TDO5H 20G vs. Big28 Killer

[DCsGST]

OK, I'm thinking about upgrading from my BIG28 Killer (550 cfm) to a 20G and just want to know how big a difference the TDO5H 20G will be compared to the killer. If it doesn't flow much more then I don't want to waste my time with it. I'm looking for 350-75 whp, and the killer is only rated for 380hp at the crank.

Thanks for the info in advance.

how is your current t28's condition, i might be interested if you decide on getting rid of it.

I have seen the 20G rated between 575-625cfm. And power rated from 400hp-450

I can tell you that the TDO6H was a great turbo. Suprised me. The tdo5h is not the only option you have to get. The 6H wheel is only an extra $100 and is far more efficient.

The reason I'm looking at a TD05h 20G is because it's internally gated, and I can get one used for around $650.

So is my 6H, but it cost more than $650. Is the 20G in a 7cm housing?

Yes, I believe so.

Then go for the 20G. You won't be dissappointed in the power it will give you. Especially in the upper range. It will flow more and be more effiecent at the 22-26psi range.

Well, I won't run that high often, I don't wanna blow a head gasket anytime soon. I was thinking 15-17 psi daily, 22-23 psi race.

You will still flow more at the 15-2X PSI level with the 20G.
