Hi Guys,
Might be in a position to fit some 24 /26g turbos some time early next year.
I am not saying too much at the moment as the person who might be selling is also moving up the power ladder.

what would be the difference in power with K24/26g and:

A. Full Markski blow through system intakes on top of 4 inch I/C's etc etc OR
B. Large bore in intakes with Markski's 4 inch I/C's etc etc

Hopefully Mark will be able to give me the pro's and con's of both.

I ask, because although I like the idea of the blow through system it means the Air filters sit on top of the I/C's. In Scotland it rains a lot and we have a lot of $hit on the roads. I worry about the level of water and muck getting on the Air Filters through the air scoops.

Any one with some experience on this, I would appreciate it.
Cheers
Frank

 

the filter sits above the IC.. nothing gets in there.... same approach as when you have a stock filter. sh@t gets in there too...

btw I do not understand what you mean B. by large bore?

 

Hi Mark,
I meant the larger bore piping instead of the plastic stuff that comes from the air filter.
Its mentioned allot on here instead of blow through to get more air to the Turbo's.
I dont want to mention too much at the moment but would talk freely to you by PM.
Not that its clandestine, but you know the person, he knows me and I dont want to talk about his affairs without his permission. I think you are going to do something special for him anyway. So I might be in line for his stuff.
It was dirt and moisture coming form the I/C air scoops that worried me.
cheers,
Frank

 

gotcha...

the advantage of a blow thru maf is that you can tune for the higher load... whereas the stock maf tuning is sort of blind calibration.... it still works but imagine that most of the maps are written on a engine load vs rpm table... thus a car with 600 rwhp will produce lets say 240 engine load... the map goes up to only 190... thus you cant dial in timing and afrs correctly... you can get close but you have no control thus let say you want to lower the timing by 5 degrees at 220 load and you cant. you actually do it at 190.
whereas with the blow thru, the load numbers change.... and to get to 200 load you need usually a lot more boost and power.... so you can control the tuning better because your within the range....

both approaches for you will work... that turbo is not that big of a deal... lol
the stock maf works with our 3.5" ICs the blow thru with our 4.5" ICs..

you will be fine either way....

i dont think a blow through setup is needed for those turbos, as with larger turbos your choking them without the setup IE 20g's 3076's gt35's ...

of course do the larger inlet piping, but if you ahve the money for the 3000$ blow through it wont be your restrictive place in your intake. Do remember the Blow through is not as good for lower power cars as it is for the high power cars that really need the big pipes.

it really depends on where your goals and uses are for. if you want 800whp go blow through big turbos and turn the boost up hoping the heads stay intact =)

 

Ist not just the pipes.. Todd originally used to do the blow thru on 18gs as well when other turbos were not an option...
You can dial in the car better.... you have workable tables vs blind calibration....

but for him I agree... injectors, the bibber piping, ICs, decent exhaust and he's fine...

They are K24/20g's not 26g's

Mr F

 

Hi I stand corrected just checked the e-mail They are as you say K24/20g turbos. I have been out in the car and what can I say....excellent with not too much lag either.
Frank

 

Hi Mark,
A good explination as normal, thanks.
The turbos's are K24/20g not 26's.
Still, so long as there are not dirt issues with the filters on the Ic's I will probably go with that set up.
Thanks.
Frank

 

Well, if they are 20g then you'll be better doing a blow through I think...

 

Frank, the issue is also going to be heat the turbos generate, hence the BIG I/C that he uses and the blow through system.

If you dont use the blow through, to reduce the lag you will have to have the rear intake anyhow. Trust me, this is a ***** to fit to right hand drive cars!!! I was billed 27hours for fitting plus refabrication (engine out).

Go blowthrough...

Mr F

 

I've got 20g's with the blowthrough. Don't do them unless you are going to spend the extra money for the blowthrough. Its the only way to get everything out of the turbos.

 

for 20g's you need the blow through, big intercoolers, big fuel system, a clutch that can handle the 700whp.


nice sig Ben i like the last part =)

 

Thanks to everyone,
Its blow through then. To be honest it was most likely anyway, as the kit will be complete as a package.

I will post later on once things are sorted
Frank

 

Yes now seeing that they are 20gs go with what works....
