FP-Big28 vs Big 16g

[turbonawd]

I've heard that FP-Big28 is better for AWD and Big 16g is better for FWD. But is there a huge difference between the two in top end power and pull?

From what I understand, the FP-Big28 flows at 520 cfm vs Big 16g's 550cfm which is not much of a difference.


has anyone been able test out both turbos?

Ive been in modded awd's with both turbos. They seem pretty identical if you ask me. I really dont notice much of a difference in boost threshold, spoolup or topend. They are both very good turbo's IMO. I dont know what you mean abotu a turbo being better for FWD though...
The only reason one can be better is if someone is a big wuss and is scaird of a little wheelspin (which is innevitable when making power in any non awd car =)) and thinks that by getting a larger turbo and wanting a little more lag that it will help in the long run. I see no sense in this thoery, but that is just me

i think this is the idea
t-28 spools faster you get more wheelspin than if you were moving already i read it somewhere here
only someone that tried both could answer that
i'm newbie so don't take my word for fact

I'm in the process of finding the thread ....... There is a guy that got a personal E-mail from Robert @ FP & was told that the FP-Big28 will flow
550CFM when asked directly via E-mail I think .

That's exactly what Robert @ FP told me over the phone about a year ago when I first purchased mine.

Would not want anyone to under rate the
FP Big-28.

the theory is simply that the Big28 spools insanely fast which would be great for the AWD but not so great for the FWD, the 16G is a little laggier but only be a few hundred rpm which isnt much to keep you from spinning. the 16G supposedly flows a little more air which means the top end power would be better.

If you were to put both these turbos on the same cars FWD and AWD their results would most likely be near identical.

I am in no way trying to start anything... I just noticed a comment....
Robert @ FP said himself to one of his outspoken customers that the
FP-Big28 will flow 550Cfm...... This means that the FP-Big28 will flow the same CFM as a Big16G right ?(550CFM)
The 16G is rated at 505CFM .

Were you talking about the regular 16G supposedly flowing a little more than the FP Big-28 ?

This guy has owned a FPBig28 and a small 16G. He says in the post that the small 16G spool's slower but pulls much harder than the FPBig28! Again that is the small 16G! Which is supposed to flow 505 cfm. The turbine and compressor housing just seem so small for the FPBig28 to flow well. The compressor housing will heat up the charged air more than the Big16G and the turbine housing will make your VE of your engine go down due to exhaust reversion (ie. the engine will work hard to push the exhaust through the little turbine housing and not flow well). You may be able to run 24 psi, but I bet the air is hotter and not as much is flowing through the engine as with the 16G's.

Please note that he neither has fuel control nor a front mount intercooler, two of the things that are critical for making the various T28's shine.

So in the case of the 16G supposedly flowing a little more than the
FP Big-28 ..... wouldn't that make the need for the a Front mount intercooler & fuel managment system more urgent ?

 

[DCJ98GST]

I would think a FMIC and fuel management would be required to make either one of these turbos shine, but maybe more neccessary for the FPBig28 because the of hotter charged air.

I think the point is clear that given the same setup the 16G's will flow more. I dont think that a FMIC will make that up with the FPBig28.

That's funny you say that cause there is a guy that I have talked to that started the big ass FP Big28 review thread that's over at DSMTALK.com that goes by ProjectGSX. He had a 16g killer and swapped it out for the FP Big28 and said the Big28 was stronger. Go figure! If you don't believe me just read the 50 page review on it. FP rates there Big28 at 360 hp at the crank, it even says so on there site. The Big28 has only been out for a year now as compared to the 16g series turbos that have been out for years. Give the Big28 a little while longer and then start ranting about it. I personally think it's not been out long enough to compare. For now though... the FP Big28 is still the only turbo out of the 28 series turbos that have run high 11's. 11.8 @ 119 to be exact.

The 16G is rated at 505CFM .

Id like to see where that comment had taken place, many many people have asked FP what cfm the Big28 was rated at and they refused to give out any information. Ofcourse now every company makes a 28 series knockoff so I guess its not as big of a deal but if it truly flows 550cfm then it should have the advantage over the Big16G in spool up time and it should pull just as hard up top. Ofcourse CFM isnt everything, getting a turbo to reach its max CFM takes alot of effort.

Here's my opinion, both turbo's are so identical... it's not a big deal.

If you have a 2G, get the T28, you can trade in your T25 core, and lower the price. But to get a 16G you need parts to bolt it up to your 2G, and that costs money.

If you have a 1G, go with the big 16G.

I agree with this comment TOTALLY. That is why there is SO MANY arguments about the Big28 and or AGP T-28 versus the Big 16G. They are both just to close in comparison to the Big 16g to make a comparison IMO.
