What’s the turbo setup you have on your sled . I run a custom made turbo setup on mine also with precision 5558 turbo and this new setup spools fast and pulls hard . I’m running msd mc4 on my rx1 . Can you tell me your carb setup . Where your needle clips are and what main jets you run . With my...

Good day everyone . Have a question for you guys . At what hp level does the charge pipe and intercooler size start losing its effiency . I’m running the powderlites intercooler still and it’s only 2.25 thick . I have a new header design on sled like osp use to build and a bigger turbo 5558...

So you didn’t loose and bottom end fun .

So what gearing and chain are you using . How is the bottom end pull and mid pull with your setup . What sled and what’s all done to sled . Thanks

Has anyone tried the 25/50 gearing on there Ltx . Stock is 24/50 . Does the stock chain still work with 25/50 and how did you like it if you tried it out . Thanks

I have a turbo kit if your looking for one

It’s the .64 a/r . Thanks also

It’s the 5558 turbo . I’m shootings for 500 plus hp .

Some of the progress so far . Lots of work fabricating new header . Now I know why headers aren’t cheap to buy lol . Should flow nice this setup .

Gonna build one I think . Bought a merge collector to build one with also. Bought a precision 5558 turbo also for sled .

What is the limit Hp of a front mount 4 to 1 header . Say you change the header flange and weld another one on and install a gt 3076 . Will the front mount be too restrictive of a header for good flow . Thanks.

That’s the plan but the Garrett 2860 isn’t cutting it no more . Bought a precision 5558 for it now and making a new header for it this summer . Motor is already built so time to turn it up my friend . Lol

Good day . Do any of you guys run precision turbos on your sleds . I see lots of guys run them on there artic cats 1100 and they seem to run nice and quick . Most Yamaha turbo sleds I see run Garrett . What’s peoples thoughts on the precision turbos . Thanks

You have any evo 4 flashed pcm for sale . Thanks

Yup same one bud . Good gaskets

Should be a stock gasket . I went with remflex gaskets on my turbo and works good . One at the head and one underneath the turbo . On both ends of the header . Turbo side and head side . Try remflex gaskets

Would a 100 ohm one work . Seen a post on a search about 100 ohm . Thanks

I am looking for some info on how to eliminate the fuel flashing symbol on my rx1 gauge . I went with a differnt setup for racing and not using the front mount turbo gas tank . I know there is a diode that people were using to get rid of the flashing symbol. Thanks for any advice also .

Try that and an orange secondary spring from thunder products. I run that setup on both our vipers. You’ll like it

Thanks for reply . As for horsepower I’d say I’m over 450 plus . So 3 inch is good enough then
