2/1 Trevor Bovard w/ two mod F8 Firecats, one Rev 830 big bore.First F8 was a clone of the sled Trevor brought earlier, this one was a bit higher in midrange tq and hp, a bit less top end hp, needed totally different Boondecoker settings. Second F8 gave us fits, huge fuel flow from 7200 on up, even -99 at 7200 couldnt cure it, ECU from first sled and Boondocker from first sled didnt help so quit this one [turns out the sled owner had EGV cables installed backwards so the ecu went into trouble mode]. The 830 has been very fast in the field, but dyno airflow cfm and hp numbers were low, not much better than stock. Going back to autopsy [maybe bad reeds, mousenest in muffler, etc?], will be back after issues dealt with. Also had a HTG proX 900 twin, 180hp but weeping coolant into mag combustion chamber, Dan and Dan are rectifying at their shop near the dyno.
2/2 Pete Nixon, F7.cancelled
2/5 Chris taking another crack at his Cudney 830.cancelled
2/6 Justin Fuller (took over Bender turbo business as Full Power Performance) with ABay/ Goose Bay madman Stanley Parker’s RX1 with new bigger turbo shooting for 400? 410 with only 19psi boost thanks to Justin’s cylinder head tweaks… PM tentative Dan and Dan with their formerly vibrating Storm Stroker 1000 improver.cancelled
2/7 Jeff Sherlock Firecat F9 stroker.864cc, made 182 HP with single pipe and stock muffler, 193 HP with D&D monster twins.
2/8 Aaron Luczak F1000 all D&D stuff, tuning Boondocker in AM stock head, trailport easy tune to 200hp, tweaked midrange to get rid of bog? no lean midrange on this one.
early pm, two 518ers with lake racer MachZ’s microphones off HP secret, second MachZ had Boondocker troubles with N2O system, will be back again maybe with 4 injector Boondocker? Late PM Mike Gross one more time with 1107 cat, this time with shortened Jaws pipes to reduce torque but revs higher, HP higher than before. Heading for Lanzis.
2/9 am F7 trail sled for fuel pressure tuning (early ECU with key and BMP mod stock pipe). trail porting, 03ecu only needed fuel pressure restrictor to drop fuel flow from 110 lb/hr to 98 lb/hr to make 155hp on pump gas.
2/12 nothing scheduled this week. Time to post some more info.
2/13 early PM, Trevor Bovard with the troblesome F8 once more, plus an XC800 w/ SLP head and twin pipes. Late PM Dan and Dan with the 1000 storm stroker. Trevor had trouble again–this time flatlined at 165ish hp, then hp dropped, leakdown high on both cylinders, coolant getting into engine will be back one more time…but the SLP twin pipes and head on Rick Ws stock XC800 made 160+ HP…
2/15 Boyeson Reeds another test with stock MachZ to test reed cages/ wings once more, a new sled Joe bought has broken in now, stock for sure. Jim Cooper coming to fine tune and monitor/ control engine.cancelled
2/17 am Glenn Hall w/ D&D F1000 w/ 1200 big bore for a DTR tune/ number–this one ripped the connector bolts out of D&D’s dyno driveshaft yesterday, so they want to finish tuneup here Sat AM (and try to rip my connector bolts out).160 lb.ft with single pipe and twin pipes, 226 and 235hp respectively and the molecules in my grade 8 bolts are still holding hands. Will post these dyno sheets this week.
2/20 Justin’s and Jonas’ F7 and MXZ800 trial stockers Justin’s F757 w/ BMP mod stock single with no tuning made 160 (very lean 04 ecu) added wet N2O tuned N2O jets to add 40hp…Jonas’ MXZ800 made 138 stock added 4 hp to 142 with Dynoport single then added 32 hp with a safely tuned wet N2O system. In PM Greedy twins Tripod Dan and Danno with their IS1000 Storm, looking for consistant fuel flow and more HP.went back to stock motor mounts, removed reed spacers so filters weren’t hitting frame, fuel flow was 50% better, but pto 48 megatron had egt temp way off from the other two, 200 degrees higher stayed that way even with powerjets cranked wide open the other two at 1/2 turn…danno switched pro and middle carb to see if hot egt follows the carb and now with all powerjets at 1/2 turn egts are identical and HP is higher…needed to jockey the dial indicated needles to create identical EGTs with identical powerjet settings now perfect, tried tighter stingers not happy, cranked another 2 degrees of timing added two more HP now solid 256-257hp quite good for an old Storm 1000.
2/21 Schools closed, will have my 8 yr old son to watch over. I’ll take him to lunch at McDonalds, probably the only father and son there that get a senior coffee and a happy meal.
2/22 Scott coming from MI to dial in a SLP ported Fusion w/ Boondocker, has SLP single and a set of CS twins to test, wants to compare with HTG big bore Fusion tested here considering the value of HP added by bigbore for possible summer project. Then Scott will squirt some N2O into the engine w/ Boondocker N2O system.with SLP single and reflashed ecu with all zeros on Boondocker made 115 lbft and 160hp at 7300, added 28 hp with two five hole N2O nozzles HP slid up a few hundred revs which will make for easy clutching.
2/24 going down to Loon Lake Sat AM for some hardpack lake running with my HTG1000. Red edge with chewed up mudflap (I have the old Firecat track off of HTG Rob’s 1200 edge with skidframe extended by HTG Joe and those 2″ long carbide picks ate my new mudflap) and goofy 600 decals that I just havent had time to replace yet. newsflash Dan and Dan had Tom Chapel of Visual Impact Graphics in Byron NY 585-545-7118 suprise me with blue/ white 1000 numbers that perfectly match shape/ design of the old ugly yellow 600 numbers, so I wont be accused of trying to have fun picking on 600 twin sleds. Now I can enter the three cylinder electric start reverse carbide pick class legally… Loon Lake is about an hour South of Rochester on rt 390.
2/25 Vince came from Albany area Sunday to find out what’s wrong with his ProX 800/ 870 big bore, built by a well known sled engine modifier, no revswith normal clutch weights… with SLP twin pipes, made about 112hp at 6600 rpm, then hp dropped. Airflow CFM was low compared to other ProX800s. Tried different CDI, no change, good leakdown, crank indexing was fine, ex valves opening for sure…??..I convinced Vince to leave the sled on the dyno and come back Monday with a box of parts to swap on the sled; carbs, reeds, coils, stator, exhaust, came back monday spent most of the day changing everything on the outside of the engine, no difference in HP, final change was to take off the twin pipes and install stock single pipe, HP dropped to 94 and we were out of parts to try. Vince has the sled home, pulling the cylinders/ head/ pistons to have someone else examine to see why airflow is so low, and HP drops after 6600 (airflow flatlines from 6500 to 8000).
2/26 Full Power Justin Fuller with another RX1 stage 4, once again shooting for 400 plus. moved to 3/1 to allow me to create driveshaft guard for direct drive on dyno.
2/26 PM or 3/1 Tentative Joe From Boyeson wants to basline his own bone stock for sure MachZ then install Rad valves only to see airflow change, HP change over stock reeds. Need Jim Cooper here to do that correctly.
no test scheduled–
