Here are the thickness differnence between a Gen 1 & Gen 3.

 

The welds far exceed any of the previous models. The welds had to be much hotter to weld the thicker material and out of all 3 of the previous manifolds this Gen 3 is the only one that you can actually see the weld come through the inside. This is a good thing. Also to be noted, all welds have been ground down on the inside and no overlap of tubing is in the way of flow like prior Gens.

It looks like this manifold should perform much better, but only time will tell. And for the record, I run my afr at wot at 11.5 tops and on this last manifold (still on car and not in any of the pix) it started cracking with moderate driving around town & no WOT runs as I needed this to last as long as possible as its my only means of transportation till the TT gets repaired. I will be installing the new manifold tomorrow afternoon.

 

great products except for the rust issues on both the light bar and the air diverter
i've seen both first hand on other minis, so none of this surprises me

 

Thanks Tricklex for the pix best of luck to you with the install.

 

For a reliable street set up w/ a stock bottom end 12.3 is too lean. For a drag car probably not. But if you like to run on the verge of detonation than that's fine. I personally would like to run a little more conservative, and keep my rods in the block.

 

nevermind

 

Wait Perrin (I mean Alta ) produced a part that was subpar? NO WAY!!!!1

Heat control and the welds would have better penetration

What is your infatuation with Edge? Almost every post you make, it has Edge in it

+1 to that, sounds awfully lean for not only a boosted car (although it depends a lot on how MUCH boost), but especially for a car that is getting some of its boost from a roots blower. For reference, the WOT AFR of a JCW car (which I think we can agree is pretty reliable) is down around 10:1 (actually dips even lower at redline). What boost level are you running (another important question thats gone unanswered)?

 

Have you ever run a twincharged car or even seen one?:impatient

Bill

 

Bill, why would you ask a question like that, you give your 2 and even 3cents all the time about peoples moded cars yet your car is bone stock. Don't point the finger so fast.

 

seen one, yes, own one, no, but as Mariokart pointed out, theres a lot of literature out there that allows you to understand things like this, its all fluid mechanics, chemistry, and thermodynamics, all things that I DO understand quite well, and when coupled with my experience in tuning other engines I feel my commentary can contribute to this discussion, so I thought I'd share it.

Experience aside (as I don't feel it necessary to quote my resume for you here), do you care to address my actual statement, instead of simply trying to undermine my credibility? If you disagree with what I said, I'm all ears to why you disagree with it, and I'm anxious to hear how you feel about using that A/F ratio on a twincharged car. Use your apparent "experience" to explain it to the "noob" (as you seem to think I am), rather than trying to hold it over their head to insult them. . .

 

oops, posted under the wife's SN, btw, this is rubyred3. . .

 

Mario,
It's because I took the time to go find out from someone who actually had a twincharge and tested it for quite some time. Does that make me the expert? No, but I have more of a clue what is going on with the car than most on this thread. My car is not stock anymore but thanks for asking.

Bill

 

Still, I have one for and one against the antenna. Need more opinions.

 

So what was the A/F you were running on that twincharged car that you tested and at what boost level? I'm interested in your experience, you correctly pointed out that I do have no experience with tuning a twincharged engine, although I still think I have a "clue"? Also, lets not get into flaming each other, its hot enough in here, I'm interested to hear what you have to say, and would appreciate that you would at least evaluate my statements based on their content, not based on whatever lack of background you think I have on the topic.

Everything I know about boosted cars says thats a little lean for even a turbo car, let alone one with the inefficiencies associated with a roots blower being part of the system (tends to heat the air up more than a turbo; although I probably don't need to tell you that, that was more for the benfit of others who might still be reading).

 

If you read my post you would understand it wasn't my car.

Bill

 

I'm confused then, what did you take the time to go find out from this person then? I got that it wasn't your car, but I thought you were claiming to at least know something about it. I thought your statement was saying that you had helped test this other persons car, but apparently that was incorrect as well. Or were you just going out of your way to try and say that I DON'T know wht I was talking about b/c you went and saw this car? I'm just confused now, what are you saying?

 

If youtake the emotion out of it , I think you can read the posts as I posted them. It was very clear that I talked to the owner of the car who tested it for years. I am sure he had more experience with the car than the current ALTA owners since he had his before ALTA ever even made a kit.

The highest recorded ALTA kit horsepower has been 280hp, they made over 375hp with a smaller turbo. I would be inclined to think they have a better idea of how to make power out of the twincharge than what is being presented here. I am in no way an expert just relaying the information from the person who actually had the car. If you would like to talk to him personally I am sure he would be glad to talk to you at length.

Hope this helps your confusion on the subject.
My apologies if I offended you.

Bill

 

Isnt this reguarded as slander? I understand you are upset but this is no way to resolve an issue. Name calling? Come on now....

 

Offended I don't think is the right word, as I said, just confused as to why you tried to call me out on a lack of experience, as you seem to have even less relevant experience yourself:impatient. I talked to the helix people at the Dragon about their twincharged car, I guess I'm as much of an expert as you on the topic.

I'm willing to let it go though if you are, lets get this thread back on topic shall we. . .

 

The reply was posted to the board in general, it just happened to be under your post. Again we go back to the kits, even Helix has only made about 250hp so are they as experienced as the guy making 375hp? Definitely something to think about. I really can't tell how relevant your experience is either but knowing what others have done versus the crowd making 50% more horsepower I will go with leaders. This should end my post on this subject but if you want to pm me feel free to do so.

Bill

 

No problems with the Alta antenna personally. I know a few other guys that have them as well. No one has expressed any problems with reception.

Seann

 

um, if it was to the whole board and just coincidince that it was below my post, why did you quote me in your post?

sorry to belabor this topic, but call me out and I'll call you out. . .

 

I was using that as an example of the thread. It was not the best of examples based on the number of posts that now clutter the thread.
