General success: 17 podium places in Latvian championships during first five months of 2009. Half of them - gold. Plus two podiums outside Latvia.
Here is some cars I worked on:
Audi 20V n/a - my favorite field. Not because of successive engine, but even contrariwise: get 100hp/l is realy difficult. We have n/a 4wd class in our rally-sprint (similar to rally but shorter distance in special stages). And there is only two appropriate models: Audi 20V quattro or Subaru Impreza 2.5RS. About 6 Audis is tuned by me. Two using VEMS. Only one time have strange flywheel. Needs hall signal inverting (not safe solution - normally AudiTrigger can work with no Hall signal. If inverted - no)
Update champions of season 2008 in rally-sprint.
Mazda F 1.5liter. Turbo without any changes inside engine. 0.4bar boost at max torque and even 0.7bar @ high Rpm. Not great success in figures, but was pleasure to tune.
BMW with '99 M3 engine. It runs. But with simple 4 position VANOS control from misc outputs. 300Hp/300Nm.
Audi 16V n/a. 1847cc. Headworks. exhaust cam as intake. 160Hp 200Nm. Needs better exhaust. Upd: have better exhaust. ITBs in near future.
Upd: now 2L. Itbs from bike. tuned trumpet length. Gives very close to 200hp on 276cams. wait for race cams.
Kadett E c20xe. (my knock page object). 190Hp on stock cams. Custom intake manifold.
Volvo 740 turbo. 8V engine with some improvements like big intercooler and bigger turbo. Needs better exhaust manifold. OE is restrictive.
1.6L 8V VW crossflow. Successive ITBs project: wide powerband from 4500 up to 8500 and 100hp/l
Mithubishi Eclipse gen1. 2L turbo. 4WD. Hybrid turbo inside OE turbo housing. About 360Hp and 450Nm @1.5bar boost. Upd: 380/465. Streetable with pleasure. Fights for third place in our local drag-race. Problems with launch control. Updte: third in 2008 sesion. It is great success: both leaders had much larger budget.
Two Imprezas 2.5RS '99. Using 24-1. It will be interesting to see how engine improvements rise stock power to something over 200hp. Now ~160hp. Looks engine have big potential: short stroker, place for big valves etc.
update: with only exhaust system 20Hp gain with no any loose:
Mithubishi Galant 4g63 2L n/a. For same n/a 4WD class. OE optical sensor with 24&1 disc. Strange engine with huge intake ports and low power. 160hp. Optical wheel, idle stepper, OE coil pack.
Few Audi20VT. Stronger is using GT3076R ball bearing, with some modified engine internals such as rods, pistons, headwork. In 2008 little over 500Hp and 600Nm in relatively wide Rpm range. Audi trigger. 1.1.27 boost control strategy.
Upd 2009 new turbo allows 1000hp. Engine allows 9000rpm. Ethanol. Currently aprox >700nm/700hp and deep transmission problems. such a broken primary g-box shaft. BTW it runs with auditrigger. 1.1.27 and 1.1.44. 1.1.5x in near future.
Many others Audi20VT for rally-sprint and street with different or even no modifications.
Toyota 2L 16V for rally-cross. Engine sits in VW Golf3! 60-2 alpha-n. In 2008 small head. But with some cams, ITBs and other mods engine produces about 175hp and ~225Nm in middle of very usable powerband from 3000 to 6000Rpm. It is OK for our short tracks. Big head under construction.
Upd 2009 wide 16V head. Close to 13:1 CR. Feels REALLY good!!! Perfect powerband allows high control level in race track. 1.1.44
Kadett C with c20xe Deep modifications: headwork, custom made exhaust system, intake plenum with trumpets, special cams, pistons. allows very high torque about 250-260Nm. About 210Hp (was not target). Alpha-N. Good on 201m. 1.1.27
LADA VFTS replica. In 2008 ~165Hp@7000 175Nm from 1.6L. CR 10.5:1 now. Must be 12:1. ITBs Wasted spark. 60-2. Needs valve springs.
Upd. In 2009 180hp achieved! Migrate to ethanol. 1.0.73 1.1.54
M3 S14 Sport Evo! Engine sits in BMW 1800. Modified from all sides. 60-2, camsync, 4 coils. Alpha-N. ~300Hp
Upd. Improved intake during winter 08/09. My rpm record. max power between 7500...9000 with maximum 309hp@9000. 1.1.27 and 1.1.44
Toyota 3s-gte FWD Corolla! 36-1 no camsync. For rally-sprint. Target was good driveability. 1.1.27
Porsche 928 32Valver. COPs from Cayenne driven from stepper chip in pairs. 60-2, camsync. 8 injectors sequential. IM flap from misc1.
Upd: will be turbo may be :) 1.1.27
Jaguar Sovereign 4.2L '86 60-2. Target was achieve perfect driveability, idling, cranking. Mainly done! I use firmware with IAC reference position correction from IAT. Correction seems too small even at highest value.. 1.1.41
VW Golf2 1.6 16V For rallysprint. 60-2 in rear crank sealing flange (OE from newer Golfs) Active coilpack from Golf4. Self-made intake - trumpets, plenum, one throttle. ~11.5 CR on RON98. First 2009th race was on icy roads - so OE camshafts was used for flat torque. Anyway we get power ~150hp@ with flat, usable torque from 3000...7000rpms. First race for new engine - first place in class, and high place overall.
Upd summer camshafts allow achieve over 170hp with rpm limiter at only 7400. Four golds in four races!!! 1.1.47
Jaguar XJS V12 with two VEMS. will be alpha-N. ("both" engines runs!!!)
Upd 2009 downgrade to street camshafts and retune for speed-density. 1.1.44
BMW e36 with M5 L6 engine Drift car. works perfect. 1.1.44
BMW e30 with M50 and M3 ITBs High CR on stock camshafts. Ethanol. Drift car. 1.1.44
processing:
Toyota AE 86. GT25 bb turbo. Fully sequential on stock 24+1 VR sensors. Active COPs from VAG driven from stepper chip. For drift.
pre 2000 Imprezas Turbo. (one on the road)
Some Audi 20VT (as allways) :)
Corrado 16VT. relatively low cost project. Bottom from 2E with stock pistons. It gives CR 8:1. Intake manifold cut from Audi S2 3B engine. self made tubular exhaust manifold. Wasted spark, but fully sequential - camsync from modified stock dizzy. 60-2 in rear crankshaft oil seal flange. t3/t4 gives to late power for street use. Migrate to smaller turbo. My first car really running on 1.1.54 Thanks for development team!!!
Calibra turbo. Target over 500Hp. No any successive pull until now. Gearbox. Fuel pump etc.
Opel tigra c14xe turbo. (it runs Opel Kadett c20xe turbo (it runs)
BMW E30 with M50 with turbo. Wait for bigger injectors and other improvements.
Mitshubishi Galant with 4g63 turbo.
BMW E36 M50 3L turbo.
