Default My Quest for Idiocy (S400SX 67mm FMW)

Well, things are starting to come together after a LONG time (started planning in February and purchased engine first week of April) so I figured I might as well start my build thread now as I suspect it will still be a few months before I can start dialing it in.

My primary goal for the car is... to be retarded. The car still will be driven on the street but it is going to see a chunk of 1/4 mile time and I would really like to run it in mile racing and aim for 200. I know that is going to be a tough cookie and I will need a lot of aero work but a challenge is fun.

The car is my MBP 03 bugeye.

Short Block:
ej257 sleeved & o-ringed case
Coswort 79mm Billet Crank
+2mm 1200hp rods with L19 rod bolts
Custom coated 4.030" 9.4-9.5:1 pistons
ARP case bolts
King bearings
KillerB Oil pan, baffle, and pickup - also looking into doing a dry sump setup if oil pressure isn't satisfactory with the modified oil pump

Heads:
Version 7 ej207 heads
CNC'd chambers
Ported
+1mm valves
Springs & retainers
Kelford 282in/278ex cams - from Kelford:
-Duration @ 0.25 mm: 282 Inlet/278 Exhaust
-Duration @ 1.0 mm: 240 Inlet/236 Exhaust
-Net Valve Lift Inlet: 11.50mm Inlet/11.00mm Exhaust
-Suggested Centerline: 130 Inlet/113 Exhaust
ARP 625+ head studs on the outers, but P&L (as sad as I am to say I have a P&L part on my car this was the recommendation) 13mm head studs for the center two studs
Aiming for 8800 RPM if the turbo can keep up

Turbo:
S400SX 67mm FMW 1.25AR T4 twinscroll
Rated to 95 lb/min and I went with the larger turbine housing as I plan on doing my best to max out this turbo and where I bought it from made it seem like the boost I want to run might choke on the 1.1 AR turbine housing. I figured I can swap out to the smaller turbine housing later if need be.


Intake Manifold:
Seeing xdrian's car made me decide to do just an NA short runner manifold for now, but I am considering doing the ASF "monstrosity" if I end up needing more flow. Update - this will be hogged out to accommodate a 75mm throttle body though, should help a good chunk.

Exhaust:
FobiaWRX is making me a twinscroll foglight mount exhaust manifold for dual Tial 44mm wastegates, should be pretty badass and he thinks he might be able to ship it as early as next week some time.

Intercooler:
The current plan is to run an air/water intercooler in the engine bay to a heat exchanger where my current front mount is. Between this and the exhaust manifold, the piping should be extremely short.

Engine Management:
Vipec v88 is what I am looking at, currently, for when the car is going to be turned up to 11
For lower boost and break in I plan to run it on the Carberry ROM and see how it goes

Fuel:
The car will be broken in on 93 and after that it will spend most of it's time on 100 octane or other race gas and have "set to kill" 1/4 mile & mile racing tunes on E98. Also planning/considering on adding a smallish shot of Nitrous down the road when things are more ironed out.
I will put in ID2000s when it is time for e98 and I have a set of APS twin injector TGVs if I end up needing more (not sure I will, but I figured I wanted a solution available in case e98 + nitrous is too much).
I will try to get pictures/exact info of the surge tank setup I plan to run, it is one a guy locally built with integrated Magnafuel pump that another car locally plans on running but on an S300 FMW I think it was. It looks amazing and right up my alley.

Drive train:
07 6 speed with R180, it will probably break on me with my luck
Exedy Triple Plate
Carbon fiber drive shaft
DSS rear axles
Brembos
Currently 5x100 bolt pattern, but will be swapped out for 5x114 with a stud upgrade
Current wheels/tires are 17x9 Mach V Awesomes with 255/40/17 star specs

Suspension:
To be determined/researched

Depending on when the engine actually arrives I may either go straight to the Borg Warner or run my old setup for break in and to try and actually hit 10s with it instead of my old best of 11.01 @ nearly 130:
FMIC/EWG/HTA Green (now with AMR 10.5cm hotside)

Update 11/30 - heard from Benson, block should be done with o-ringing in the next week or two. So with the holidays, realistically I think I might be able to see the engine being put in maybe mid January if I am lucky.

Update 12/13 - Back from Benson, getting assembled in a few days

Update 1/8 - Awaiting buckets then assembly, woo!

Update 4/23 - Round 2 coming together, updated some parts that changed

Yeah, I know there have been quite a few out there that have taken much longer, and I'm still no where near done. I am praying for mid summer but who knows, the engine build has been kind of a chain of sorrow. The place I ordered the engine from has been super friendly and helpful, but between Manley's crank fiasco and machine shop slowness/screwups we are about to tick the 8th month from when I paid for the engine.

Is it just me or does that turbo look FREAKING HUGE next to that cute little vf. Solid build man, I'm on the fence about going all out 750+hp with mine.

Yeah, that part of the build has been a bit depressing.. I wanted to run the green this last summer and do this over winter, but kept running into major set backs with the engine. I am glad I picked a quality builder though, they were in final assembly a few months ago and found one PTW was like 5-5.5 thou or something like that and told me about it before fixing it on their dime. Not only that, they calmly and seemingly happily put up with my calls every week or two checking in.

I can't really bitch too much, the problems aren't their fault and they just keep solving problems as they come up.

Yeah, the frame size is pretty nuts. What I particularly like is that same frame size has turbos up to 125 lb/min in case I need to go larger for my goals and if I want to test my builder's parts ratings experimentally.

It is an MPS build and while the delays are unfortunate, I still think they were the right choice for the job.

Edit: MPS is building the engine, but Six Star is going to be doing the rest of the work/installation.

If your targeting that rev range with that turbo I would re-think your cam combination.

Also I wouldn't run anything less then 9:1 compression no matter what but that's just me.

Look forward to your results regardless.

Haha, Dom seems like a really good guy. I mean he has put up with a million and a half questions from me...So far...My motor hasn't even been built yet either, still waiting on pistons to be made I know it's not MPS and I try not to push Dom on that topic, but it's frustrating.

Where in the midwest are you? If you're anywhere near me, I may need a ridealong when you're done

Oh, and you should change the title of this thread, it's not a quest for idiocy, it's a quest for insanity.

That is the largest non custom exhaust cam Kelford makes and the 2nd largest intake for these heads. I know I might want to go larger, at least on the intake, though.

Chicago suburbs, so not too terribly far, haha.

Got some more parts coming Monday:
Five-o 1400s
2x Tial 44mm wastegates
1x Walbro 460c

In thinking about break in, I won't be able to generate any meaningful boost at a reasonable break-in RPM with the S400SX so the HTA Green will have to go in for break-in so I can see ~10 psi at a reasonable RPM. While I am at it, might as well see what the HTA Green will do on E on a real engine.

Then when working the kinks out of the S400SX the 1400s should be okay for 93 and 100 and when it is time for kill on E98, APS twin injectors + my current id1000s + vipec v88, or just id2000s + vipec v88. The Walbro should be enough to keep the surge tank from emptying too quickly I hope. I might need to do some math on that.

I might be doing this wrong so someone let me know if I am.

If I have id2000s running at 100% duty cycle at high rpm (worst case scenario perhaps?) at 43.5 psi of fuel pressure that would be 8900cc/min of fuel that is 141 gallons per hour.

The walbro 460 is capable of flowing ~460 lph at 0 psi so it should flow 121.5 gph.

So at 100% IDC, there would be a drain of 20 gph on the surge tank of 1.25 liter per minute. Does that sound right?

Wastegates and fuel pump are in. Got some pictures from fobia on my new header and it looks awesome!

Equal length, large runner, 2x tial 44s, 2 bungs (front o2 and wideband), 4" vband exhaust dump (might have him make a "downpipe" with a 4" cutout to run to a catback if it is just too loud).

Edit: After reading again, I think you mean that the flex sections should be normally straight instead of being set with a bend probably so they don't wear/fail or something like that, right? They look straight to me in those pictures.

Let me try to work on a pic to describe what I'm talking about...

Here:



If you switched the flex pipe and that circled piece of tubing, you would be able to make the bend to the turbo flange easier and with less bending. It seems like it would be very difficult and restrictive to bend it the way it is now.

Understand what I'm saying or is it just babble to you? Or am I just a moron?
