Title: Adding methanol to your petrol....
Post by: MS1COYS on 24 September 2012, 14:39
I've asked this in my thread in the mkv section and got bored waiting for a reply.

Is it possible to add a percentage of Methanol to your tank of petrol, relatively safely. I've heard of people adding up to 25% on Impreza's and realising an extra 10% bhp.

Help us out forumites  :kiss:

Doesn't methanol eat rubber? Wouldn't it destroy all the fuel system over time?

No point as to get methanol to work it has to be a really high combustion and you need to use twice as much as petrol, so adding a little to your fuel will do f**k all. Well it will run clean and cool.

So nowhere near as efficient as Wmi?

if its not a good idea then why do the evo, impreza and skyline boys swear buy 10 or 20% to a tank.

some of my engines have run really high meth percentages.

tho mixing alcohol with petrol is not top favoret for me, problem being your alcohol needs to be completly dry to mix with petrol and moisture in it and it won't mix.  i prefer to use 2 fuel rails 1 with neat petrol and the other neat meth and use the ECU to control the percentage of whats injected.

the carrot for useing meth are the following.

its equivalent ron rateing is much higher than pump petrol  its around  110   :smiley:
methanol mops up heat , the injected quantity allon with laten heat of vaporisation  drops intake charge temps very nicely on boosted cars can be a pita on NA cars in cold weather tho.
you need twice as much but its less than half the price.
even on a std compression engine you can see good power gains even on NA,  seen 15% gains on stock compression NA 16vs,   with turbo cars it allows  higer compression ratios, more boost, more spark  and reduces issues of heat soack  espectaly in drag raceing situations.

favoret mix todate is  49 % methanol  48% nitromethane 3% propolyene     (  that'll give you a big power NA valver that can scare the 20vt lot )

So where can I buy this gear. Any links? Also will my ecu regulate the mixture, or will I need yet another custom map?

Post by: danny_p on 27 September 2012, 00:10
pump fuel is a random mix of crap anyway.

for running dual rails and useing the ecu to controll the mixture of fuels the engines getting  you would normaly use aftermarket managment,  it is possible to use std ecu's to do it but some wireing alterations have to be made,  and some serious reworking of the ecu's programming not just the map.

you can get piggyback meth or water meth systems  of varying qualitys and capabities. 

randomly adding methanol to your fuel is probaly not the best idea  in the % concentarions that your goig  to get awway with with no ill effect your not going to notice much.  pump fuel is 5% alcohol anyway iirc.    tho its an ethanol blend  as its not poisonus wheras meth is pritty nasty stuff. 

what do you want to acheve and from what engine ?

ko3 mkv gti. running currently 300bhp. fmic/tbe/induction/fdv.

would like to up the octane rating. It runs better on v power but its not readily available where i am. ive also filled up with bp102 once and it felt like i immediately gained a considerable amount of bhp.

your not man enough for an m3 just yet  :grin:

Wouldn't mind the FQ, but at nearing 80k miles things are going to start going t its up.

My brother in law is selling his M3 CS 2006 (Comes with 19" standards and uprated brakes all round)

He said I could have it for £15k (Its on at £21K) A tad sluggish considering the 'stigma' attached to M3's, but having said that 'Clubsport' said they could remap it and take it from 340bhp and 270lbft, to 375bhp and 330lbft and take the limiter off, so rather than the mundane  :shocked: 155mph it should be good for 190mph.

I borrowed it to go to Newastle Emlyn in Wales in January this year, when my Jag was in the garage and it was a very nice car. Totally planted and returned nearly 26mpg on the whole journey.

Plus which it would be nice to own a rwd drive car! I couldn't bare to buy an mx5, boxster,, z350, 328 etc just to get into the rwd circle.

If I really wanted something brutally quicker than anything else then I'd buy a custom build quantum/caterham kit car. My friend owns the company linked below and he could build a 450kilo, 350bhp kit car, that would smash anything. His personal Quantum vx (7 replica) has twin turbos, has a dry weight of 530kilos and produces 440bhp. Just under 900bhp per tonne  :grin: 0-60mph in 2.3 seconds (Quicker than a 1000cc British superbike), 0-100mph in 5.2 seconds (quicker than a Veyron) and 0-150mph (top end) 12.1 seconds (quicker than a Mclaren F1)  :laugh: :laugh: :laugh:

Did you check out MG's link I posted? They do an awd/4wd conversion from a, cosworth derivative. It does however add nearly 250kg's to the dry weight. But still 440bhp. 780 kg's dry weight. AWD I think this will blitz anything anything on the road. Better power to weight than your average bsb.  :whistle:

just stole this info from here

http://www.spanpodyv.pwp.blueyonder.co.uk/gsr_v_rs.htm

 The RS model weighs in at 1260kg instead of the 1360kg for the GSR, although weight could be reduced
  further on the RS model by opting for the thinner gauge body, or by asking for a car minus the aerodynamic
  appendages. RS packages were basically the same, although the optional wheel and tyre combinations were
  naturally bigger, in line with the standard GSR fitment, and a crossmember support bar was added each time
  the larger wheels and tyres were specified
