first time i started my own thread to show some work off over hear on HT but u guys seem to like all fab work so here it is.............. this is for a dual cam 2.0 neon its my "medium" runner design. i have welded in the depressions under where the injectors sit and then removed the humps from the inside of the runners, caused by those depressions, i have gasket matched and ported the runners and cleaned up the outside. this manifold is going to be pared with one of my heads also. the head was completly ported and polished on the intake and exhaust with no work done to the combo chambers. i have gasket matched the intake side so its going to be a nice smooth flow in and left a little bit of a lip on the exhaust side for anti reversion purposes. the head has gotten a 5 angle vlave job with stock sized valves and it has already been on a super flow 600, im waiting to go pick it up and get the results. im pretty confident that the result will be good as this isnt my first head. well enough with the talk here are the pics.............. and let comments begin.

and here is the one i made for or speedivas (Ang's) black SFWD car........
steve lockett said he should have the car dynoed hopefully this week. the car was making approx 420 whp with the stock intake and 52mm t-body. with the new intake a 65mm t-body im hoping that number will jump up quite a bit. the whole point of this manifold was to get more power and to move peak power higher up in the rpm range. we'll see what happens. he did street tune it and said he was having to add 6% more fuel to keep his A/F ratios around 11:1 at 6500 rpms. and when he gets on the dyno he'll be taking it higher than 6500. im excited

 

looks very very good

how much does and intake mani like that run?

 

most of the ones i do are around 400.00 or so shipped (depends on what all u want done to it). i can make completely custom intakes with stacks too but the price will jump up a good bit.

 

Looks good man

Ive never done any 2.0 heads, but they look very similar to the srt heads that ive done. The only real differece(visually) seems to be the exhaust ports. The exhaust ports on an srt head are extremely restrictive...but those looks like theyd flow a good bit more in stock form. Do you have any pics of the head before porting? Post up the flow numbers when you get them...id be interested to see how the 2.0 heads compare to srt heads when ported

 

honestly i think the 2.0 heads flow better than the PT/ SRT heads despite what everyone thinks, of course i have no proof. for one the exhaust valves are 1.5mm bigger in the 2.0 head making the diameter right under the seat and area in the bowls bigger. im pretty sure the mouth of the port is bigger than the PT/SRT ports also. (and the intake ports are identical) i have a pt engine that is going in my drag car and im debating weather i should use the pt head or get a 2.0 head. i will post numbers when i get them for sure. eventually will have numbers for everything stock and ported......... well if its for a neon anyways. and i had some pics of stock ports let me see if i still have them.

 

did you just use a stock intake manifold flange and cut the plenum off and make your own? looks good man

 

the fab looks nice. it is obvious you put quite a bit of work into it, but i'm not sold on the design. i'd atleast radius the plenum floor leading into the runners. something like this:

 

what machine are you welding on?

 

yes i use stock manifolds and modify them.

i would radius the openings of the runners but im using 1/8" sheet aluminum so i cant radius it that much. not to metion its a PITA because the runners are rectangle. a cnc machine would do wonders here, and the design does do its job.

im using a syncrowave 250

 

ahh i have a syncro200 and i use a 250 here at VT to weld for baja, needless to say the 250 is awesome for aluminum.

Not as awsome as my inverter

 

i really wanna get a dynasty 200 dx......... its my dream machine.

thats true. I get to use a Miller inverter tig everyday now

Nice fab work on the manifold. Pics look like a soap opera though

 

I have a thermal arc 185.

 

nice work!

 

have you ever thought about radiusing the ends of the runners and lowering the plenum floors to slightly past flush?

similar to this: http://www.full-race.com/catal...1.jpg

 

i have thought about it, but its not as easy as it sounds. thats why i can do a completely custom intake with stacks. i can pull the stacks through the holes in the plenum floor so the mate up tight close to the top of the stack with out me having to fill a huge gap with aluminum like if i were to use a stock manifold.

 

work on your porting. Since these pics I've done all my manifolds welded inside and out...including the plenum. I did the first "semi-round" plenum for a neon two years ago. I think "chuck" on the org has one as well as "trickey".

 

u mean blend the runners to the plenum better? yes i know. the last 4 manifolds that i have done have all been blended like the pic u put up. and i have always welded my plenums inside and out. are u saying that im trying to copy ur plenum design? because all the ones that i have seen from u have had the design pictured above. i will be making one likes urs for ritfordprobe though. only reason being is because hes runnning a 75mm ls1 t-body and with my standard plenum the t-body mounting holes wont fit on the t-body mounting plate.

looks good

 

and while i have this thread back up here are some shots of a single cam neon head i just finished.................

yeah we call it "radiusing" the runner opening. No...not saying you're trying to copy it....You havent seen much of my work then lol. For ritprobe....make a TB flange thats larger than the plenum....your plenum doenst have to be THAT big. You'd be surprised at the power you can make with a plenum that's volume is 125% of the engine. I've done a lot of dyno work with the manifolds.... We're getting a flowbench here soon at work... I'll let you know what I find ur manifolds look good. One thing I would suggest tho....charge a lot more for your manifolds 400 dollars for one of those isnt worth your time. I know how long it takes to make one.

I hate having to explain why things cost what they do. Time is money.
