I was wondering why so many people have swapped out their novi 1000 for the 1200. Is there any real performance gain from this? I guess I don't understand how it would make a difference. if you are making 10 lbs of boost with the novi 1000 wouldn't you make the same power with 10 lbs of boost on the 1200 or 1220? I understand that the 1200 can support more PSI if you are looking to get in the 400 + range but other than that is there any reason to swap it out? I am only wondering because I have a novi 1000 at 12psi but I am happy being in the mid 300s and if I got a 1200 I wouldn't want anymore than 12 lbs.

 

The 1200 flows much more air. It is a big upgrade from the 1000. 10 psi is not 10 psi. A tiny greddy turbo kit at 10 psi can make around 280-300whp. A larger turbo at 10 psi can be well over 400whp.

 

12psi with a N1000 getting you mid 300's but 12psi with a N1200 will get you low 400's at 12psi.

Everyone always talks about PSI PSI. GUYS PSI is wrothless!! You want CFM's that's what counts.

N1000= ~850-900 CFM's
N1220= ~1050 CFM's
N1200= ~1150 CFM's
N1500= ~1200 CFM's

As you can tell yes all blowers will make 10psi but one will be moving "say" 500-600 cfm's and the other maybe also making 10psi but is moving "say" 900 cfm's. Both blowers maybe spinning at the same speed but one is moving ~30-40% more air.

 

That makes sense. However is there any reason to switch blowers
(or turbos in the case of a turbo) if you are already at your power goal? I was shooting for mid to high 300's and that is currently around where I am at.

Also, is there any reason company's make small blowers and turbos? If the bigger ones are so much better then why are the smaller ones made? The novi 1220 seems to be a lot like the 1000 but the prices of them are all the same so I don't see it being much of a cost issue. I'm just trying to understand why and if it is worth it for me to swap mine out for something else.

 

The 1000 is an older model. They upgraded them over time to a more efficient blower.
Smaller turbos can build boost quicker so depends on power goals.
If you are at your power level goal than just leave it alone. No need to spend money if you don't want more power. The upgraded blowers can make more boost lower down as well since the blow more air. So not only will you get more up top you will get more through out the entire rpm range with a better blower.

 

At the end of the day, you'll get more power under the curve with a 1200 as opposed to a 1000. So as a performance gainer it will be better and make more power all throughout the rev range.

 

Also the reason companies made the kits with the N1000 because when comptech first designed the kits all there they had was the N1000 in that size range. The N1000 was then discontinued by Paxton so Comptech had to upgrade inorder to keep making there kits. SOS has been working with the Comptech kits on S2000's for a long time and then later made there own kits. SOS's kits are just a improved version of the Comptech kit so they also went with what was tired and true but because the N1000 also was discontiued they also went with the 1220 and later made they N1200's and N1500's a option because people wanted more and they were PnP for the SOS kits.

That is why the N1000's were used. (this is just what I gathered from reading the web)

 

i also have an n1000 set up with aftercooler, by switching to the 1200 unit would there be anymore added heat?

 

I understand why the the 1200 is superior and flows more than the 1000 and provides up to almost 100whp advantage over the 1000. Talking about CFM and heat bring me to the question of how much the little water intercooler flows and its effectiveness. I was SC'd for a year and looking at little exchanger I wonder how much will negate the advantage of the bigger blower and how much the 1200 will benefit from a higher flowing exchanger unit. Not to hijack the tread but will like to know if someone has experienced with bigger water/air exchanger. Looking at intercooler specs the novi 100 at 900cfm should be over 400whp easily.

Example of an intercooler spec.

# Core Size, 10.5" X 24" X 3.5"
# Overall lenght 34"
# 2.5" or 3" inlet
# 3" outlet
# 1000 CFM flow rate
# 666 HP efficient
# less than 1 psi pressure drop

 

Just upgrade to a larger front mount heat exchanger. Will cool much better.
