Title: Pat's 58 with Kompressor! Post by: roland on October 09, 2009, 19:14:24 pm So Pat fired his 1776 with Kompressor & injection last friday for the 1st time! He went to the rolling dyno this week and scored a 185hp and a big oomph factor it seems.. not bad for a tiny 1776...
Yvre is the master of the electronic stuff (don't ask Pat to turn a computer on or off, he'll scream at you :) ) He's been working with Pat to get the electronic injection working. This week he put the rest of the car together (lights, fenders, removing the tape from those lexans windows...), test fitting everything. So they are on their way right now to Bitburg to see how it's all going to go. If some of you want to join ;) I'll be going on sunday (unless it rains or everything is blown up tomorrow) (http://blogsimages.skynet.be/images_v2/000/002/114/20091009/dyn006_original_822_487_jpeg_2114_f37e22c07730cb76b57740ac3dac4916.jpg) (http://blogsimages.skynet.be/images_v2/000/002/114/20091009/dyn006_original_822_469_jpeg_2114_b084d6be658095571f4ab76d3c9e7670.jpg) (http://blogsimages.skynet.be/images_v2/000/002/114/20091009/dyn006_original_822_411_jpeg_2114_210e1d896c7bbb2222c4f909b97871c1.jpg) Title: Re: Pat's 58 with Kompressor!

Post by: yvre on October 12, 2009, 21:54:18 pm Not so well saturday, and quite badly on sunday.
Let me get a beer so I can tell the whole story... (runs to the fridge and opens a cold one). A few years ago Pat managed to score a free Eaton compressor from a 2.3L Merc Kompressor. He assembled a 2.1L engine from parts he had laying around, slapped a Weber 50 DCOE on it and installed it in the muppet. The car made 210 hp on the dyno, but was barely driveable because of the carb, and the belt system was clearly no up to scratch. 3 years ago, he began building his own drag car (seeing that Vanessa drives the 62 all the time now). That's when I talked him into putting a Megasquirt injection on it (I had always wanted to do one, and the price was right to him ;D ), so that's how the 'joint venture' started. We bought the ECU (MS1 Extra from Philip Ringwood in the UK), I bought the injectors, pump, etc at a local Mercedes dealer (with employee discount) and read and read and then read some more while he assembled the engine with some more leftover parts. Engine specs are: 69 stock non-counterweighted crank x 90.5 Mahle cylinders Stock rods ( ::) ) 40x35 041 heads Engle 110 cam 7.3:1 CR Homemade pulleys with an industrial belt 009 distributor with 24° max advance (we decided to start with fuel only, as recommended) As it was in 2007: (http://i19.photobucket.com/albums/b166/yvre/P1030271.jpg) Title: Re: Pat's 58 with Kompressor! Post by: yvre on October 12, 2009, 22:19:49 pm Fast forward to 4 weeks ago.
Pat calls me to tell me he wants to get the car running for the last session of the year at Bitburg!!! There are still a zillion things to do on the car, and the engine has never even started (it was jut run in with carbs 2 years ago). So we spend a few late nights to finish the last details (you know, like fuel system, complete ECU wiring, etc...), and he takes an appointment at the dyno this thursday (08 oct). So we need to get the car running for this date. On thursday, the car starts and we manage to get a pretty good idle. But unfortunately he filled the tank with E85 instead of super unleaded fuel (dunno why), so it needs to be way richer that what the injectors are capable of (we reach 50% duty cycle just revving it...). And the car dies as soon as we open the throttle. On friday night, we change the fuel and start it again. I had prepared something that vaguely looked like a fuel map on basis of some maps I found online for turbocharged flat 4 engines. I also modified the Acceleration Enrichment values, and this time the car responds well to throttle changes. We play with the idle for a while, I grab the LM1, the laptop, and we hop in the car for a few runs around the block (without windows or lights, of course). I was hoping to do a bit of tuning, but the car is so cramped (or maybe I'm too big ::) ) that I only managed to check the AFR on the LM-1. We were running rich all the time so that was good. First impressions: the car is very light, very responsive, and it's very cold outside!!! This is my butt you actually see through the rear window in this picture: (http://blogsimages.skynet.be/images_v2/000/002/114/20091009/dyn006_original_822_411_jpeg_2114_210e1d896c7bbb2222c4f909b97871c1.jpg) Title: Re: Pat's 58 with Kompressor! Post by: yvre on October 12, 2009, 22:32:46 pm Between friday night and thursday, we spend some more late nights working on the car, but we are ready for the the dyno session on time!
We make a total of 5 or 6 runs (can't remember, I'm tired...), playing with the AFRs and the ignition advance. We start at 145hp (way too rich and 21° total advance), and finish the afternoon at 185hp and 270 Nm torque (12.5 AFR, 25° total advance and 12 psi boost). I have the pics of the dyno graphs on my camera but I need to find my camera first! The torque curve is super flat! (http://photos-c.ak.fbcdn.net/hphotos-ak-snc1/hs245.snc1/9216_151882171649_122198171649_3183138_5043076_n.jpg) Only problem we have is that the engine will not rev past 5,000/5,500 rpms. We have no rev limit set on the ECU, so we think it must be spark blowout???? Title: Re: Pat's 58 with Kompressor! Post by: yvre on October 12, 2009, 22:48:54 pm Anyway, we are ready for Bitburg so we met our objective.
Due to the rain (California deaming...), we only manage 2 passes on saturday. But with the 3.000-5.000 rpm powerband and the small tires (they're 24in currently - switching to 26in this winter), the car maxes out at the 1/8th mile mark :o With the car coasting to the end, the times are nothing to be proud of (best of 13.4 I believe). But most important, the car goes super straight and Pat feels confident with it (would be a shame at those speeds ;D ) On saturday night, we meet a nice german gentleman who is also very much into Megasquirt, and we try to sort out a few problems we still have (no Lambda reading on Megasquirt, different code versions between the ECU and the tuning software, etc...). But while doing so, we manage to screw the base settings, and it takes us 2 passes on sunday morning to correct this. On the 3rd pass, the compressor pulley bolts shear during the 3rd gear burnout, so that's the end of our racing. It starts to rain again anyway, so we leave the place, eat our 3rd Burger King of the Week-End and head home. Plans for the winter: - redo compressor pulley - fine tune fuel map - switch to wasted spark ignition - add water injection to reduce intake temps - pass the 200hp mark (hopefully) and do some real 1/4 mile times No I'm off to bed - I really need some sleep!!! Title: Re: Pat's 58 with Kompressor! Post by: Ole on October 13, 2009, 08:26:58 am Hi Yvre,
thanks for the report, very informative and fun to read! 8) I remember when Nico tried this engine in the Muppet, he looked really scared after the first pass... ;) :D When he changed back to a N/A engine I was thinking they gave up too early. It's good to see people working on a really unusual setup. It sure will need a lot of work to run properly, but I think it's something very special to do it in a way nobody has done before. Keep up the good work! Saludos, Ole Title: Re: Pat's 58 with Kompressor! Post by: Udo on October 13, 2009, 09:24:10 am Anyway, we are ready for Bitburg so we met our objective.

Post by: jamiep_jamiep on October 13, 2009, 10:02:59 am Great report on the weekend yvre, and nice shot of your butt too ;)
I have had more than a few disheartening weekends like that, but each time I get a setback the car has got a little better. And the times its run with the shut downs show the potential Pat! It looks a great bug and can't wait to see it after a winters work, sure its going to kick ass next year. Please keep us updated! Title: Re: Pat's 58 with Kompressor!

What's the weight of the car no driver? Maybe you should try a STOCK gearing with that amount of torque,or just borrow Dam's gearbox ;) ;). There's still 1 event coming to test the car,31oct go to AVONPARK raceway ;D ;D Well done to Pat's team Steve Title: Re: Pat's 58 with Kompressor!

(http://i153.photobucket.com/albums/s207/Frallan2/tullinge_4_b.jpg) ...and this rear engined dragster will run with a Supercharger, soon to be on top of it too. Same engine and setup but with a Autorotor and Hilborn. Therefore I am following this thread with extra interest. I really like it! Well done!
