Started as a 4E-FTE with 190HP on 1.3bar boost through a hybrid CT9 .
Not enough so in goes a brand new WEPR TD04 kit and Sidewinder exhaust system running just 0.8 bar and made 225hp......then 1.1bar 250hp.......then 1.4bar 260hp
Got bored with the TD04 and the small 4E so 5E time. Plus the emanage blue was removed and an Ultimate was fitted along with a new cylinder head and new cams. 320hp
Then the ugly monster strikes again and tells him he is bored! So time for a Direct Port nitrous kit! 425hp
Still not enough having reached the limits of the 4e ECU an the emange its time to change to full standalone....Haltech PS1000 440hp
Still not enough
Out goes the TD05......time for a larger turbo kit.
and a dog box conversion
And new head This head consists of the following: +1.5mm intake and exhaust valves Bronze Guides Race spec Valve seals Solid buckets (no shims ontop of the bucket) for safer higher reving Custom Valve springs Machined for 4AGE head studs Ivan Tighe Cams (Custom spec and ordered seperate from the head) Weisco pistons
New intake manifold
had quite a large signal noise problem on the RPM signal, the car had to be safe tunned due to the ECU reporting the RPM to be anywhere within a 600-800rpm limit e.g. if reving at 6000rpm the ECU may go into the 6800-7000rpm part of the map or equally it could use the 5000-5200rpm part of the map, both of those situations could be catastropic to the engine so it never had the timing advance it should have had.
So this problem had to be fixed time for new crank sensor fabricated up a trigger wheel onto an aluminium crank pully.
Up to now all this was on 109 Octaine race fuel with 4.5% oxygen content. Time to try something a little different and learn from the Americans. So the car is being converted to run on 100% Alcohol for when on the drag strip!
Alcohol is 114Ron but only a Mon of 99 which is the same Mon as the 109 race fuel used before, the key difference is the oxygen content on the Methanol, this stuff is 50% oxygen, so not only is your turbo and nitrous system cramming in oxygen but the very fuel itself the car will burn an will also add oxygen for a power increase, typically 20% addictional power in a like for like situation. Methanol burns very cool and allows 3bar boost to be ran with NO intercooler, benifits of this are less lag, however Methanol needs that much burnt that the exhaust gases are way higher than normal and lag reduction will happen anyway.
Unlike Petrol based fuel that run on boost anywhere from 11AFR up to 12.5AFR, Alcohol is very different and requires twice as much to be pumped in and typically requires an AFR of 4.5-6.0. Because of this much much larger capacity fuel equipment is required. Also Methanol is very corrosive so all of the fueling side ideally needs to be Methanol compatable.
A high capacity fuel pump, in this case went for a mechanical pump driven of the cam gear like those found on GDI engines.
A high capacity fuel pressure regulator is also needed to cope with the increased flow from the pump.
1.8bar on Super Unleaded made 402hp 1.3bar on Methanol made 414hp.
No nitrous yet on any runs but its looking promising.
did 2.1 bar on methanol here is dyno sheet
managed to squeeze 520hp out of the clutch before it started to slip, still not had a chance to use the nitrous.
So the goal for 2012 is a cool 500hp motor, we think even 600hp.
