13.67 @ 100.76 with a 2.059 60ft. I trying to locate the video.

For now here is a 13.88 pass. Keep in mind this car is almost completely stock.
Cone air filter, larger I/C, no cat, fwd stage2 comp, drag radials and ground effects removed(fixing them).

I was actually trapping 101mph with just the cone air filter, I/C, and muffler removed. still had the cat on and stock ecu. The new ecu definitely provides more torque, as I am spinning first and part of second now, which I did not before. I will be adding a wide band to see where i am at. car seems to be running very rich.

Definitely think that the I/C may be the key to the boost creep. When I get the old turbo off this week, I am going to open it up and see what was going on in there.

I'd be half temped not to mess with the turbo unless it leaks :fingersx:

your idle may be too rich, but your making too much power for 14 PSI to be rich. I've seen less than 100 MPH with 24 PSI and a hybrid from rich. The VNT is a restriction, like it or not, to get that trap speed your in the ball park for AF. What I've noticed from FWD computers is they are a little more rich at idle and it makes the idle smoother. A wideband or OTC would give the clues to idle AF.

My fwd stage 5 in my lancer at 21psi is 9.1-9.4 a/f at wot, at idle its 12.4. Most of her cals are very rich. Thats a good thing, because I would rather dial in the fuel myself.

Pretty sure I have no choice in changing the turbo:tsktsk-tisk:

Yes, that's the down pipe with oil pouring out:dancing:

No worries, I have a brand new one on the shelf:thumb:

haha you should see how much oil my S60 turbo is puking out the compressor side. The BOV spits oil all over the radiator fan in the upper pipe

Jeezus, That's like 30% too rich. You either need to dial out the fuel or add 30% more flow. You're washing cylinders down being that rich.

Trust me I know, that's why it just sits in the garage. I will lean it out after I put the new clutch in. I can't really tune it right now with the clutch slipping. I also run an alky system in it and have to get the nozzle right. Like I said its a garage queen for now.

keep in mind oil causes lower octain and then detonation, a little is normal, a big puddle isn't

dragbaron, Yes sir this is the one. The front air dam is messed up, but its there and can be fixed for sure. my buddy actually bought the car before me an fixed the head and all. so i had to pay a whopping $1700 for it:dancing:
Seriously, worth every penny and then some. i actually prefer buying td's this way. i really enjoy restoration. I have the interior done, except for the headliner(working on headliner today) and getting the drivers bolster fixed. I am pulling the motor and trans this week to replace the dead turbo and very weak stock clutch.

i can surely help you out with the boost controller. its more of just a bleed valve than anything else. send me a pm.

I will also walk you through the process of upgrades I did, and more importantly, in what order. Last thing you want to do is a bunch of mods and then have problems and not now which mod did it.

Hey all, Finally got the new vnt turbo installed and decided to mate the engine with my relentless performance A413. took the car out around the block and it feels friggen great. I had the trans built eons ago and never installed it, I really love driving a standard, but figured what the heck, while i have everything out why not try it. I should be hitting the track next weekend, will post the results.
car is still basically stock:
fwd stage 2 comp
cone air filter
larger intercooler
stock downpipe, no cat

you may find the auto choice is better with a hybrid turbo. Your 60 ft with a stick isn't bad, so an auto doesn't help as much. If you run 110 MPH and high 13s with a 2.6 60 ft the auto looks real good lol.

Its not a hybrid turbo though, its the stock vnt. Gary used to cut 1.6's with his auto so I am not sure what you mean about the 60ft?

not with DRs, not with stock weight ratio and with a much lower total weight and a lot more power. Garys race cars are much different than your setup.

60ft time is the time it takes to go the first 60 ft, every .1 faster in 60 ft is .2 faster in the 1/4 mile.

I brought up the hybird as an example of power, I know it has the stock VNT. The auto trans will suck a good chunk of WHP to turn vs the stick. In a true street car the 2.0 60ft you mentioned and the ET / MPH your running shows that your setup with a stick is working pretty well. If your running a 2.0 on DRs you should run a 1.80 or better in the 1.7s with slicks. That isn't bad for a street car. Move the weight around, do the suspension work needed and put the car on a diet and it'll go 1.6s or better. SHADOWs Charger is a street car, without weight moved around and has a stick and hits 1.5s in the 60. Big 26" slicks and a lighter weight Charger and all the suspension mods get you there.

It's just that your doing really well so far really for what it is, that's why I am suprised you added an auto to the car. Basically cutting down a winning combo :shrug: A little more tire, maybe some suspension work, posi etc, stuff it might not have yet? The car may lose 4+ MPH going to the auto.

Really, I thought i just had to put Gary's trans in and I would get those times:bang head Just kidding of course.

I definatly see what you are saying. I put the auto in because my clutch was getting very tired and I was getting very tired of waiting for the new clutch to show up. I figured why not try it, I have not seen or heard of one yet. It will be interesting to see what the car will do with it. I do not plan on keeping it in, but for the next couple of months racing it sould be fun to tinker with. Then, when my new clutch shows up. I'll put the a555 back in.

My CSX will never be a full on race car. Everything I am doing I can undo. After all its a #'d car and I am in the process of restoring it back to such. I just have plenty of free time to work on my cars.

On a side note, I have the M&H slicks on the way, supposed to be here sometime this week.

Also, while the a555 is out I am going to open it up and check everything out and most likely add a lsd. It and the motor have over 130k on them and will be rebuilt. Like I said in the begining, i am just out to have a little fun with this car untill I am further along in the restoration. Then it will ba a garage queen like my shelby lancer and glhs :thumb:

My true race car is the 1986 turbo z, but it is still back in michigan. I should have it out here late march then the fun will really start. Who knows, maybe all this testing I am doing on the csx might just involve a future powerplant combo for the Z....

I wish I was able to put a manual in my 89 daytona while it was running good. I was getting 2.4 60ft 13.8 at 100mph. and 0-60 in 5.6 with the stock mitsu turbo. But that was on 18psi. After dropping in a T-2 Garrett that the Pope sent me out I was doing flat 13.6 at 104. 0-60 in 4.9 Think I got my 60ft down to 2.2 on all season tires. And that was on a terrible a-413.
