Thats great Ill have to get saving thats my target! Cheers guys
How much am I looking at for water/methanol injection? and where would you recommend trying to find?
You're probably looking at £300 for a AEM complete kit, then get it mapped with Kpro/K100 big power gains out of water and alcohol between 10 to15% with good set-up/tune, I think it's well worth it IMO! Imagine hot summer days, no loss in power when driving the car hard!
My set up will be a full race progressive Aquamist methanol kit so not cheap at all!
Im gonna change out the brakes before I do too much to the engine so, which big brake conversions are you guys doing and what do you recommend?
Im thinking Tarox 6pots for the front, drilled rotors/red calipers?
Ah right thats cool what gains in bhp do you think id be looking at for the £300 job? and it doesn't sound cheap but I bet it will be amazing! Whats your car running bhp wise at the moment?
water/methanol injection as well?
Water/meth injection is pointless on an NA setup because you don't run high enough intake temps.
Typically you get anything between 0C and 10C above ambient temperature depending which intake you have. You can get higher obviously if you have a shocker of an intake. You can add all the ignition timing you want (within reason) at those temps.
Water/meth only becomes any use on boosted applications where intake temps can get as high as 60-80C depending on which charger you have and whether you use an intercooler or charge cooler. At those temps, yes you are restricted to the ignition advance you can use before it starts knocking. Even then, water/meth is the thin end of the wedge.
Basically water/meth on a normal NA build is unnecessary.
On the subject of water injection my Evo 6 had it installed. It was the aquamist kit and it was activated when the intercooler spray button was pressed. It also had a small leak on its reservoir which used to annoy me (not that i used it). The install was messy too and I was actually thinking about removing it before I sold it.
You can see the blue piping for it here.
Loxy on my set-up I will be using a top mount intercooler so for sure my intake charge will be higher than a front mount one don't you think?
Yes.
Seems a very very odd place to put it when you have the option of behind the front bumper. Even with the scoop, you'll get nowhere near as much airflow over the intercooler compared to the bumper option, plus it will be sat in the engine bay, just above the rocker cover and with the radiated heat from the gearbox and exhaust manifold.
Seems like on bordering on a lunatic idea if you ask me. You'd get better results from a front mounted intercooler. It's not like you're saving lag by shortening the pipework, it's a Rotrex not a turbo.
That's your car though, it's up to you.
Water/meth on an NA car is still pointless though.
What Dotty meant, I think, and what I meant by it being the thin end of the wedge, was that you have the car mapped with the injection all running fine, then some time down the line you get a leak, failure or whatever, the map is still going to be forcing a load of ignition in and the car will be knocking itself into oblivion.
I'm not saying it doesn't work on a boosted car, it does. Lots of people have run it, loved it and not had issues. Others haven't been so lucky.
Personally I'd just get the bottom mount Rotrex kit and fit the bigger charger. No need to be messing about with injection, and you'd have a healthier slab of torque from the bigger charger.
