wazzy250 167 Posted June 14, 2014 Nice progress.Will u b using the knock sensors in ur data jason or just there to plug the holes. 1 slydog reacted to this Share this post Link to post Share on other sites
TF_250 398 Posted June 14, 2014 Yes wazz the knock will be used for tuning and datalogged as well. Share this post Link to post Share on other sites
TF_250 398 Posted July 5, 2014 Sent the engine to have the cams setup and piston to valve checked and that's were it stoped no piston to valve on the intake side bloody ford heaps on the exhaust though and you can see by the pics why!! Compare the piston and rod with a 250 & ACL race series flat top VS Stock n/a FG I was so close it was only meters away from the dyno!! now I have lifted the head which i didn't was to do. Also these things run a 0.016" thick head gasket or really a steel shim, rod bolts apart from being metric are the same as 250 as well. Now i have to get all the intake flycuts don in the pistons and then can set the cams were the tuner wants for maximum vct use. 1 Outback Jack reacted to this Share this post Link to post Share on other sites
wazzy250 167 Posted July 5, 2014 Bummer jase. Big learning curve. Remember good things come to those who wait 1 TF_250 reacted to this Share this post Link to post Share on other sites
PRO250 1,506 Posted July 6, 2014 Sucks mate soooooooooo closeso non standed pistons are causeing that issue? or all the piston have no cutout for the intake valves? Share this post Link to post Share on other sites
robbie 901 Posted July 6, 2014 Finally found this build Jase, dont know how the heck I missed it. Anyway, thumbs up to ya.. your work is top notch man! Cant wait to see more When she's all sorted, this little roadblock with the pv clearance will be a forgotten memory 1 TF_250 reacted to this Share this post Link to post Share on other sites
TF_250 398 Posted July 6, 2014 Sucks mate soooooooooo close so non standed pistons are causeing that issue? or all the piston have no cutout for the intake valves? Mate those are std factory ford pistons they have no intake cutouts, they hopefully will be the piston I will continue with. Share this post Link to post Share on other sites
PRO250 1,506 Posted July 7, 2014 Fair enough mate i did not knowdo the turbo engines still run the same pistons? you have to bear with me i know little to nothing about the BA FG engines apart form lifting the topends can be a pain so much shit and not enough small hands Share this post Link to post Share on other sites
TF_250 398 Posted July 7, 2014 It's all god mate I'm learning as I go as well from what I can gather they are all the same motor, the turbo has a dish piston and 8.8:1 comp, the n/a which I have has a dome piston with 10.3:1 comp and the gas must have a bigger dome and 12.0:1 comp. the tuboo piston has the cuts in the exhaust only as well. I'm hoping there is enough piston to cut the intake side as well will the hopefully getting this sorted this week. 1 slydog reacted to this Share this post Link to post Share on other sites
TF_250 398 Posted August 19, 2014 Man been a while on this nothing goes to plan and nothing is done in a hurry either!! Piston to valve done, the piston was not really thick enough to get to the vct position that we really wanted but we will still have a fair amount to play with as is now. hopefully going back together soon!! 2 Mixalis and Outback Jack reacted to this Share this post Link to post Share on other sites
slydog 7,873 Posted August 19, 2014 Didn't want to "buy" some pistons Jase or hoping/planning not having to rev this 1 to high ? Getting closer Share this post Link to post Share on other sites
TF_250 398 Posted August 20, 2014 Nah Rob I didn't even want/budget to pull the head off now the thing is completely apart. If I do pistons they would be full custom then I may as well to rods then crank blah blah blah the bottom end is them same as the old xflow and it made 340hp so for now this will do. But who knows what the future will hold!! 1 slydog reacted to this Share this post Link to post Share on other sites
wagoon 2,429 Posted August 20, 2014 Ah the joys of setup. Glad your getting on top of it jason, looks like it shouldnt be to long before your running again. Share this post Link to post Share on other sites

slydog 7,873 Posted September 4, 2014 LOL sounds like it's got a resonate frequency like a F1 engine. You'll be racing it this year by the sounds of that. Good luck bud Share this post Link to post Share on other sites
ando76 4,354 Posted September 4, 2014 Good to see it running - be keen to see final numbers. Share this post Link to post Share on other sites
TF_250 398 Posted September 4, 2014 Xflow - 345hp @ 6100 333ftlb @ 4700 FG - 355hp @ 6050 342ftlb @ 4500 same dyno, same fuel brand, same manifold, same exhaust, same tuner, 3 years apart!! So thats a stock FG DOHC head port, chamber, valve angles etc which is different to BA DOHC also we love vct saw one simple change at 5000 to the exhaust cam and gained 20hp!!! the cams have 60 degrees of movement and we are using all of that through the rev range. Should be back out racing in the next few weeks if all goes well. 8 Thom, Mixalis, PRO250 and 5 others reacted to this Share this post Link to post Share on other sites
ando76 4,354 Posted September 4, 2014 Well that is impressive for a stock port motor and shows how far port design and variable cam technology has come. 10hp & 9ftlb gain from a head that was designed in the 80's (granted it was heavily ported) to one from what say 2010. Shows how good the original design was. TBH Jason I was hoping to be proved wrong by a bigger margin than that, none the less a great achievement by you to get it in the car and running and such a neat conversion as always. Be interested to see if there is ET gain. Share this post Link to post Share on other sites
