Twin turbo gains

[Jakemax04]

Just wondering if anyone out there has had a similar set up as mine and then installed a twin turbo kit? More specific a s475 over stock kit and what kind of gains can I expect with stock sticks and cp3? How many tenths at the track would it knock off? I would be getting it tuned safe as possible cause I know it lives on the edge after twins I'm sure

In general you could pick up another 150 hp.

You'll have enough air on hand to get into the 11's. Whether your motor or wallet wants that to happen is another story lol

 

[Jakemax04]

Hmmm the wallet doesn't want it lol, but I've got a car I drive everyday so if it had to sit and wait for coin I guess it would be worth an 11 sec pass haha

There's a twinned dmax on Instagram that has 40k hard miles on stock bottom end.

40k miles would be good for me cause I hardly drive it anyway. But when I do it's usually to the track

After my twins I shaved about 4/10ths off my time at the track. Much lower EGTs too. When I went to the bigger injectors I shaved off another 4/10ths or so. I dyno'ed 560 with the twins then 620 after the injectors, but I don't take the dyno numbers too seriously.

Nice! Do you daily drive it? Only beat on it at the track?

I ran a 13.0 @103 on stock turbo/sticks 3years ago. When I put my 40 overs in and s475 over the top of my stock turbo and lots of tuning adjustments I got it down to a [email protected] I'm also at 4600ft. If been running like this for 3 years and 35k. Still on stock head bolts too. I see 55psi and egts have a hard time breaking 1400* towing is awesome too.

That's impressive with stock head bolts on there. I'm always paranoid about that. So it seems you guys got twins then realized injectors were needed to open up those twins? I'm curious what my stock injectors are capable of, it seems they aren't far from being maxed out

your stock fuel system will put you over 600hp with twins if your cp3 is healthy

Is that with or without lift pump?

My current 475/stocker just dyno'd 517 whp with only studs, "safer" tune, and a lift pump

Edit: a mile high

 

[Harbin_22]

With a 475/stocker setup with stock pump and 40%, I ran a 7.41@92-93mph 1/8 track. I was pretty impressed with it.

What was your 1/4 time?

 

[Harbin_22]

Never ran 1/4 with a single pump. No local tracks. Only went to the 1/8 once on a single then went dual pumps

 

[JoshH]

What was your 1/4 time?

The 1/8 mile time he posted would easily have been an 11.7 in the 1/4, maybe even an 11.6. Very impressive.

I'm very curious to see what my setup will do at 5200ft in the 1/4..
