if his car wasn't running right (by the way we both were running 21 psi) and if he would have missed a shift, he would have told me. Don't you think so, well since I know him?

 

All I know is that 3 car lengths is a big difference and the result is not consistent with the dyno differences talked about here. Besides, I've seen you drag race atop parking decks, Joel, you're not too bad!

 

OK OK enough with the three car lengths and back on topic.

David,

Can you please explain how the larger turbo makes less horsepower than the smaller one cuz I'm REALLY confused, thanks.

Me too, but we all know the answer, tuning, thats it.

 

We have a Buschur500 turbo kit for sale right now. It has 100 miles on it and is in perfect shape.



No need to wait, as we have it ready to go.

 

I don't even want to open the can of worms to find out how you have our BR500 kit for sale.

I am in the process of getting some compressor maps faxed over. I am going to look these over and either stand behind what I said about the HP and larger vs. smaller turbos or I am going to admit I am wrong and blame it on poor tuning.

Stand by for some results.....

Buschur, it no big deal. We just have a customer with your kit who wants to change to something different.

 

Hey guys. I was wondering if you guys have a an O2 simulator for my cat? if so can you pm with price?

Thanks

 

that's awesome david. I'll have my car back on the dyno tonight w/ the ams gt35rl to see if it acts the same as it did w/ the 580 on it. i'll post the results asap.

Must be the same guy that had brought his car there with the kit and his AEM EMS that we wouldn't send the MAP for the EMS there to get it started?

Actually the owner said Tym was putting together a Map for him. So I guess you just lied to him. Anyway we don't need the map anymore because he is going with our GT35R/Equal length manifold kit.

 

Alright, I have some compressor maps here in front of me now. From what I am looking at I am full of ****.

Let me just get in another small story. Needless to say I own a few different cars. One of which is a turbo Buick. I was going through some small issues with it and was talking to the shop that does our turbo work. After telling him what the car ran on pump gas and the boost I did it at he suggested that a smaller turbo would work on my car better as it would be in it's peak efficiency range more than the one turbo I am running. This is what started this entire idea.

Now that I have called and talked to the owner of the the shop and looked at these maps I guess I am for the most part under the wrong thinking.

The turbos that WE are offering for the EVO should make more hp than the next smaller size on pump gas at the same boost levels. In other words the BR440 that made 401 whp here should be able to be outdone by the BR500 and then teh BR580 too.

I am not seeing this happen on cars getting dyno'd though. The race gas numbers are coming up pretty good but not the pump. I guess it comes down to who is tuning it or maybe it is our MOON dyno.

The compressor maps in front of me make even less sense, concerning the numbers we are seeing.

Ya know what, I have no idea what to say to explain this, I am confused myself.

Bottom line is from reading these charts and talking with the guys (3 seperate ones at this point in the day) the larger turbo should be making more power.

The only exception from all this would be when you get to a point when the turbo is so large that the lag will keep you from making useable power in the RPM range you can run the engine.

First off, I would highly recommend not calling me a liar. The one thing you can bank on is I don't lie. Tym told him we would NOT send a map for the AEM EMS to your shop, I was sitting here when he told him that.

I wish you were closer to us than California.

that's exactly what my 580 was doing. it was absolutely dead until 5K, but when it hit.... oh my god dude. i just wish i could have reved the engine to 10K!!! It was some violent $h!t man!!

 

That's right Mark actually squeezed 438 on mixed fuel, so once we put the full race and turn up the wick to 30 psi we'll quiet some people down. On straight 93 octane pump gas, he managed 386. So, I think thats pretty darn nice for pump gas brotha
