Viper

[coupe]

This is a little different kind of "Snake" than usually found here on Streetstangs, but what the heck...at least it's a domestic :D

Got this car a few months back, it belongs to a good friend:

http://www.supernaturalturbo.com/viper/viper2.JPG
'99 Viper RT/10 / 8.0L (488cid) V10 / Aluminum block & heads.
1999 was the last year of Forged rotating group, and it has the same cam and driveline of the GTS. It is a good platform to start with.

I have been slowly gathering parts and deciding on options to increase the power a little beyond the stock 450rwhp figure. Will update when I can.

[coupe]

For starters, I have been waiting on a prototype fuel-pump hanger that has finally been produced. I should have it in about a week. Got to feed the beast more than a single 255lph pump can deliver.

(gas-tank had to be removed through the trunk...it is not a fun job :tlash: ...it sits behind the cabin, in front of and above the rear wheels)

[TheJeanyus]

Upgrading the fuel pump, eh? Sounds like more than a few bolt ons are in order? :turbo:

[militarymustang88gt]

got NAWZ?

Very nice looking fuel hat. They just came out with a triple hat for the cobras as well.

Must be planning on racing turbo 'Busas from 100 mph rolls. :jester:

Those cars make sick power with forced induction. Keep us updated!

[Greg03Cobra]

nice car, i want a ride & a race.

[coupe]

racing turbo'd busas from 100 mph rolls
LOL. Yea, I've seen some of those vids. Might give it a try anyway. :D

Here's a few things so far...

[ncontt]

oh so that's where that 74GTS went...lol :metal:

You'd be surprised.

[ncontt]

you're right...I was surprised...geeze, that's cheap for something with that kinda power and only 23K on the clock....

[Dale McPeters]

Nice project Matt. That thing will make good power with the turbo's!! :D

Now we know who is making all the money....:jester:

[coupe]

Now we know who is making all the money....:jester:
Yea. My buddy who owns the car. :eric:

But I am looking forward to "tuning it" on the road. Got the piggyback calibrator today. Injectors and drag radials (oops! shhh) next week.

ETA? Hopefully in a few weeks now.

[96GTS]

Loved the Vipers since 91. Good project....

[EHardy1971]

Cool project Matt!:metal:

[myillwillinc]

awesome.....

[DSkeet]

I hate you Matt.

[coupe]

Got a couple more things for it...

[coupe]

Coming along nicely. Got the tig welder set up at the house now...things are fitting pretty well actually.

[rtusnake]

What size turbos are those?

[coupe]

They're 61mm turbos...basically GT35's, but built in a more robust T4 frame.

[rtusnake]

Nice. I know where a cobra is if you want to fabricate some more kits :jester:

[coupe]

Okay. :nice: But we got three projects in line. We're sorting out two already-turbo'd foxbodies for their respective owners and we're also doing a single turbo install on a 6.0L Chevrolet SS pickup.

[Dale McPeters]

Ok who is doing the tig welding for you? :jester:

[coupe]

Well...I can do it, but it's not pretty...so I just cut and fit stuff...
I leave the welding to a pro: my buddy Reed.

[Dale McPeters]

I was just joking with you but it looks like he does excellent work. :nice:

[95cobra]

man that is going to be a beast. :hump:

[Dale McPeters]

Update? :jester:

[coupe]

Yea. We had to cut turbos loose and move them outboard about 3 inches to clear inlet air filters and some other stuff. Wastegates are on. Exhaust is run to the back. Fuel lines are about 95% done. 60# injectors and regulator are installed. Only things left are install oil scavenge pump, install gas-tank back in car, hook up to the fuel lines, splice in the fuel-timing controller, plug in laptop, and "Fire."

[coupe]

Went through the options on this tonite:

https://splitsec.com/wp-content/uploads/2013/12/FTC1-s.jpg

It's a piggyback fuel/timing signal conditioner called "Split-Second."
Has onboard MAP sensor and datalogging. www.splitsec.com (http://www.splitsec.com)

[Dale McPeters]

:nice:

[SilverBack]

That's a pretty slick little controller. Is it the ESC1 or FCC1?

[coupe]

Finally got the fuel system finished. Here you can see the triple-pump assembly installed, lines connected, the 3-to-1 fuel feed, and the Y-block feeding both rails. The lines go like this: three -6 into one -10 into two -8. Return is a -8. Pressure tested to 100psi and no leaks!!! (Triple 255's peg the pressure gauge fast!)

[Dale McPeters]

Very nice. :nice:

Is that basket like the ones that you can now buy for the mustangs?

[coupe]

I believe it is Dale. Rtusnake was mentioning one for the '03 Cobra.

I got the first one for viper. I had to drill and tap for a -8 return (it only had a -6) and I had to make some retainer screws/washers for the "vent tube" as it was not held in with anything other than an o-ring...did not want to have it come out!!! It is secure now. :nice:

Yep I have seen the ones for the mustangs. They are nice.
You did a nice job on the vent tube. I did not pay any attention to the screw/washer retainers until you mentioned them.

[SlowJoe]

can i test drive it??????????:jester:

[ncontt]

I LOVE the black fittings.....:drool: looking good, what about putting some 45's on there right where it merges from 3 to 1?

[95cobra]

:drool: you do good work

[coupe]

what about putting some 45's on there right where it merges from 3 to 1?
Yea...thought about that after it was installed...but there really is plenty of room there for that big setup..so it will stay like that. I am going to put plastic loom over the stainless where it rubs up on anything...just to make it last. Already did that under the car and up into the tank area.

I can get you some Kevlar sleeve from my work if you want to use it instead.Its black and you can cut to length

haha, that's usually how it goes, AFTER the fact, but shoot if you've got the room then by all means I wouldn't change it. Why spend an extra $25 bucks on fittings, those bastards are expensive (fittings in general that is).

[coupe]

Yea. This car has about $900 in lines and fittings.

Kevlar sleeve from work
That would be cool. Think you could sneak about 10-foot of it though? I need to cover the two -8 lines running up beside transmission to back of motor...and then a few small spots here and there.

The plastic stuff is sufficient...and the viper uses it on other places, so it's not entirely out of place.

[qkjuicedpony]

I can get you a whole roll.about 40 feet or so.

Just let me know.

>Right Click, Save as (http://www.supernaturalturbo.com/viper/startup.wmv)<

Fired it off, and it started on first try! :banana:
Had to keep bringing fuel out becasue it was very rich. Then after letting it run, we discovered oil in the turbine housings...the scavenge pump is not keeping up with supply...so we are going to add another pump.

[TheJeanyus]

Hell yeah. :metal: That thing is going to be retarded.

Good to see my old laptop actually doing something constructive. :D

[Skillet]

That's the loudest laptop I have ever heard.

[ChipR4cam]

That's the loudest laptop I have ever heard.

:lol:




:werd:

[coupe]

LOL. Yea, it's a bit loud...but it doesn't have all the exhaust on it yet. The pipes go down the side and end. The rest of the exhaust will be put on and run out the back of the car.

That thing is going to be retarded.
Yea. It should't even break a sweat at 750rwhp. Too bad I'm not going to have the car at track day.

[TheJeanyus]

750rwhp.
At 6 psi? :jester:

[SlowJoe]

LOL. Too bad I'm not going to have the car at track day.

why not? dont u have to tune it in?:jester:

[waypastcrazy]

I would love to check out that beast up close!

[coupe]

why not? dont u have to tune it in?:jester:
Gonna do some drivability tuning and then the throttle tuning on it. Stick it on the dyno, then deliver it. My customer is getting anxious...especially since he heard it run!!
But he has a 600rwhp vette to keep him occupied in the meantime. :drool:

[SlowJoe]

hell there is a few spots left open make him bring it:jester:

[coupe]

hell there is a few spots left open make him bring it:jester: He lives 800 miles away. LOL.

[95cobra]

:drool:

[coupe]

Okay...got it running again with second pump and the turbos are dry!!!

But only on the turbine side. :( We're getting a little oil in the compressor housings...:tlash:

turns out we're having a syphoning of oil out of the oil-galleys down the feeds into the top of the turbos after shutting car off! :banghead:

Easy fix though... checkball that opens with oil pressure only. Should be driving this thing this week/weekend! :banana:

[Shorty]

:drool:

[coupe]

After trying a couple different valves, we finally have dry turbos!! Everything working PERFECTLY!

Put the car on the road tonite with the wide-band on. We did some drivability tuning and everything's working nicely. Havent gotten it past "0" psi manifold pressure yet, but it's still pretty strong. :p

Did I mention this thing turns some heads?! Damn.

[SvoBrown]

They were all looking at you Matt. Sure would like to see this car up close. Or when it goes to dyno???

[SlowJoe]

track day 2 weeks away!:jester:

[95cobra]

more video?

[Scothew]

Matt, is it at your place? I need to meet up with you at some point just to see this beast! (since I drive right past your exit and hell your work everyday)

[coupe]

Yes Scott. anytime.

[coupe]

:cool:

12.5 psi. Pump Gas.

746rwhp / 745rwtq.

(Did 609whp on the wastegate at 7psi.)

Big "THANKS" to Tracy @ Mobile Electronics: www.speeddreamz.com (http://www.speeddreamz.com) :nice:

[Scothew]

Damn I aint never seen a johson outboard make that kinda power :drool:

[EHardy1971]

Matt,did you make any passes in it last weekend?:shrug:

[myillwillinc]

that viper sounded awesome today......

[Skillet]

What's up with that torque dip? I bet that's a wild ride. Do you have to give it back now?

[coupe]

The fall in torque and power is where we are basically "limiting" the ouput by pulling out some timing.

I never made a pass in the car because it's not mine. However, I can tell you that rolling into the boost at 70-80mph will send the tires up in smoke! It could be a wild ride if you wanted it to be. :D

[TheJeanyus]

:metal:

[ChipR4cam]

That looks like a party.:yup:

[coupe]

Car left today for it's home. Kinda sad to see it go, but I do get to work on my car now.

[SlowJoe]

great job:metal:

[QWKSNKE]

Nope. you get to work on my turbo now :D

[coupe]

touché. :nice:

[coupe]

Update on this car...

It was sold two weeks ago. :( Due to a busy business, he wasn't driving it as much so it sat in his shop and took up space. When someone asked if it was for sale, it wasn't a hard decision to say "yes." The rest is history... and a big bag of $100 bills.

Good new is my buddy had it for 2 years and never had one problem! He drove it whenever the weather was nice (winters suck up North) and even took the car from DesMoines (his home) to Chicago to visit his brother. :nice:

[ncontt]

everything is for sale....for the right price!
