Re: TPI Cross Ram Construction Thread

I tried yesterday to find the discussion of your intake on Speed Talk. I'd like to review what has been said. I submitted my registration so that I can search the site. Looks like there may be some interesting things going on over there.

Re: TPI Cross Ram Construction Thread

I am not sure I posted the cross ram on Speed Talk. I will have to check. I know I did on on the large tube TPI.

Re: TPI Cross Ram Construction Thread

Any news on the new design? I'm brainstorming on the design for my new intake. It will be built on the base of the Edelbrock 7110. The key to using this base is the flat, separated cam valley cover. It will allow alot of room for working on the runners. The more I look at it though, the more I think I may just have to cut the existing cast runners down to the flange and build new runners from scratch in order to get the entries to come up where I want them. It will mean alot of fabrication. I'm doing an engine right now for a freind of my son who is a pipe fitter with Intel Microprocessor development. I'm hoping he can point me towards one of his fabricators who works alot with aluminum. This is just a funny thought, but they work alot in stainless as well. What about a stainless sheet metal intake?

Re: TPI Cross Ram Construction Thread

Stainless steel will work has it has better heat transfer qualities(less) than aluminum. However it usually is more expensive to do. I think aluminum would be easier to work with.

I was not expecting to re-purchase my large long tube runner. So right now that one is on the front burner as far as TPI projects go. Also it looks like California is going to up the ante on smog inspections. Apparently they are going to install cameras at the smog shops. This will be a game changer if it comes to being.

Re: TPI Cross Ram Construction Thread

I'm anxious to see what shape your intake design takes. I'm constantly revisiting my design concept and considering its strengths and weaknesses. Stainless would be more expensive but the fabricators that my son works with at Intel work extensively with it and may actually have an easier time making an intake from stainless than with aluminum. I will probably go with aluminum though since that will make it easier to use a precast base, like the Edlebrock 7110.

California seems to be quite agressive in pursuing sub-zero emissions. I'm sure the leaders of this movement would prefer that our performance vehicles find their way to the crusher sooner than later, replaced by something powered by electricity. All fairly nonsensical at this point in time since much of the country's electricity is still produced by burning coal or hydroelectric dams, either of which is infinitely more harmful than the emissions from our few classic cars. But try to convince the policy makers of this.

Hopefully, at some point they will reach a compromise and pay less attention to the older vehicles which are short in number and see few highway miles each year. Oregon has already reduced the scope of their testing by eliminating the roller dyns, testing now at idle only, and removing NOX from the list for tailpipe testing on pre-OBDII vehicles. OBDII vehicles are tested for DTCs and monitors only, using a generic reader at the DLC port. They also provide a waiver for early OBDII systems, allowing a vehicle to pass with as many as 2 monitors incomplete, so long as the vehicle did not present at an earlier test with DTCs in either of the systems for which the monitors are not completed. This gives us some grace in getting borderline vehicles through and helps some of our struggling customers keep their aging, 96-02 vehicles on the road.

In the area where I live, there is no emissions testing required for registration, due to the lower density of motor vehicles per square mile. The fact that our state government is on the verge of bankruptcy I'm sure has something to do with all of this slackening of emissions regulations. However, if you look at this issue from a practical standpoint, ignoring the rhetoric of zealots on either side, it really only makes sense to focus most attention on the type and year range of vehicle which see the most use. This would be factory stock vehicles made in the past 8 years. The OEMs have done an excellent job of developing the on board diagnostics on these vehicles and have made my job of diagnosing and repairing emissions related faults quite straightforward. If the powers that be want to effectively reduce emissions from performance vehicles like ours, the best thing I can think of would be to limit use of our vehicles to 4,000 miles per year. Most of us don't drive our modified vehicles more than that in a year anyway. I'm also hoping that in the next few years, the age limit on emissions testing will be moved up to the 20 year and newer mark.

Re: TPI Cross Ram Construction Thread

I don't see California becoming more "sane" if you will on car smog inspections. Usually they turn up the heat every couple of years. My thought is if the car blows clean then let it pass.

Re: TPI Cross Ram Construction Thread

Oh, I should have mentioned also. I understand that CO2 is soon to be added to the list of measured emissions gases. It is a greenhouse gas after all. The feds are already cracking down on the OEMs to reduce CO2 emissions on new vehicles. Don't be surprised if California, the land of too many wealthy people with too little to do, jumps on that bus. Again, I hope that they focus all of this on newer vehicles and not on classic cars. Hey, you could always move to Oregon.

Re: TPI Cross Ram Construction Thread

Im strongly considering it.
Ca just costs too much to live wages suck crimes higher than ever and it isnt going to get any better.
Giving things til this time next yr at the latest. If things Im working on pan out cool otherwise Im hightailing it out and never dropping back in.

Real simple solution out there for cutting smog like crazy ;its not stiffening smog laws. Cali is WAAAAY to liberal to see a cut and dry solution

Anyways stay with it I dig frankenstein projects and the thought/effort/OCD that goes into it regarldess of the result.

Good stuff!

One of the reasons I live in Arizona. Emissions test is $12, and my custom license plate costs more each year than the actual registration renewal.

Re: TPI Cross Ram Construction Thread

Oregon now charges for the test, even if the car doesn't pass. Not bad for me I guess, since this might encourage people to bring their cars to me for pretesting and repair or adjustment before they go to DEQ. Either way it works for me. If I was forced to live in one of the counties where testing is required for licensing, I would probably feel differently.

I live in Marion county, north of Salem, here there is no testing requirement. If you're serious about moving north, give this area some thought. You'll likely hate the rain, but the landscape and people are nice. Plus if you move into my area, we can get together for head scratching sessions over these projects of ours. I also have an excellent machinist, Archie Somers, who I would love for you to meet.

My OCD is in high gear over the IROC, ever since I made it to the track last month. Does it indicate some form of psychosis that I have waking dreams of a perfectly tuned, heavily cammed engine starting up and running just so? Between my IROC project and the hotrods I've had in for work, I'm hopeless right now. I do hope that the dual exhaust I'm going to fabricate on the IROC this spring ends up sounding like the 69 Mach1, 351 Cleveland project that I just finished. I think my 355 TPI is faster, but those dual 2.5" pipes with Flowmasters did sound very nice.

I also need to get the fuel system in shape before I go on to the new engine and intake. Having my fuel pump heat up and shut me down last month at the track was a huge wake up call. I thought I had that part covered, but not even close. I've gone back to design on that and will build a whole new system this spring, much more simple and straightforward. Magnafuel now makes high pressure gear type electric fuel pumps that are true constant duty. This gives me a whole new option for a capable external fuel pump.

I plan to start saving in earnest for my new motor in two months. $100 per paycheck for two years, plus any additional funds I come across through side work and such. The bottom end will run about $5,000 and I should be there in 2 years.

Re: TPI Cross Ram Construction Thread

That's a good link. The more I look, the more options I find for a good external fuel pump. I do like the idea of a speed controller to reduce pump volume at idle for extended street use. Would help keep fuel temp down.

Re: TPI Cross Ram Construction Thread

The problem was the intake runners sticking to far up into the plenum causing air flow problems above 5000 rpm. It did great up to that point. The solution would be to lower the runners in the plenum area, reweld that area after they are trimmed down so that a nice bell mouth can be made for good airflow into the runners.

So for now the project is just sitting on the shelf. I doubt if I will do anything more to it. A friend was interested in it and took it over to Dr J's and he wanted $1000 to fix it.

No, it is just sitting on the shelf in my garage. Also Dr. J has since gone out of business.
