I was finally able to take my 1995 FWD Hyundai Accent, with a hybrid 2G motor / EVO 9 head and automatic transmission to the dyno. Results were impressive, the project made 588HP and 448 torque. This was accomplished with an EVO 8 computer, pte 6765 turbo and E85 fuel.
 
Aeromotive a1000, alot of people use double pump setups at those power levels but i would say a1000 with full braided lines to the fuel rail. Good luck i would love to see what this runs and what difference the head makes.
 
Ive seen dual 044 run lean in a friends car, maybe someone else can give feedback on that? Mechanical fuel pumps are pretty pricey theyre usually for people making well over 1000whp depending on your budget check weldon they are high quality pumps.[DOUBLEPOST=1413034653][/DOUBLEPOST]Also what size fuel line are you running?

Page number 2 has a video of the dyno pull. My pump arrived today have 800hp date on October 29. My new fuel system consists of Walbro in tank 255 pump supplying fuel to a two gallon surge tank. Magnafuel 4303 from surge tank via #12 and to fuel rail via #10 to 2150 fic injectors.
 
Install Magnafuel 4303 pump today it is in very loud on initial start up I hope this is normal. Car starts and revs like a champ again can't wait to strap it on the rollers see the numbers it produces.
 
That's gonna flow something serious, I am wondering if you have done any cam timing tuning? I am very curious if a little more overlap till the turbo builds boost would help the turbo spool faster. Then as soon as exhaust reversion becomes a problem, retard the cam and depending on what rpm your spinning to advancing it again? Is it either full advance or full retard or can you have it anywhere in between?
 
I have not done any cam tuning as yet mivec is activated at 2500 rpm and off at 7000 rpm. I am tinkering with the idea of using a boost curve to mimic a mivec map and using that to have full control of mivec.
 
Did you notice better idle and off boost to spool response? Not sure what cams your running but if it makes a set of 272's more like 264's driving around town, then its an even more worthwhile mod. Cause it is extensive ( hopefully not expensive) work to do the machining but, cheaper than an evo LOL. Nice job man!:applause:
 
No special machine work was done just had to block off a some of the oil drain holes in the evo head. It was simple bolt on affair, compared to when I had an evo 8 block with 1g head and fwd 1g transmission this was a piece of cake.
 
Last night while preparing the car for dyno today I noticed that as I rev the volt meter drops to 10 volts might have to change alternator today before my dyno session
 
Oh I guess I was thinking of kiggly's thread on the mivec head on 6 bolt. He mentioned something about drilling a blind hole a certain depth. But he may have come up with an external line set up. Is that how you did it, cause I know the mivec spool valve is hydraulically operated.
 
Awesome, I'm really interested in what was done and what is needed for this swap. And my bad kiggly was using a 2g head adapted for mivec on 6 bolt block, thats the blind drill. I ask because a lot of people said it couldnt be done and it wasnt worth it.
 
You need a complete evo nine head, wire harness and computer would make things easier but not necessary. Some of the oil drain holes in the evo head need to be closed. Other than that it's a bolt on affair. I relocated my oil filter as I don't use the original OFH. I welded two #8 an fittings on my oil pump one pushes unfiltered oil from pan to oil filter relocation unit where I am able to adjust my oil pressure from 9psi at idle to maintain a healthy 90psi at red line 9000rpm. From the oil filter clean oil is then pumped into the engine through the second #8an fitting. Turbo and mivec feed #4 an lines are located there also. So far I have not had any issues with oil filter seal blowing out before if I did not allow the oil to warm up and rev oil filter would loose it's seal.
 
Thanks, I have a date with dyno tomorrow at 1pm. If everything goes well with my new fuel system I should be able to achieve my goal of 700hp before the cold weather and snow arrives.
 
Leaving the dyno a little disappointed made 577 hp but had to end pull at 7000 rpm as ignition started to breaking up. Numbers might look low but this is through an automatic transmission. I was able to get the tuner to use my boost map to control mivec dyno graph after the map was installed showed that the car picked up power without touching the tune. Looking for help with an ignition system. So many out there what's recommend for 800hope.[DOUBLEPOST=1415883626][/DOUBLEPOST]After doing the math 577hp with the auto transmission this is approximately 721hp if the car had a manual transmission at 33psi can't wait to take it to 45psi also my fuel pressure Gage is not steady needle fluctuates is this normal with a big pump.
