Clevo120Y 815 Posted November 13, 2013 Starting this thread is a little premature but I'm too excited, I will start to flow test some heads in the next couple of days. A bloke come around today and dropped off some 4V closed chamber ex sprintcar cast heads and some manifolds, I will put up some pics when I get some more batteries for the camera but just for now imagine a holley strip dominator plumbed with direct port nitrous and also a tunnel ram with hidden direct port nitrous in the valley, very cool shit. 5 xdwagooon, Thom, gerg and 2 others reacted to this Share this post Link to post Share on other sites

Clevo120Y 815 Posted November 14, 2013 Well I have some pics of the gear at my place at the moment here for some testing, not that the nitrous has any affect on flow testing but it just gives me wood LOL. I want to keep these heads and tunnel ram for my Datto hahahaha. Also a Holley strip dominator with NOS 1 Outback Jack reacted to this Share this post Link to post Share on other sites

Clevo120Y 815 Posted November 15, 2013 Well I got some testing done today, the big girl pulled over 290cfm at 700 lift and 270cfm with the tunnel ram attached.

gerg 10,871 Posted November 16, 2013 That's why the Boss 302 could scream to 8,000 rpm... It had those big nostrils to suck through! Share this post Link to post Share on other sites
NZXD 2,328 Posted November 16, 2013 Those heads really take off after 400 lift. My alloy Windsor heads are a tad better to 450, but that is where it ends for me. 1 gerg reacted to this Share this post Link to post Share on other sites
Clevo120Y 815 Posted November 18, 2013 Tested some holley strip dominator manifolds today, they are shit hot I rekon. the long and short runners flow nearly the same as each other and they flow 280cfm on 290cfm head, that's pretty bloody good. One of the manifolds is a normal 4V runner and the direct port injected manifold has the runner floors filled, the filled floor manifold only flowed 5cfm less over 550 thou of lift, I would sacrifice that flow for the added port runner airspeed the filled floor would produce, plus it has NOS hahahahaha. 4 Outback Jack, slydog, gerg and 1 other reacted to this Share this post Link to post Share on other sites

Clevo120Y 815 Posted March 15, 2014 Just finished porting a TFC manifold for a burnout car, worked out real nice. I have to do a set of 2V heads for it as well so I will post up the results when I get to them. 3 Outback Jack, robbie and gerg reacted to this Share this post Link to post Share on other sites
robbie 901 Posted March 15, 2014 Nice port job on the TFC. 4V's rock out of the box with their intake flow results.. did you flow the exhausts too back in November? 1 Clevo120Y reacted to this Share this post Link to post Share on other sites
Clevo120Y 815 Posted March 15, 2014 Yes I did, I will post them up later on. Share this post Link to post Share on other sites

Clevo120Y 815 Posted March 16, 2014 HAHAHA just finishing off the rest of the jobs that I had already lined up mate, this bloke is 1 of the guys that I will be looking after his work just for fun, I tried to convince him to buy my tunnel ram by sending this pic of his engine while it was in my workshop, he called me all sorts of names but stuck with the TFC LOL 2 slydog and Outback Jack reacted to this Share this post Link to post Share on other sites
Hofiveo 47 Posted July 3, 2014 Hangin to see how the 2vs turn out. Share this post Link to post Share on other sites
ando76 4,354 Posted August 28, 2014 Any 2V flow results sean? Cam has my 2v's at the moment. They just getting a good seat cut and bowl job and some hardened seats for unleaded. I want to run the iron heads as the XA GS is a bit of a rare thing so I want the original look. Going to run a hydraulic of around 290/300 adv duration and Lift .536/.562. Keen to see if that will be enough lift for the flow potential. Its just a fun drive car so no flat tappet or roller - yet...... 1 gerg reacted to this Share this post Link to post Share on other sites
Clevo120Y 815 Posted August 29, 2014 I'm about to start a set of 2V's next week actually LOL. I have stock flow results so I will put them up later. These heads are just a tidy up as well for a burnout XF. Share this post Link to post Share on other sites
Hofiveo 47 Posted August 29, 2014 Be very interested to see how they turn out with clean up. Looking forward to seeing the numbers on the stock heads aswell. Be great to see some pics of how you go about cleaning up the 2vs when you get around to them. 1 Clevo120Y reacted to this Share this post Link to post Share on other sites

ando76 4,354 Posted August 29, 2014 Damn my shitters are open chamber - reckon the flow would be similar. Some not too bad low lift gains but then yuk. seems as if a bowl and seat job might help plus a slight increase in sectional area just past the short turn. I'm thinking that hydraulic I picked might be spot on. Keen to see what improvements you make Sean. Thanks for the flow figures - great stuff as usual. 1 Clevo120Y reacted to this Share this post Link to post Share on other sites
