger?

Doing it before blower should have a pretty drastic impact as the intake air doesn’t get scorched up to temp from the hot compressor blades, and once the meth is past the screws it aids in cooling the charge coolers then the actual charge itself.

Also worth noting: My charger is spinning faster than oem kit as running the larger main pulley, this in itself will create more heat.

I’m also on a Harrop running 9psi. We spoke offline about the Syvecs a while back when you got their stage 2 tune. My car is fairly built track machine.

You’re over-indexing success in very tame conditions. Again, I do not think this would do anything in hot ambient conditions.

Yeah I remember, so your saying you have experience running the meth through the blower?

Time will tell how effective it is in summer, all I know is it rises a bit but caps the hike in temp unlike without, and as soon as you decel it quenches the heat that’s been added very quickly.

still waiting to see some 60-130 results from one of these on 85 running some worth wild boost.

Do you have any data from yours you can share i.e. the 2011 E90M3 ESS G2, Active-Auto X-pipe, with RK FULL E85 tune?

[RUG8RB8]

I have been absent for a long time, my apologies been crazy busy with work and traveling. I was looking on here to see if any new items have popped up concerning active E-85 real time adjustments based on measured (FF sensor) ethanol content. Lo and behold, on the BPM site, I see that Mike now offers a new software upgrade in conjunction with the APE flex fuel sensor, and the Harrop is an option not just the ESS and VF Engineering. I am curious if anybody has opted for this yet? If not, I have already sent out an email through my friend Brandon at Performance Technique. If this is a real option now, I will order and keep everyone posted about results.

Heat soak, I think we must get the type of sensor and location replaced. Seriously, think that is a must. However, I daily drive my M3 still, quite heavy actually, have nearly 60K on the car post S/C. Yes, Mark I am past due on S/C oil change and still cant find good instructions on how it can be accomplished safely in the car. That being said the car runs flawlessly both in heavy CA traffic and on open road mountain twisties. It has literally, Never had a hiccup.

[Soden82]

I do not mean to derail the thread in any manner. I did want to build on the previous post and say that is BPM is working in conjunction with APE to provide true flex fuel capabilities for this platform, then I think many supercharged M3 owners (whether it be harrop, ESS, AA etc.) will want to utilize this.

I know in the northeast it is hard for me to obtain E85 consistently, and then it has to be drained and replaced with 93 octane once the weather gets cold and the ethanol content drops for the winter blend.

[OmairK]

Considering the Harrop kit... Was also about to pull the trigger on the Infinity Auto Design Intake System. Will the intake port of the Supercharger 'Plenum' match with the intake? At first it looks like it might but I don't think it will.

Does any intake system (Dinan, AFE, MS, Eventuri, etc....) match up to the Harrop Plenum Inlet?

Thank you!

[BlackPhoenix]

I cannot say for the other options that you mentioned, but I was able to make the Technocraft intake system fit quite well. I was not able to get the elbow to fit, however, but I’m quite happy with the end result.

[nycplumber]

Has anyone ever looked into porting? Corvette guys get over 50whp from it.
