TO THE DYNO ROBIN "Batman Qoute"

[perfworks]

I still got the stock IC, and I did take my weather stripping off. The dyno runs are done with the hood up, so the weather stripping is not a factor there. Ill be directing air from the front of the car into the filter area. ITs more of a separator for the filter then just the shield like Injens.

Ill find a pic of what im talkin about and post it.

well when we meet up in july for the spoolin open house we'll have a lot to talk about.
good luck man and if you need anything you know where to find me

 

[perfworks]

if you get a high performance radiator they are usually have the size and take the fan out you can extend yuor shortram like i did to the front of the car, the gain is noticable.

good point bro.

Great job! Any plans on how to make the wideband work next time?

 

[boostisgood]

I got an autometer egt, but need to get a diff sensor. from what everyone says, the autometer sensor is slow to respond. Ill get the HKS one, and hook into my camp system with it also. That is digital, and real time there, not as slow as a mechanical guge.

Ill also see if I cant put thier wideband sensor into the bung i out in for my EGT.

 

[arkitek]

Nicely done boostisgood! Finally the info I was looking for.

Confirmed my suspision with the K&N which I took off already a week ago. The air simply gets too hot behind the intercooler right where the K&N filter is. We really need to reroute it Injen style or make a shielded air box right behind the left headlight if we're to use the K&N.

 

[2001GTI1.8T]

Hey guys, I'm new to this forum. Currently owner of a 2001 GTI 1.8T. I am looking at getting this car for my GF, she really likes my car but we want a four door. I wanted to see what kind of power these cars are putting down, sounds good. My last dyno was 200whp and 232ft/lb of torque, and I imagine a modded MSP would be good for atleast this much. I hope that there will be a fair bit of aftermarket stuff for the MSP, I think we will all have to wait. Even the 1.8T took time to develop the aftermarket since the older audi 1.8T's are mounted opposed. We went to the Mazda dealer today and the sales manager said there are no test drives for the MSP, is this true? Although the specs speak for themselves it seems a little insane not to have a demo car at the dealer.

 

[boostisgood]

yeah, no dealer will give demo rides to a browsing buyer. You have to have a strong buying commitment to get one in the MSP or EVO or SRT-4. Thats just how the dealers are doing it. Just like a checy dealer not letting someone walk in and say, hey lemme test drive that corvette ls1 over there. Too much of a risk for them

But it is a great car, Ill have new dyno results posted within the next 2 weeks with some "minor" mods like a boost controller and downpipe added.

 

[kwiktsi]

Wow, that is interesting about the K&N vs. stock air box.. I wonder if it is the heat that is causing this or just the design of the stock box.. I know you lost torque, but what did the HP look like up in the RPM's with the K&N and without?

I know I felt a much faster spool with my K&N and a harder pull, but that is also at 10 psi. Maybe at stock boost, the stock box is better and the increased boost needs the increased flow. I would be curious to see this comparison . I have noticed that this car is GREATLY affected by intake temps above the 4500 mark due to how rich it runs, but the weather strip removal and FPR kit helped a lot with that. The only time my car has felt flat sice was last night after I left the car idleing for about 45 minutes while talking to a friend in a parking lot. Other than that, it runs very consistent now.

Joe,

It dipped down hard right around 5200 rpms, Im figuring it was due to the hot air and uber rich, open loop. It kicked right back up, after the ecu did something to compensate for it. Im takin the sheets to my aunts in a few to get scanned. Ill post em later tonight or tomorrow.

Im hopin that the higher boost and fpr will help out with the orque loss issue with a shorter run of the SRI. The heat shield should also help alot too there.

Most dyno pulls are in 3rd gear. If its a 6 speed its in 4th. Most power is made in 3rd gear that is why they pull it for a 5 speed there.

What is our gear ratios?
Should be doing dyno runs in the closest gear to 1:1.

 

[boostisgood]

(dunno) I have no clue what the gear ratios are. Hold 1, lemme get out my cheat sheet.
1st 2.207:1
2nd 1.82:1
3ed 1.31:1
4th .97:1
5th .755:1
Final drive is 4.105:1

Doing the dyno in the gear closest to 1:1 is the first I ever heard of. So now I guess its time for me to get flamed for my dyno sheets (flame2) WILL IT EVER END?

Not quite true...went with 2K3 mazdaspeed to look at the SRT-4 and the dealer was practically begging me to take it out for a spin. The car was so crappy up close that I honestly had no desire to drive it...and I love fast cars!

I can understand that, but other similar cars for the same price and performance do not have these restrictions. When I bought my 1.8T they let me take it out alone. It's not like we're talking about a supercar here. I was just surprised, a lot of people would never buy a car they couldn't test drive. Oh well, too many test pilots I guess.


As for intake air temps/performance losses, I'm quite sure the MSP suffers from severe heatsoak like the 1.8t. The intercoolers are almost identical size but the MSP is probably in a worse location, too close to the rad and engine. I see about a 20-30whp loss between runs. A good FMIC will more or less eliminate that problem. Friends with 1.8T's and FMIC see maybe a 2-3whp loss between dyno runs. FMIC is well worth the money.

Interesting Craig. . .
Oh yeah, wait, I'm a turbo MP3. . .142 :bs: :wtf:



That sucks that the K&N would lose that much. They do tend to make the car sound a lot better though.

As for test drives, I think that sucks too. But much like sportbikes, most dealers won't let you test drive them. I guess as I get older they assume I'm more responsible though, so I might get my way. Can't go test drive other cars, always makes me want them though.

As for the dyno stuff. . .very cool that you're doing this. Keep it up!

 

[soundbombing]

what does is say for the name of the dyno on the dyno sheet? dyno.......? thanks.

 

[unwrittenLaw]

So it sounds like a K&N is better off when the psi is increased...but for stock levels, leave the stock airbox on? Is this a safe assumption? Also, what are the benefits of having more HP gains from the K&N vs the lost torque? I want to put a big K&N back on when I up the boost, but dont have a heatshield..do those ones that wrap around the filter work?

 

[2001GTI1.8T]

The largest gains I saw on my 1.8T were stock airbox and ITG panel filter, dyno'd better than a K&N by about 3hp. Now I have a CAI with K&N cone filter which I think does cost you some low end torque but well worth it for the better breathing in higher RPM's. You can see quite an improvement on the dyno graph from 5k up. I think one of you guys should make a CAI that drops through the round hole in the drivers side fender. You would need to relocate the resevoir but it would make a nice location. The 2003.5 is perfect since it does not have the fog lights and therefore a nice spot for a little RAM air effect. If anyone wants to make one cheaply here are two options. 3" or 2.5" PVC pipe and fittings, or 2.5" or 3" PVC electrical conduit which you can custom bend with a hair dryer. Try it out, it will cost you about $15.00 and is functionally the same as any fancy intake you can buy.

boost you did the run in the right gear. you want it under 1:1.
third gear is your best gear. 4rth is on the "overdrive side"
even if its only .03 off the 1:1 ratio.

Listen i just want to go off topic for a second here.
This new guy on the forum 2001gti1.8 came on here with a bit of knowledge. Its nice to see a non mazda owner with the amount of class that he has and come here and help out the site the way he is.
I just want to extend a welcome to you and keep up the good posts.(thumb)

Thanks man, it's nice to see everyone isn't as hostile as some here and many on the VW forums, heheheh. As far as I'm concerned we all have a common goal, to have fun and hopefully make our cars faster. I'm not one of those people that thinks they can outrun something out of their league. I don't even have an MSP yet and I'm dying to see what mods can and will be done. Keep experimenting guys, bolt on parts are only part of it. As far as knowledge goes, I'm an electrician, self taught mechanic but I do all my own work, I'm building a 2L turbo rabbit from scratch as we speak.
