CV1- 235 port
From twinturrbo406 on pz
Well guys, there has been much progress down here in Fl, and i apologize for the lengthy delay, but we've just completed the development work on the new 235cc Intake Port for the CV-1's. This port will be the new entry level port for the as cast CV-1 head. It uses a 2.125 valve, which can be upgraded to a 2.150. We do not have results for that, but will soon. The port shows good mid-lift flow production and has a very smooth sound to it on the bench. The velocity is 300fps+ and the vacuum scale is very stable at all lift points and shows no sign of tumble or eratic flow. The current CV-1 Single 4 Intake Manifold is being retooled to house this new port shape. We are very close to finishing the shortblock of a 428 stock block build to dyno test the CV-235 heads. The 428 has billet main caps, BME rods, JE 2618 alloy pistons, and the J/E hellfire rings. The solid roller cam is being worked on currently for this combination. Both new versions of manifolds will be tested as well. BLP (Bo Laws Performance) will be providing all the carburation needs, and they will all be dominators. The manifolds will also be available with the 4150 flange. This CV-235 is first of 5 new Intake Port shapes to be released for the CV-1, and 1 of the remaining four will be another as cast shape. So there are 2 new as cast shapes and 3 new CNC'd offerings. The CNC shapes are currently being worked with to finalize the shapes, and get them scanned for CNC production. As soon as those shapes are ready, that information will be released also. And again, I apologize for the delay, we are working day & night to get this stuff completed and on the dyno. We are very excited and look forward to testing the new heads & manifolds. We are also working on Roland Racing's new 4/7-3/2 cyl. swap camshafts.Std & Lrg. journal will be available. These are the new grinds that we'll be testing for the new CV-1 program. Which also includes the development and testing of our new LightWeight IPN Forged Crankshafts. The cams & cranks will be available soon, and as soon as they are in my hands, pics will be posted. |

I would love to see what adding another 5 CCs to the window area will do, I think you could get that 347 cfm to come in much closer to .700" lift and you would still be at least 10 CCs down from a wide port E-head.

The goal for this head is 400-455 ci engines, we have a 428 being built now for testing! Dyno results will soon follow. Last edited by GREATGTO; 03-02-2010 at 07:05 PM. |

The ongoing developement by Jim at Roland Racing and those he is working with shows true commitment to wanting the best product possible for the $ spent. With all the unfounded neg. comments made and some were outright lies against the CV1- (you dirtbags know who you are-big name or not ) as they say proof is in the pudding. And the CV1 has proven no other head casting can be as wide of range possible use as the CV1. Not bad at all for a cylinder head designed to be a bolt on stock block to aftermarket block street/strip head.

Goquick there are quite a few heads that are just as versatile as the CV1 head. You are correct about the proof being in the pudding so show us a CV1 headed engine that is doing something that no other head can.
I do applaud Jim's on going R&D to make his product better. |

$10,000.00 on a set. Like you did on your high ports. In one of your post you make this statement 4 years ago when I started this motor I was only planing on making 700 hp. Here you are now 5 years later and you still just getting your car done. When it comes to any of the after market heads it all boils down to anyone with a blank check can make them work. Look at what GTOKID did with a set of E-heads, 8.80's and set the new record, get this there not even a wide port head. I talked to the guy who did hid heads, after all these years the E/head has been out someone finaly figure out how to get 400 cfm out of them. Why because someone was willing to spend the money.

One of the members, just for the he'll of it called Dan Barton wanting a set of
High Ports just like yours. $4500.00 just for port work didn't include intake port work. Now maybe it didn't cost you that much. But Dan got his foot in the door. With your build up. I do know I asked how much to do and intake like your $2500.00.

Sepcialy when there's no quality issues. Not a head porters head. LOL The only money is in guys like EC. What's going to happen when a guy is able to buy a CV-1 out of the box and make the same power as the guy who just spent $10,000.00. Head porters are going to piss their pants. So you better get all your thrushing in now while you can. Oh and don't forget about bad69bird who bolted a set on out of the box and made 1275 hp with a blow through. LOL

It would be easy to shut all of us up. Go out and put up some ets that will shut us up. People keep talking about flow numbers and stay tuned there is more coming. Well that has been happening for the last 2 years.
As for this new 235cc head what is its advantage over other heads that flow 330cfm? For $2500 you can have a set of CNC ported 330cfm heads from SD Performance. As for me spending money on the HP heads. I talked to Dan after he looked at the CV1 heads, he would have gotten about the same amount of $$ out me no matter which set I went with so $$ wasnt part of Dan telling me to stay with the HP heads. Also Jeff's performance isnt bad but his heads arent really out of the box they are have been cleaned up. So as for as I know there really isnt a CV1 headed engine running 9s with out of the box heads. |
