Jeff your right....... you have much more experience with dsm/evo's than David Buschur.

Since Jeff says i dont need my BR frontmount intercooler i guess i should sell because i am on the stock turbo.

Btw i had a 17whp gain with that intercooler that br sells with my stock turbo... at stock boost levels.

 

Why are you so sarcastic? You asked nearly the same question HERE I'm simply asking for some dyno charts. I'm sure his FMIC makes power but I would like to know what the 20G gains are without the intercooler.

No need to be confrontational buddy its all good. BTW I'll look into FMIC info again but the last time I dug around on here people claimed the stocker was good for 400HP easy!

 

I guess you're just not getting the answer you want. Yes the stocker will "hold 400hp" although I'm not exactly sure what that's supposed to mean... Heatsoak is inevitable in the summer time if you do any kind of real racing. This is true even with the stock turbo at higher than stock boost levels.

The problem is most everyone if not everyone that gets this turbo (or any other turbo upgrade) is going to have an upgraded FMIC. Without actually getting the turbo and testing yourself I'm not sure if you'll find your answer.

 

You're basing your information off of claims when you should be looking at the dyno charts David Buschur has posted showing gains of ~14hp with his upgraded IC. Yes, it's possible to make 400hp with the stock IC, but id bet my annual salary that you'll make a lot more with an upgraded one.

 

I am not an expert and do not claim to be, however this is my opinion:

After seeing some of the gains witnessed by lightly modded Evo ix's I am planning on picking up an EVO ix turbo before I do my front mount upgrade-here's why:

I think bolting on the EVO 9 turbo could be more of a gain than a frontmount for an 03/04 w/ the stock 9.8 exhaust housing. If you can pick up a EVO ix turbo w/ the 10.5 hotside fairly cheap I think more gains will be realized than a frontmount alone.

I want the EVO 9-20G if it can shows gains at lower boost levels (21-22) The 20G-9 I think would show greater gains than a frontmount alone in an 03/04 again because of the 10.5 Hotside. I believe the 10.5 HS alone is worth 5+ horsepower in cars w/ the 9.8.

Here's the thing-I think once you start raising the boost over 22psi the stock frontmount is going to have a tough time dealing with this. I think once the boost starts getting raised - this is where large gains will be realized.

I am not disputing Buschur's claim of 15+ horsepower from a front mount at all. If it wasn't true, he wouldn't say it. I am planning to get a front mount in the future as I think it will help greatly. All I am saying is that where I am at in modifying my 2003 EVO, a stock EVO 9 turbo or an EVO 9-20G may help more than an upgraded front mount. Of course this is only my opinion.

 

Jeff Jeske,

From your post #150. Believe me, you are very wrong about the stock FMIC, it is a big restriction and needs to be replaced long before a turbo upgrade is every considered. Even our standard and deluxe kits will gain 15 whp over the stock unit.

The FMIC is more power for less money spent than the 20G turbo.

Okay. Fair enough. Thank you for your time.

 

You need to search and you will find the dyno charts you are asking for. Buschur has shown this time and time agian. Replacing the intercooler at the Buschur stage 4 level of mods will give you some gains. I will give my opinion as i just swapped out to the NEW Race FMIC Buschur sells. I am able to run 25 psi on 93 octane with hardly any knock on my car in florida weather. So the intercooler is worth every penny. I am also running the new Buschur evo-9 20G as well. I couldn't be any more happier with the Buschur products.

 

Right, we'll see in the summer, but right now i run 23psi(20g-9) on 93 with my Turbo XS IC. Its not worth beating around the bush for especially when you upgrade the turbo

 

awesome #'s... how does the spool feel?

 

like stock

 

Well I learn something everyday. I'm actually glad you fellas spoke up about it.

 

Good news is...........for me anyway. I was on the dyno with my RS again. I was looking at the logs and was noticing that the intake air temps were "broken". I got out of the car and checked the sensor and it was apparently fine. Weird. Got back in and looked at the logs again and then saw that the temps were in fact moving, just not during a run. This was odd as I remembered the air temps increasing in a 3rd gear pull with the 20g on the car at high boost. The pulls I was doing the boost was hitting 28 psi on and the air temps would start at 50 degrees and end at 50 degrees. NO change at all. I went back and looked at some old logs and found temps increases from before. I then pulled the inlet off the turbo to see what exactly I had on the car, found it is the current 20g-9-5 bladed wheel. Interesting. Interesting enough in fact that I put the normal Mitsubishi style 20G wheel'd turbo back on the car. Guess what, AIT's went back up. They climbed every pull by 4-5 degrees on a single 3rd gear run. HP stayed about the same as before, spool up was about the same etc. The turbos are close but the IAT's are pretty amazing. It shows how much more efficient the 20g-9-5 wheel is.

I have the 20g-9-5 back on the car again and have sent the other turbo to FP to have the wheel upgraded to the 5 bladed wheel.

With this bit of information I think come summer time and longer, hotter pulls that the difference in air temps between these two wheels is going to become very important.

I will upgrade anyone with our 20g-9 6 bladed wheel to our 5 bladed wheel for absolutely free. I'll even cover the shipping. There are only 7 of you out there. If you'd like to take me up on the offer just call and we'll have you drop ship the turbo and get it taken care of for you.

that is very interesting! it is very likely that the 5 blade wheel flows cooler air than the 6 bladed wheel, but it is also likely that the 6 blade flows more air.

if you ever wanted to do a cool test, put a boost gauge in the exhuast manifold, then you can really tell whats going on...

 

Why do you say that? I think if the temp is higher then the 5-blade is flowing more air. If PV=nRT and the temp (T) went up, the boost (P) was held constant, the volume of the system (V) was held constant (obviously because the turbo compressor housing and ducting was the same) and the universal gas constant (R) didn't change, then that would have to mean that the number of moles (n) of air was reduced slightly to offset the increase in temps to keep the equation in check.

I might be rusty on my physics, but I think this is the way to analyze the results. Hopefully, someone with more definitive expertise can chime in.
