Installed B16g today and I'm shocked!!!!!

[BOBS90TURBO]

I installed a new Big 16g today and fixed a couple of broken exhaust manifold studs and a housing gasket that were all leaking air. I do not know if my 14b was bad or it was all the exhaust leaks I had but with this 16g my car feels freaking awsome.

But the weird thing is, it really does not slam you back untill around 15psi, Don't get me wrong it has a lot of power at 10psi, I would say equal to the 14b at 10psi, but at 16-20 psi, holly shit, I wish I had done this a long time ago. And yes I have all the support mods except fmic.

 

[herostar]

sounds like me when I got my big28... have fun with it, and get that front mount so you can reallly turn teh boost up

 

[GSX4LIFE]

Uh, he said 16-20psi. A B16G is not really good more than a couple psi after that. I would say he already has "turned up the boost".

 

[herostar]

well I'm just saying that since he doesn't have bigger injectors or fuel control, adding those and turning it to 21-22 psi will make a huge difference

 

[BOBS90TURBO]

Yes, I do have fuel control, I have a apexi s-afc and 550's, I should be in my mod profile.
I also have Autoalchemy fuel fittings off my rail, 6n SS lines and a HKS AFPR, fuel PSI set at 40lbs. All I need now is a FMIC.

O-yea, with a FMIC what boost could I run? Is 20 about the max.

i agree, the most u wanna boost on a big16g with all supporting mods on 93 octane is 23. after that its not really that effective. unless on race gas then maybe 24 psi.

I'm getting my Big16g in couple weeks........I only have Injen intake installed in my car now. I also have Greddy boost gauge, JoeP mbc, HKS ssqv, apex fmic still sitting at home waiting to be install........
my question is what other mods do i need in order to run the big16g nicely and safely??

Just do a little searching man. You need a full 2.5" exhaust ( at least .. I chose the 3" ) and you need larger injectors and some way to control the air / fuel. Obviously new intercooler pipes as well.

 

[screamin talon]

im running 19.6 PSI on my t25 with no problems.... yet

1. I love it when people say they are runing "XX.X" psi. Right, because your boost gauge and boost controller are accurate to that degree... I think not. It's more like you're running "19-20 psi."

2. Running that high a boost ona T-25 is pointless, the car will probably be faster at 16 psi.

 

[TSIfreek]

Yes I agree,
BOB keep your boost down to no more than 15 psi utill you get a front mount. Turning up the boost higer will be just forcing hot air in the engine causeing knock and the computer will be pulling timing loosing power . I would recomend the BR street core kit.
Hey glad to see you got everything takein care of and the car running well.

The T28 and the 16g is actually really different. The T28 spools a lot quicker than a 16g. The 16g's boost comes in more linear then it hits hard up high when full boost is made. The T28 just hits hard to begin with cause it spools so quickly.

 

[BOBS90TURBO]

You are right about it hitting hard when higher to full boost is made, it feels like a totally different car to me, where my old 14b would spool quick and hit fast and run out of steam early, the big 16g SEEMS to spool much slower and then "BAM" hits hard around 11-15psi.
Hell I don't even have to down shift any when getting on the expressway, where I would have to with the 14b, the 16g is a louder wirrrlllll sound also,,,,..

Ands thanks TSIfreek, it has taken me a while to get it all worked out, and some money to naw it's all worth it now that I can beat my wifes brothers 03 Mach1, at least I was takeing him for the first 1/8th of a mile or so and still pulling and then I started getting into some cars and let off. I was shooting to do my car as close to yours as I could. And I will check into the BR street core kit, I do not know shit about FMIC yet, but I do need one now, and then I should be done,"right"?

 

[screamin talon]

yeah i really hate when sombody talks about a car and dosnt know what they have . ive got the greddy E01 controller and it reads digital unlike the bs autometer in most dsm's and its pretty acurrate as well . also it made more power at 20 than at 15 or 16 . you may wanna look at the persons profile than to assume what u think they have

 

[TSIfreek]

:laugh: Yea alot of crack addicts say they will stop and get help but they never do. We have the same sickness but its leagle.
Bob, you may think you are done but there will always be something else. If I were you I would get that FMIC and be done with it. Turn the boost up to 17-18 psi on the street and be happy with it. You will have a fast car that very few V8s will be able to keep up with on the street.
As far as what I am doing I decided to pull the motor and have it freshed with .030 over ross forged pistons new bearings and all. Mitch at enginetecs is doing all the machine work for me. I am hoping to have it done by fall and get to the track to put some 13.50s passes on it (still have the stock side mount)

:laugh: I hear you on that one man! I somewhat melted my #4 piston . And I swored I was just going to bore/hone with new STOCK pistons... Now I'm starting to assemble my shortblock with my new Wiseco pistons and Eagle rods. Waiting for my SI valves and Crower springs for my head. So much for stock!!

Well, without a front mount, stay under 17 psi. The Big16g is a very inefficient turbo, and will make massive amounts of heat . But it is inefficient for a reson, it has a pretty big wheel in their, which allows it to run high boost and still make good power, alothough it is overheated boost.

Local guy, stock motor, big16, supporting mods, FMIC, at 26psi and race gas, 11.0@116.
Full weight car, 3 count knock max on that run.

Yeah when I boost about 15-16psi My timing gets pulled and my car slows down alot. I was running 14spi but I just put my 3in downpipe on and it creeps to around 16psi now. Im thinking of turning it down to 12-13psi to be safe. I guess we weill see.

[TSIfreek]

Andrew put a 2.5 inch down pipe on it insted of that 3" piece and you wont creep or loose any power. Eveybody on this bord thinks they need a full 3" exhaust and they run into creep problems when useing a 14b or 16gs.
3 inch is great if you have an external WG but 85% of the people on this board just run internal because its cheeper and I see it not needed and a waist of money on a 16g,s.
I would rather set the boost at 15psi and not have it creep at all than having seting it at 13 psi and having it creep to 16 and pulling timing . (which way will be a faster car)
If you guys think you need 3" down pipes what does Jonh shepard need for his 900hp+ talion. 8 inch

No he needs a full 3.5 inch exaust, and is thinking about 4 inches.

Creep is not realized though the size of your exaust, but the lack of flow into the wastegate opening. Proper porting will stop boost creep, so take your turbo off, buy soem good bits and have at it. I have seen multiple Evo 16g's hold 11-12psi, with proper wastegate porting, on full 3inch exaust cars.
Keep the 3inch DP on the car, you WILL loose horse, especially at the higher boost levels, with a 2.5 inch DP. Prot the O2, or get a new unit to get the most out of the full 3inch exaust and your new turbo porting.

 

[rarson]

im running 19.6 PSI on my t25 with no problems.... yet

:laugh:

I'm love to know how you're forcing the T-25 to hold it past 5500 rpm... considering with no boost control whatsoever, my T-25 wouldn't make more than 15 psi at that rpm.

I wonder how much horsepower you're losing being that far off the efficiency map.

 

[BOBS90TURBO]

Hey TSIfreek, It's funny you say that about the built engine, I just got my other dsm back from being stolen,it's a 90 gst,anyway the motor is blowing smoke, more like blowby, but the strange thing is it runs smooth and has good oil psi and does not heat up past the middle,even on 100+ heat days, I have not opened the engine up yet, but when I do, I am going to start learning how to be an engine builder , I too have bought a set of ross pistons and Iam going to talk to BJ tommorrow about a crank etc..(the guy that builds sheps engines and the BJ's sheetmeatal intakes), so yea, it has me so bad I am going to be modding on 2 dsm's

Also about the boost creep and the 3"inch DP, I bought a 2 1/2" after reading about so many getting the creep w/the 3", and with only a ported 2g o2 and 2g mani, I have zero boost creep. Guess I am doing something right or getting lucky

BS Maybe 12.0 ...if he went 11.0 at 116mph he broke half way. At 11.0 he'd be trapping about 125-130mph roughly

good to see you are enjoying it ... i run a big 16g at about 17psi (can't seem to get it back down to 15psi) and it hauls.

yeah i really hate when sombody talks about a car and dosnt know what they have . ive got the greddy E01 controller and it reads digital unlike the bs autometer in most dsm's and its pretty acurrate as well . also it made more power at 20 than at 15 or 16 . you may wanna look at the persons profile than to assume what u think they have

, your stupid, plain and simple, your t-tosmall is just blowing hot air up high....
