Sunbeam Tiger: Installing Turbo's

fasttiger · March 06, 2008, 10:02:24 PM

,Well after all these years of using NOS, I'm going to go with twin turbo's on my TIGER. I'm getting help from a company here in New Mexico called TURBO HORSEPOWER.
Got the idea after seeing turbo's mounted in back, and that's where mine are going. I've already got the turbo's mounted and the charge pipe's done. I'm putting a water to air in the trunk.
Looking to get approx. 800hp to the rear wheels, the turbo's are 61mm.
Should be up and running by June.
The car has ran 9:77@144 on the NOS looking to go low 9's @150 something, on street tires.
Maybe a race with the Tiger Eater when i come to Colo?

Jerry,
Sounds interesting. I have read about the rear turbos. It would really be good to actually see an installation and hear how it works.
Should keep heat out of the engine bay too.

I will try and get some pics out, worked 10hrs on Sunday doing the exhaust. Who ever thought that you could put two turbo's, one 3'' charge pipe, two 2 1/2" pipes to the intercoler in the trunk and two 2 1/2" exhaust pipes over the rear end and still have enough room for the 8 3/4 rear end. Its tight but none of the pipes hit and the only thing I have to do is make the bracket for the panard rod a little longer to clear the exhaust pipe.
Like you said Steve it will keep the heat out of the engine bay, plus it will make the engine compartment real simple.

Jerry,
Sounds like you're working hard.
Would like to see all that stuff in the rear end.
Are you going to the V8 meet in Port Wahington?
Would love to see it.

Jerry,
Port Washington is in Wisconsin. Middle of July. You can get information on this web site.
Hope you can make it.

Sorry Steve that's a little to far to travel, maybe someday after I retire my wife and I going to travel some and hoping the Tiger will be dependable enough to drive with this new set up.

Citron · March 26, 2008, 08:27:35 AM

Jerry,
Too bad about the Port Washington trip. Your car would be interesting to see and hear.

Thanks for putting up the pics for me.

Got the car fired up Sat. and drove it around, having problems on the low end tune sounds like a vacume leak but can't seem to located it.
It turned out better then I expected had alot of help from the guys here in Albq.

fasttiger · June 30, 2008, 08:46:50 PM

Got the car dynoed and made 5 pulls and ended up with 382rwhp and 393 torque.
This was done on a stock motor with 200k miles and thru a PG trans
Car drives great with the fuel injection and the turbo's come on at about 3200 rpm's and pulls hard to 5800. Can't wait to build the other motor but will have to wait, low on funds..

fasttiger · July 14, 2008, 07:32:41 PM

Went to the drag strip Sat. Car ran 11;98@116 on 5lbs of boost and motor starts to lay over before we get to the end.
Needs less gear or bigger motor

Citron · August 04, 2008, 03:21:42 PM

Jerry,
Glad you've gotten it on the road.
Good 1/4 mile times.
How about the Silver State Challenge?

Steve

fasttiger · August 08, 2008, 12:35:50 AM

Silver State Challenge? Grrrr, steve the car is really being set up up for 1/8 and 1/4 racing and of coarse for street use. I don't know about those prolonged high speeds. But one never knows, I can tell you one thing the turbo's don't stop pulling. On paper with 2:88's in the rear and the big motor in the car looking at 175-180 @ 8000rpms and 12 lbs of boost i think and i don't know if I could trust the 42 year old parts on the car or have the balls to run that fast.(it's a age thing)

Remote turbo is something I had considered for my 3.4L. Small turbo that wouldn't give too much lag- about 3-4 psi boost and all with an attempt to keep the engine mostly pure stock. I have seen that setup on 3.4L V6 Camaros as well as others.

I really like the setup!

I like SC more but the remote turbo just seems neat as long as its something else to hide because my car is supposed to look like a pup, not a monster.

fasttiger · August 09, 2008, 11:31:01 AM

So far with this stock motor setup it works ok, I don't think I have any more turbo lag then the guys with front mounted turbos.
I do like not having all the heat under the hood and also it is so much cleaner looking and nobody knows.
When we put the other motor combo in it will be setup for the turbo's that's when i'll be able to tell about turbo lag.
Turbohorsepower says he can redo the turbo's to get them spool alot faster but to wait till we put the real motor in the car.

Just found a Ford Turbo-coupe and asking about this in the engine section. I have two reasons- your car and that Hemi that outran me. Probably still will not do enough, but looking at a bunch of mods over time. Still not looking for Huge power, just something different. Glad to see these postings.

fasttiger · October 26, 2008, 10:22:04 PM

Twin Turbo Tiger still up and running great. So far best time has been 11:35 @123 mph, on 8lbs of boost. Changed the rear gear to a 3:55 but still has to much gear. Looking to change out to a 3:23 or wait to see what the new motor will do with the 3:55.
Will keep you all posted.

man jerry your car is like a test bed for the rest of us keep up the good work!! i love reading about your car with all the different things you have tried, awesome car!!

old hp 260 · January 27, 2009, 11:45:16 PM

was it hard to fit the 351 windsor block in your tiger?

fasttiger · February 01, 2009, 06:23:57 PM

We still us a 8.2 deck motor, it is a stock 302 block now. Just got the pistons for the race motor which is a 8.2 deck World Products motor which will be a 378ci with AFR 225 heads and a great turbo cam looking to make 700rwh on 12lbs of boost on pump gas. Should have it in the car by the end of Feb.
We raced the car in Phonenix and it went 11:30@ 125 on 8lbs. with the stock motor. With the new 3:23 gears
I hope the new set up will be as dependable as the stock motor we have'nt had a lick of trouble in the 9 months its been in there.The fuel injection is great , using the FAST system I really think that is why the stock motor has lasted as long as it has.
My wife loves how quiet the car is and enjoys riding in it. Its really a sleeper.
So why put a big motor in it? I've never been the smartest guy!!!
