ando76 4,354 Posted April 4, 2016 The thing the dizzy is attached to is a Hilborn style mechanical fuel injection pump. These pumps are usually belt driven so I'd say there is a belt driving the pump and the dizzy shafted has been machined onto the back of the pump drive. The injection trumpets and throttle bodies are from RHD engineering by the looks. I was looking at these recently but went with the Jenvey units. The RHD units are Tiawanese made but the quality is up there. The company is Aus based. They are competively priced and the trumpet lengths are adjustable for 'harmonic tuning'. It was a real toss up for me but I went with the U.K. made Jenvey units as I liked their trumpet design and injector position better than the RHD units. Plus competition systems did me a great price on their units and the valve back to butterfly distance was perfect. The video of that brings engine running is just pure porn and very inspiring. 3 Mixalis, NZXD and matt_lamb_160 reacted to this Share this post Link to post Share on other sites

ando76 4,354 Posted April 5, 2016 Impressive numbers for sure but I'm calling a Hollwood run. Why? Look at the afr's. That's not sustainable in the real world. Never the less that is one impressive engine. Brinks build some really cool stuff and JB's dyno does not lie. Torque is reasonable as well which is not real common in those multi valve things. I've seen 300+ HP Barras get dusts by 230-250 HP crossflows many times in the dirt. This engine is a thing of beauty tho. Some awesome engineering and very inspiring.

TF_250 398 Posted April 5, 2016 LOL Hollywood, those afr's look spot on. 5000 13 .885la 5500 13.25 .90la 6000 13 .885la 6500 12.5 .85la 7000 13.5 .92la I run mine in the same range, even up to .94 every time I roll into the water box and I'm on petrol I'd run more on alcohol. My Crossflow wouldn't go that high but then again you need 10 degrees more timing in a Crossflow then a Barra .88 under load is to rich for these engines mph loss is a result. Barra to the front. Crossflow to the dump!!!! 2 slydog and 78xcgxl reacted to this Share this post Link to post Share on other sites

ando76 4,354 Posted April 6, 2016 That looks like afr petrol scale to me Jason and if so, I and a lot of other tuners would not be comfortable running engines that lean in the real world. But then again I tune engines for endurance motor sport, not 10-12 seconds at a time, so what would I know. Funny thing is the dip into the rich starts making power right at the top and then it loses power as it goes lean again. Like I said the guys at Brinks build some great stuff and I'm not shitting on the engine. It would be making every bit of 500 and probably more. It is not uncommon when tuning to go for a Hollywood run and then back the tune off. That's just my opinion on the run. Be good to see you step yours up to try and beat Ken. Till then we will just have to put up with the old pushrod dinosaurs being the fastest aspirated corty. Mine is still a way off thanks to the little change in direction but I'm hopeful that it will out there punching some decent numbers by the end of the year. 3 Outback Jack, slydog and Mixalis reacted to this Share this post Link to post Share on other sites
TF_250 398 Posted April 6, 2016 LOL always something Tony, this engine should run a high 8 sec pass and when it does it will be yeah but you can't beat Ken!! love it. totally different racing programs. No one will beat Ken, NO ONE!! period..... not even a hammer-wielding god engine from FNQld!!! 2 Campo and slydog reacted to this Share this post Link to post Share on other sites
ando76 4,354 Posted April 6, 2016 Just don't like it when someone bags crossflows. Rob passed the comment on Ken's - u replied in the tone that one day u might catch him. I said good have a go. I will be. Ken is the bench mark for sure and no one is unbeatable. No one. It's just time, effort and money and I have all that. Oh and I seem to remember a non hammer fielding FNQ car beating Ken once so I'd be careful. I never once bagged that ba engine or the builders. I just called what I saw from a tuners perspective, nothing more. It's a strong, well built engine and a great conversion. 2 matt_lamb_160 and Outback Jack reacted to this Share this post Link to post Share on other sites
matt_lamb_160 252 Posted May 20, 2016 That thing is awesome. I also want to see a picture of the speedway car with the cam driven dizzy and all the silicone. Loving the competitiveness coming out here too. Share this post Link to post Share on other sites
