I would like to see the datalog assuming you have one.Well..to say that I am happy in any context would require a bit of a stretch..I would have to adjust my thinking.
I would have to consider 440 fwhp adequate. The car would have to weigh 3400 lbs with me in it.
With the fully dressed 2j in the car, the added weight of the turbo, intercooler, water reservoir, a2w IC, the tork troll torque arm, the PH bar, the LJK, and the big pig 4l80 added to this car ..it might not be unrealistic to guess that the car “may weigh” that much with me in it...I don’t know
What I do know was that the car was ( for the lack of a better term) Slow as sht. 7.69@94 mph, 1.9 60’ times. The video looks slow, the car looked like i was going to grandmas house.
The burnouts made people turn and look, because it sounded like it was gonna be something to watch..However just as soon as i left the starting line, im sure everybody turned around and went back to what they were doing...Just another slow assed street car.
Inside it felt like it was haulin ass..( except the initial hit..it was always sloppy, and laggy) hence the 1.9 60’ times.
the car ran flawless, no sputter, no weirdness in any way...just mind numbingly slow..fully confirmed at the time shack on my way back down the return road where it just happily putted back down after the pass..
To say that i was disappointed....yeah,....that is putting it lightly. Clearly, my concept of “fast” needs........fine tuning.
Trying to foot brake it at the line ended up pushing it out of the beams...The 2 step left sluggish,..there was no quick way off the line.
it was a kobayashi maru.
The good?....The car runs great. It runs the 1/4 mile in 12 flat, and got 23mpg on the way to the track, where it was driven to, and back w/o incident a total of 80 miles RT. It’s quiet enough to talk to a caller through bluetooth, and when not on the phone, the LJK sings his ass off. The car looks good, sounds good, seems to now be dead reliable, and pleasant to drive.
Why am I disappointed?
Its probably the tiny turbo....No, it’s definitely the tiny turbo. This engine, notorious for making power through 7500 rpm is done at 5500 rpm on the datalog. The tiny turbo, a blast on street tires, isn’t up to the task of feeding this engine.
The previous 72/68 Chinee turbo that was on there showed me that if I kept my foot in it long enough for it to come into big boost ( 22 psi) things got real scary at highway speeds..it just took about 3 seconds to get there..4500-7500 was a whole different ball game.
It’s my fault that i have the tiny turbo on the car,...I told the guy that I wanted instant boost on the street..( I have that) I told him that “ Whatever it makes at 25psi, is whatever it makes, and that I wasn’t trying for street hero status with 800-900 hp” But,..I also told him the expected power goal was 550-600 rwhp.
At present, I’m nowhere near that.. like about 150-200 hp away from it at the bottom number, and that’s provided that my car weighs in at 3200 lbs w/o me in it. If it’s lighter than that, it’s even more miserable.
Im confident that Work turbo will work with me to get this sorted out, but before they do anything like swapping stuff out, I’m thinking they’re gonna expect me to try and watch a boost gauge while beating on the car, so that i could compare what I think I saw to the data log..unless there is a better way.
or...I could just be happy with what I have
Fat chance.
Well of course I did...This was after I bumped the boost duty to 44, and nothing changed. MOF there was 23 psi on that DL I showed you before we tweaked the timing to 14 degrees.I would like to see the datalog assuming you have one.
at 23 psi I would think it would be faster than that, however 23psi from this turbo can have less mass than that from a larger turbo at lower boost.. that sounds like its not possible but we have to consider backpressure..
you could tap the exhaust manifold and add a 1/8npt fitting and hardline it 2' across the engine bay or up into viewing range in the cowl area and add a 15psi gauge to the end. this will keep the gauge from burning up from the heat and allow you to monitor the backpressure.... honestly thats what the turbo work guy should have you taking a reading of. I bet its in the 10+ psi range at full steam
now you could do the same deal with the tubing and place a 30psi transducer on the end and datalog the backpressure to get a real idea of what its doing under all circumstances.. yes an electronic boost gauge would do for a temporary installation if you have one lying around I use a cheap-o liquid filled gauge
I'll put an electronic cutout right after the down pipe and trigger it based on boost, and dump the exhaust straight out if that turns out to be the case.. They wanted me to check boost pressure drop on the cold side, and wanted to ck timing...AFR is still too fat in the high boost maps..looked like 10.8 iirc at one point.I would like to see the datalog assuming you have one.

backpressure will be highest before the turbo if the turbo is the restriction.. I bet it is.I'll put an electronic cutout right after the down pipe and trigger it based on boost, and dump the exhaust straight out if that turns out to be the case..

It does have a real tiny exhaust housingbackpressure will be highest before the turbo if the turbo is the restriction.. I bet it is.
It does have a real tiny exhaust housing
What was I gonna do if the car only ran that? remind me...Ahhhhh, what???
This was all you said that I could find.If that was the case, the “ ohsht” would be replaced with pieceofsht.
