 Specializing in Off-Road Applications.

 Miller Fuel Injection (MFI) is in business to put Bosch CIS fuel injection on air cooled VW motors in on-road and off-road vehicles.

Why? Injected motors always pull when the throttle is opened! No matter what rpm, grade, bump or temperature, injection delivers the correct fuel for the air the motor is using. Instant pull from idle makes even stock 1600 motors pleasureable to drive, and large and modified motors create more usable HP over wider rev bands than carbs. Now your motor can grunt AND scream.

Air cooled VW's are worse than most engines to carburate, with widely spread ports, lack of cooling water and left-left firing order. One, two or four barrel systems all have problems, including maintenance complexity and drivability, compared to injection.

Bosch CIS is port fuel injection without digital computers and programming. The airflow meter is an analog mechanical "computer", creating 4 fuel streams proportional to the measure airflow and warmup conditions.

For unique installations like yours, tuning is a set and forget process. If space is available (sorry, beetles with hoods), the installation should be a mechanical process, requiring no computer skill.

Blower Project Pics from 04 Feb. 2006!



Early Blower Porject Pic:



NHRA style BLOWN motorheads, my T3 cooled / T1 long block / port injected with Eaton supercharger idea is getting closer to reality. I think smaller motors with lots of supercharged boost and water injection for knock control will be the best $/hp and excellent throttle response, for tube frame cars.

Latest 2.0 SOHC Ford (Pinto) kit is bolt on for engines using standard size spark distributor bodies.

I'm under the wing of sandrail magazine on the web, my site is no longer stand-alone. I know you found me if you are reading this, please bookmark this or their front page.

I am deciding to ship kits without the following items. I cannot devote the time to find enough to maintain and grow the business, or I provide little to no value by handling them. They are all in unmodified condition, and if used parts, testing is trivial and shows most are usable. I can test pieces if they are shipped to me. Here is the short list, I will put much more info in the owner's manual section, formerly called Replacement parts. Unmodifed air/fuel meter is latest deletion, prices are dropping again.

Not included in kits:
Bosch: (from CIS equipped car): Air / fuel meter from pre’80 car (except 180 hp kits), fuel pump, warmup regulator, cylinder injector (except 180 hp kits), thermotime switch for cold starts.

Filters: Air, fuel prefilter, fuel high pressure filter.

OEM: VW rabbit lower half of plastic airbox / air filter housing, aiflow duct and rubber boot to airmeter, Audi/VW Fox fuel sumps (some applications), Volvo 242 air meter mount castings (for some remote air filter applications).

This is a very small percentage of the value and part numbers shipped in the kit, and prices will reflect this change, some customers have been requesting this. Feedback? Let me (gmiller@pacifier.com) know. My website goals are: fast loading, lots of pix if you want them, no BS.

Old News (for some):
The SandJet457 story continues, it is now at home on the Sandrail.com corporate vehicle, and Mike Kief's 2110 continues to grow and stretch. It still has stock size intake ports, and makes 107hp at the rear wheels on 92 octane with killer 2200rpm torque. I drove some of the chassis dyno runs myself, and the video is on my demo video (now free for the asking). I love to shake the walls (used to design stereo gear) with this open stinger video run, flat out from 1000 rpm! The machine has some dune time (we run in summer, not New Years).

Previously, Mike Kief of Sandrail.com has been upgraded to aluminum runners and "butterfly" throttle porting(kit 19), and has a nice combination of wheelie power and easy drivability. The graphs to show 30% additional top end power increase due to the Intake upgrades, another graph shows 40-50% hp increase ACROSS THE BOARD over dual Kadrons, but does not tell of the drivability improvements.

More T4's have come to life, one guy drove less than 50 feet before remarking how nice it was! One T4 bus was converted in 32 total clock hours.

I've finished design and pricing on the 2.0 Pinto intake conversion combined with my hi flow fuel kit, see Prices and Services (http://www.sandrailmag.com/millerfi/kits.html). Check out the Prices and Services. In impartial terms, Doug's Ford rail JUST ROCKS, with a big cam. This is the first real 7000rpm sandrail I've been in, quiet, smooth and VERY fast.

Mark Falls (Portland, Or) (etherorb@hotmail.com) is buiding a sweet '71 Bay window bus with compact upright intake set for cramped top shroud 2L T4 installations with DTM shroud, and custom thermostat flaps on fan intake. Still new, he's driven it 6 miles sorting out ignition problems.

Mark Fitzsimons (Portland, Or) is ditching his dual 40's on his 1.8 T4 Bus for MFI CIS. They make good doorstops IMHO. Mark has driven it, and it runs supernice. I had to keep asking if it was still idling, it was.

Mike Sill (MSill30144@cs.com) and I have fired his Beetle based T1 powered semi-unlimited class desert race car, similar to my Rock-It installation. This car is 10" wider and 14" longer than stock, about 15" clearance and 12" travel. Very exciting project, 2165cc T1 motor sounds very crisp.

Dr. Brian Johnson's (horse@pacifier.com) '65 3door combi with 2L T1 has about 200 miles on the conversion, the bus is still being detailed. 2007cc T1 creates excellent grunt.

Ross Dykes from Bay Area,Ca. (rdykes@scu.edu) has just fired his 1.7L T4 bus converted to MFI. He's climbing hills in 4th he could not get up with stock dual carbs. Unsolicted testamonial: "There is plenty of low end torque, so there isn't as much of a need to rev it up as there used to be anyway. My roommates don't believe that there's only a 1.7L under the hood, the performance is so much better than the carb setup." Ask him what he really thinks.

Gary Mondshine from Detroit (mondshine@mediaone.net) has finished his 181 Thing. Unsolicted testamonial: "I drove the Thing for a short while yesterday and quite a while today. Wow! It runs great. The car has great power right off idle. Not that I'm an engine lugger, but the car can easily pull away from 15 - 20 mph in top gear. This is a tremendous improvement over any intake I have ever had on this car." Mondshine has installed a front fuel sump and pump., and using steel runners on his stock 1600. Meter install in rr fender. Finished install, with unique (?) air duct into throttle. Ok, super clean even with the shop vac hose.. I plan to leverage his work for future 181 installs.

Ed Villela from New Jersey has finished converting his 1700 cammed 914 Nice website, Ed to MFI. I had done a rough install here (see "fitting it in"), Ed has fleshed out the details. So far, he's won a first place in an autocross (about 2 seconds faster than previous comparisons to competitors), and has driven FAST and gotten 27 MPG in the same weekend. Hot restarts are much better than earlier, ask him what he thinks.

Robert Piacentini (sculptr@pacifier.com) has a 1776 T1 in a '65 bus, MFI injected of course. Flat out 3rd gear uphill and a conversation can still be carried on, and the machine moves right along. Since original install, upgrading to aluminum intake runners turned this short (69mm) stroke T1 into a screamer. Very fun to drive.

Tom Pagel (tpagel@worldaccessnet.com) in Vancouver, Wa has driven the his turbo VW1800 water pumper rail, sidewinder chassis with my 180 hp fuel setup, with dual fuel pumps. "I can climb any dune at North Bend with ease. What a feeling of power ! "10 psi boost is leading to some detonation with 100 octane, no intercooler with small Subaru turbo. This is advanced stuff, but Tom's a VW tech. He is still sorting out timing and other engine details.

Scott Fraser (kn6f@dolphinsci.com) has a mutant CIS setup I helped on, and just got to drive. 2L T4 Runs sweet with tallish gears.

My 1500c SOHC water pumper Fiat installation is a joy injected, and this is the genesis of the whole idea. 10 years ago I had the idea to inject it, it was sort of by accident I tried CIS on my VW buggy. I get 30 mpg, I'm getting about 3 more mpg than 32/36 weber, which had less power (UNTESTED CLAIM) and way less fun to drive. This is pretty universal hardware, after you figure out the engineering behind it.
