GSX EFE 1986 , 1327cc , 11:1 comp. Fuel E85. Megasquirt by Arttu. Injectors: Bosch 700cc. Coils: Dyna green ones (3,0 ohm). One throttlebody from BMW 1100cc boxer engine. Supercharger: Eaton M62 from Mercedes SLK. Dyno:

That´s the clearance what I have been using in my "big blocks".

Now the pics works.

I made oil stat by bolting it to filter cover. All oil is by-passing cooler before oil temperature goes over +85 C.

The compression is approximately 9.7 with busa pistons and zero deck height by using Cometic 1.1mm thick MLS head gasket.

+1 for Ignitech. I have Ignitech TCIP4 in my 1360cc Cafe EFE. So far it has been working perfectly.

Aisin 500 is ok for engines 750cc or smaller. For Bandit 1200 I would choose Eaton M45 (750cc/rev) or Eaton M62 (1000cc/rev). If revving roots type supercharger to it´s given max rpm, it´s thermal efficiency drops = it´s making more heat than boost. You can google "Eaton supercharger performance map" and check for the best suited supercharger size for your bike/need. From my experience the engine needs about 300 m3/hr air flow / 100 rear wheel hp. About the compression ratio, if using less than 7 - 8 psi boost no need to worry about compression ratio if it´s less than 12.

I have SPS JR3 cams in my 1360cc EFE. SPS cams are grinded by Kent Cams, I think the JR3 cams are close to the Kent Cams street grind. Dyno results with stock cams (thin lines) and JR3 cams (thick lines).

No, it´s are Delkevic made downpipes for bandit 1200.

Yes you can. Bandit 1200 liners outer diameter is about 86mm.

I have Busa pistons in my n/a EFE. Piston to wall clearance is 0,05mm. Piston rings are same which come with used pistons. Engine is running good = no abnormal noises and oil consumption is nearly zero.

I have stock EFE cams in my supercharged EFE, intake 109 / exhaust 111. Throttle response is good and so is torque from idle to redline.

Nice and clean!

GSX 1100 EFE 1986 - 1327cc JE pistons 11:1 comp - mildly ported head, 1mm bigger exhaust and 1,5mm bigger intake valves - Original cams, intake 109, exhaust 110 . Welded crank - Eaton M45 supercharger from Mini Cooper S - Blow through efi - Boost 0,5 bar - Fuel E85 - 209,7 hp and 181 Nm (rear wheel power).

I have Delcevic Bandit 1200 downpipes in my GSX 1100 EFE. It´s not a flat 4-1 but it is quite close to the oil pan.

I have Ignitech TCIP4 ignition in my 1100 EFE project bike. It uses EFE´s original triggers and trigger wheel. In TCIP4 is option for TPS or MAP sensor. I using MAP. Have not ride the bike yet, but it started easily.

M14 x 1,25

Delkevic system fit and finish are ok. It´s made of stainless steel, so it´s not so shiny as chrome. It´s more like 4-2-1 system than 4-1. There is wall in the collector pipe. Header pipe diameter could be bigger but I think it performs good enough for the street bike. For the price it cost it´s very good quality.

I bought Delkevic Bandit 1200 downpipes to my GSX 1100 EFE. Exhaust flange bolt holes needs to grind wider, made adapters to spigots and grind oil pan cooling ribs down a little.

I have FBG plates in my EFE and the clutch lever free play is bigger when the engine is hot. Still the clutch is working properly. It not slip and neutral is easy to find. As Arttu wrote, the straightness off the steel plates is important. Last year I get my EFE clutch steel plates level grind and after that the clutch has worked perfectly, except that bigger lever free play when the engine is hot. Even the new oem steel plates can have small (0.01mm - 0.05mm) high spots.

If you want a crispier throttle response, you should make the plenum volume smaller. Mikuni HSR carbs are far more better than S&S. S&S carbas are made for Harley Parkinsons

Fixed, thanks!

Comp. ratio x boost (bar) + Comp. ratio < 16 and you are on safe side For example 10.5 x 0.5 + 10.5 = 15,75 I have in my supercharged EFE 11 x 0,5 + 11 = 16,5 No detonation and good torque

How "quick" is your intake air temp. sensor? and is there intake air temp correction? If the iat sensor is slow and it warms up when the boost is up, the iat correction leans the mixture. Change the iat sensor to quicker or disable the iat correction (if there is).
