Re: Engine/ECU Upgrades
No problem Jay...
I already installed the ViPec ECU. Yes, it really does have a real boost in performance. I opted for the unlocked version as I just love to tinker!!!
One great point to a fully accessible ECU was that it made very appearant the problems that were able to be repaired at no cost to myself other than adjusting this or that. Such as notching out the firewall and throttle pedal stop to allow the intake butterflies to open from a very near true 0 to 100%. I basically have been running about 80% movement from day one and its just one of them things that you never think to check!! I had a range of probably 5 to 85 %.
I'm also running a live AFR gauge and it interfaces with the ECU to allow an on the fly auto tune. That feature alone makes it worth its value of $2,800.00. Being the test guinea pig for all you folks, I get the added luxury of some real quality time with Mark Queen in development of these products, maps, etc. Mark turns out to be a young dude with a sharp head on his shoulders and a skill set on par with most lifelong performance guru's. He's that good.
Always remember my famous quote(I made it up myself even): "EPA compliant means from the factory with asthma!!" With just the ECU and a totally retarded BiG Gun refit of their pipe and K & N air filters bolted straight to the throttle bodies, We know for sure we ran 58 MPH (we ain't figured the GPS out yet, LOL, just happened to be lookin) and the best time for the Jagged X car was 62 mph we heard!! Mark also figured out we need some clutch reworking as well. He was adamant we should be able to get another couple hundered RPM over 8200 or so with clutch work.
The engine is a bored 798cc non-stroked version. It's actually Marks first naturally aspirated as he normally builds turboe'd. He's done a valve job, port and polish and reconfiguration of the combustion chamber. The block is sleeved and the compression is raised. I ordered a mildly modded engine because durability is as important as short run pucker factor. Vegas to Reno is 1000 miles. I don't want an engine that needs rebuilt several times a season!! Mark rebuilt an engine I found that neede some crank rebuilding and lower end repair. The crank repair came with better oil ports and Frankly Mark said it turned out better than a new one.
We're expecting at least 100 hp and possibly up to 115hp. We'll see!! That said, we were passing confidently before we overheated which I chalk up to lack of proper testing on the ECU before start time. Gotta rememberm lot's of built engines and the ECU alone made me feel on par to everything out there. Even the Arctic Cat!!! There's alot of hammer on the gas, get off the gas, hammer on let off, over and over, and having the ability to richen the let off side should take care of that. We just hadn't planned on that with the two hours set up we had!! Pull your foot outa a full throttle to a no or little throttle and you get a repeated lean condition, hence an overheat!! However, I've only just acquired a program that should fairly acuratelygive a HP, but it has yet to be dynoe'd. I'll get it done after the engine swap......
As for the motor I should be returning to Lake Havasu next weekend and installing it and testing. I was getting about 9 mph I figure, Mike may have a better idea for sure.
In all honesty, I woked with about three hours sleep for two weeks leading up to Parker, driving 22 hours on 1.5 hours sleep, finishing the car in Lake Havasu with tech inspection happening just as they were starting to tear it down for the day. I wasn't mentally ready to race that Saturday, and the car needed some testing time still. But as they say, "It is what it is!!" there's always some drama leading up to the race, but this really was over the top pushing it.
I've since got Tire Balls as sponsors and am slowly tightening up the loose ends!! Next time, O.L.D. Racing will, I repeat WILL, really turn some heads!!
