Remote turbo SHO build V2.0

[strings1732]

I've got it all figured out. I no longer bottom out because I raised everything as much as possible. The setup works and works wonderfully. I had a few bugs but all of them are worked out now. no more testing is needed to figure this stuff out. I have it done and it runs great(minus the blow off valve).

I'm using the tweecer to tune as was said and Jason(yamahasho) is helping me to tune it. I'm learning but it's taking some time.

all the pictures I have of the setup are on this website. Just search for my forum name and the words remote turbo.

At this point the long pipes are doing my charge cooling, but soon enough I'm going to add water injection.

I turn the key to the key on, engine off position to run the pump after the car sits. I plan to get a cheap ebay turbo timer to hook up to the oil pump so I don't have to sit there and wait.

With a larger maf, and the tweecer you can input the correct maf curves and then the computer will do the rest.

 

[JustinSane]

what car is the turbo you used out of?

 

[strings1732]

I responded to your pm justinsane.




Update, The BOV did not blow up, it blew off the piping, but I went ahead and bought an HKS SSQV BOV and I'm going to go install it in a few minutes. If everything goes to plan, I may have some drag times tonight, with pics and video

 

[BlackonBlack89]

Awesome.

cant wait to see it in action!!!

So how much boost are you planning to run once you add the water injection

 

[strings1732]

Upwards of 20 psi.

can we see some pics?

I went to the drag strip tonight and had a few issues. I had a couple of boost leaks and kept getting fifteen second et's. I fixed the boost leaks and bogged it off the launch and still ran a fifteen. Then I tried launching harder to get a better 60 foot so I would be faster and I snapped an axle... I need to launch a little better to get my 60 foot times down from the 2.8's that I ran tonight. Stronger axles are needed so I can launch at 6000 rpms as opposed to the 4000 I tried tonight. This kind of sucks but oh well it'll.be fixed tomorrow and I'll try it again on Friday...

Must be some serious boost leaks and bad launches if you're only cutting 15's. You should be bettering that stock. You need to launch at that high of RPM's just to get into boost? That lag must be pretty bad in 1st then. Are you going to go with some stronger R-Axles?

 

[strings1732]

One of my hoses basically fell off my charge piping... I wasn't hitting but maybe 2-3 psi. At 6,000 feet above sea level, a 15 is not too bad, although I was running 14.7's on a 75 shot of nitrous. I fixed the boost leak and launched at about 4,000 and as soon as I let the clutch out, boost started to build and I hit about 4 psi. The problem is not the lag, it's the tires and suspension. This is where my system is nicer than most boosted SHO's... I don't have wheel spin issues when launching, I have too much traction for that. With the tires I'm running, It stuck and tried to go... Even when I launched at 6,000 and broke my axle, it stuck and went. It launches like a RWD car right now, I just have to get the thing dialed in so I can get a good launch and hit 13's at this altitude. When I broke, I launched and the thing jumped forward a good ten feet, with a broken axle. That really doesn't happen when you break an axle. Usually the car stays where it is, and the axle snaps in two. From what my friends say, The car didn't have any wheel spin, other than a slight chirp, and then it bogged.

First gear doesn't really lag anymore, it builds boost almost instantly, and in higher gears it builds even quicker....

 

[Toolman]

So what suspension and tires do you have?

 

[SASHO91]

I know how you feel Scott. I was there last night... I could not launch the car at all.. I was dropping the clutch @ 4k and still bogging the car. Then again, the track was soaked in VHT... Car would just hook and bog....

 

[strings1732]

I'm running 235/45/17 nitto nt555's at about 20 psi on 17X7 fittipaldi flames

Full suspension includes:
tpr bushings everywhere but the front sway bar(stock rubber)
sho shop linear springs
Koni Adjustables, about a 1/4 turn from full hard in front and at full hard in rear
adjustable strut rods


The track was soaked in VHT and that could have been some of the issue as well, but even then, I don't see much wheel spin on the street either...

 

[Toolman]

The Nitto drag radial, or just the standard 555?

 

[yamahaSHO]

They are the standard 555.

Just for the record, for those that don't quite understand altitude and power loss, take your best NA time and add about a second or more and that'll be your best time up here. A 15.8 up here is about a 14.7 at lower altitude. When he breaks 13's, it will be one helluva fast car.

I am planning on being at the drag strip tomorrow with Scott to video tape him.

 

[platoribs]

I did, however, embarass a GTO on my way over to Scott's. It was fun.

I had to share this with one of my BBQ Team who recently bought a GTO and has added Kooks headers, tune, and shifter... 400+ out the back. I'd love to blow past him in a 12 year old FWD SuperSHO!

Why do you use an N/a example as a reference to an FI car? Being from Colorado, I can fully understand the influence of altitude on an N/a car but isn't there a distortion when you are talking about FI? From what I understand, an FI engine can achieve the same level of O2 in the manifold
at higher elevation as it can at sea level with a slight increase in boost level.

I'm no expert so can someone explain the boost-altitude equation to me?:type:

 

[JustinSane]

NA cars do suffer more then boosted cars at high altitudes, boosted cars can run higher amounts of boost at high altitude then that same car could run at sea level, the air is more dense already at sea level. but what i dont understand is the need to luanch at such high rpms, my SHO with its dog weak 3.0 motor is only getting a best of 91 mph in the quarter and on street tires i launch at 2 to 3 k and get 2.4 60s, is it the charge pipe acting like a restriction untill boost builds that gives you such a bog and or weak luanch at anything under 4k? VHT is there to help the 60 not hurt it i wish all tracks kept the 60 sticky i been to some that dont.

 

[SASHO91]

point being, there could be too much VHT on the track. I had the same thing happen last night...

I could hear my tires as I rolled up to the lights...
If I launched at 2-3k it wouldn't do anything... I ended up launching the car at 4K and still bogging it. I did not want to go any higher in fear of what happened to Scott.
Allthough, I was pulling 2.2-2.4 all night. And I know, if I was able to get the car launched properly, those numbers would have been a bit lower.

 

[JustinSane]

oh man you had it prefect, when your shoes get sucked off your feet when you walk across the track it is perfect, our local track is to stingy on the VHT on simple friday night street races they seem to save laying it on thick for only the big days or events. i am jelouse you guys get such a nice starting line on a street car night. once you learn to luanch on that sticky starting line you wont ever go back trust me its all in timming the clutch and gas to get no bog , keep at it you will get it sorted. just remember getting it right in a SHO it means clutch abuse, i know we all would rather abuse our tires but in bracket racing you need to be the same every pass and tire spin is to much of a variable to go rounds, our track has some of the top racers in the country and you dont go rounds here unless you have good RT and run the numbers. check us out at www.beaversprings.com

 

[SASHO91]

hmm.. guess I wouldn't be a bad bracket racer then....
pulled nothing but 15.1 the whole night. and im not even kidding....

But that's not what I was going for...

I did put the clutch through alot last night. It had a hard time grabbing with the 4k drops... any higher and I don't think it would have held..
