From what Paul said to me at the RR day, his torque figures are circa 5% less than a DD RR IIRC. Regardless.... that is some hefty torque by anyones standards.

 

Consider Steve Simpson, Steve Simpson Motorsport, Warton, Near Carnforth, North Lancs. Straight up the M6 for you. Discuss your requirements with him especially if you are thinking about a Simtek. simpson.msport@tiscali.co.uk

 

Cheers duncan mine is 8 miles away sorted time for re mapp lmao ....

 

So I had a remap with 10% (well, 5 litres / tank) of this stuff on Friday last week. Remap courtesy of Simon.

Previous deltadash power on one bottle of NF / tank (expensive!!) was: 353bhp / 354lbft @ 1.4 bar with a td05-20g.

After remap with 1.5 bar - 391bhp / 392lbft! Deltadash figures again, obviously, but using exactly the same settings as last time.

It certainly runs a lot nicer now, throughout the rev range. It idles cleaner (I'm not sure if a whole bottle of NF / tank is detrimental to idling?), and there's more torque across the rev range it feels like. As an example, earlier my car wouldn't pull at all in 4th at 1800rpm on a flat road - the engine would just make noise and vibrate a bit. With E85 it pulls away cleanly (obviously not super fast, but it vibrates a whole lot less).

The above is with a 2.5" decat exhaust as well, with prodrive back box and a centre silencer still in place.

Very impressed with the Simon's mapping and the new fuel so far

I already had a remap booked in where I was just going to map out the NF and run on standard petrol for cost reasons, but then this thread came along so I decided to give E85 a go. Essentially it's free octane booster, and on my car it works heaps better than NF.

 

Great post Henrik - thanks for sharing. Your gains sound similar to those I experienced when I switched to 10% methanol. As I said earlier in this thread, I'd love to use a good slug of E85 but alas, no filling stations within 100 miles of here

 

How accurate do proportions of E85 and petrol have to be? The Morrisons at Wellingborough is about twenty-five minutes away, making this marginally do-able. But as a chemist I tend to get a bit wary of: "put in x litres when you're at the 1/4 mark and then top off with V-Power." Obviously the timing adjusts, within reason, but how much leeway is there?

I run down to the petrol light and then put 5 litres of e85 then 45 litres of petrol - easy as

 

Have you a methanol filling station ?

Greenergy deliver E85 (admittedly motorsport quality and more expensive) but they still do it

 

Quite a bit of leeway - mine's mapped for 10% methanol but I've run it on straight V-Power sticking to lower boost and up to 15% methanol. Paul said that the best way to err on the side of caution is use a little higher % methanol (or E85) than lower.

 

It doesnt have to be exact no.
A couple of % either way should not cause an issue

 

Sort of - Have a mate with large garage and I have up to 420 litres stashed there in two large drums...

 

Nice fire risk there - 420 litres of liquid that you cant tell if it is burning until your face melts off

 

Duncan - you're fixated with invisible flames and fire risks The drums are sealed metal drums (you can't just open them by unscrewing a lid ) and the garage is stands on its own halfway down a field. Following the logic of your argument, no garage or workplace would ever store anything flammable on their premises. I just think you're jealous that a) I only pay 71p per litre, and b) litre for litre, methanol is a better octane booster than E85

 

I think I do have a fixation with that tbh.

HPA - Methanol - Incident Management

No jealously though - I am very happy with running 100% pump fuel to get 600 lb/ft

 

Pulling your leg matey I'm envious of 600lb/ft too and that you can get E85 and I can't. I'm down at Zen all day Thursday if you get the urge to show me what 600lb/ft feels like on the road
Cheers
Andy

 

Cheers guys - sounds like something to plan around.

Got a graph from JGM now:



The blue is the old map with NF, the red one is the new one with E85.

The relative torque increase was biggest at low revs, so no wonder it feels so much more alive in normal traffic now

 

graph is difficult to read.. I'll see if I can sort better quality one tonight etc

 

Simon is there anything to be gained from switching to a E85 mix from a methanol mix?

Click on it, it will open up bigger

Or check it out here: http://www.bilar.co.uk/subaru/graphs (at the bottom)

 

Anyone have a link to greenenergy, cannot find anything using google

Banny

 

difficult to answer at the moment they seem fairly similar power output wise..

Need to play more on the same car on both..

if there was a morrisons that sold it accessabl;e to me easily I would try it on my own car.. might see if I can pass one.

Simon

 

much clearer

 

err Greenergy International Ltd

 

Any idea how much they charge for a 50 litre drum of E85?

 

£59.85 plus VAT + delivery

 

Once the ECUTek is taken off of my car I think I'll try this as opposed to a NF mix. I take it with 10% you don't have to worry about changing fuel lines, fuel tanks etc.

 

Why taken off - just get the map changed for 10% bioethanol?

Shouldnt be an issue.

 

Hi Duncan,

I've recently purchased an 05 WRX to develop my skills on OS tuning(and EMS mapping in general) with a view to working up the stages. (Currently running well on Stage 1)

I'd like to broaden my skills with tuning the Spec C as well, and plan to ask Andy to remove the ECUTek software soon. Since Morrisons is only 40 mins away, I'd like to give E85 a try.

 

Here is some information from Greenergy.

and

So buying two drums or 100 litres the price to me works at £1.70 per litre so I think I will wait until Morrisons Supermarket fuel stations start stocking this as a matter of course.
