Doc, I'm very well aware of the twin-charged S1. Mine almost beat it if Hector and I had
been able to come to a mutual decision. As far as your issues with the swap, I find it odd
that I had no problems whatsoever with fitment or operation.

Bolted right up. And purrs like a kitten with a 2.2" pulley. Granted, I did alot of top end work to get it to run that pulley. Most 95 top ends won't survive with anything smaller than a 2.5" pulley, and very few with a 2.4".

Most guys don't run Nitrous for intercooling like you and BlazinLo do, Jason. And I've gotten where I am with no valvetrain or head modifications whatsoever, on a bone-stock bottom end.

The point my car proves is quickness and speed on a budget, simply by improving what the factory gave us.

The TB is the least of your worries. It won't properly mate to a Gen2 supercharger like you have. It just makes your SC inlet into the biggest restriction, and causes potential coolant leaks. There'* absolutely no benefit whatsoever to changing just the TB with no other changes.

I don't run nitrous at all. I've been thinking about it lately, but not just for an intercooling effect. Honestly I aboslutely love what you're doing. The only thing I'm concerned with is that proper study is done before stating something as fact.

PM.

Proper study is being done. For the first time in Series 1 performance, something is being done on the street and on the flowbench for real. And both the street and the flowbench agree.

Imagine buying a house with a sprinkler system installed in front yard. Coming out of the automatic valve is 1" pipe. Then it runs through 3/4" pipe for 20 feet, then back to 1" pipe to each sprinkler.

That'* the Series 1 lower intake manifold. I've been spending every minute on my car for the last year (actually over a year now) trying to get the stock top end to flow to it'* greatest potential. I got it where I thought it was the best, and found some help from another member. It'll get better.

Awesome, can't wait till everything is worked out. A lot of good testing can go a long way. Dyno is also important though. What did the flowbench say?

My personal opinion is that dyno'* don't tell much due to the variablility of them simply from pull to pull on the same car. There may come a day when I dyno, but it'* too late for me to dyno before the mods.

The flow data I'm referring to is with regards to the LIM alone. The thermal analysis is on the SC itself.

The thermal analysis on the SC is important for reducing the boost charge temp in the LIM. The flow data on the LIM is important for properly feeding the cylinder heads in the most efficient manner possible.

If you can increase the velocity of the intake runners, you can actually improve the spray pattern and atomization of the fuel.

You're right about the dyno but that'* why it'* important to always use the same one and not count very small differences in gains. Such as, it would be difficult to dyno a 3hp mod. But 20hp should show up every time.

It'* really neat you're going through all this effort. I'm really curious about the flowbench on the LIM though. What numbers did you get?

I didn't flowbench the LIM'* myself. Someone else is. I'm not going to speak for his data until he does, but it'* remarkable. More than a cam alone can do. This is with the nearly identical porting that we both did, and an additional change he made (the most signifcant). Coupled with adding one of the design elements of my intercooler plate to the LIM itself, the difference will be real.

I think the performance of my 93 speaks for the porting already.

Hrm...Curious why you wouldn't post simple flowbench data, we're not exactly in the ultra competitive racing circuit here. I'm also a bit curious which cam you used for the flowbench comparison but maybe that was just a figure of speech. Did this person only flow the intake or the heads also? My train of thought would be that he did flow the heads also, which is how you would be able to tell that the porting is better than 'a cam.' If so, that would be an interesting tid-bit once declassified.

DrJay, the whole world is not out to cut into your Cam business. I'm not revealing my source nor the data per his request. But he'* an old Muscle-car mechanic and an Aeronautical Engineer now, so I think he'* got us both beat in the brains department.

When the time comes, it'll be shared. Too many people have jumped on untested or unproven designs and ideas on this Forum. And it'* blown up in some of their faces. That'* why you don't see the data. And that'* why you won't see it until we've proven it on the track and street in more than one car.

Safe approach, don't you think?
