1g Holset users LOOK PLEASE!!!

[1glaserfwd]

Just wanted to know which intake pipe guys with larger inlet or holset turbos are using on there 1g. I was going to order the fp 4" intake this morning and it says if your running a maf with the 4" intake it will not fit!! Is anyone running a fp intake pipe with a holset and a 2g maf? If not what are you guys using? Any input would be appreciated!! Cant wait to get this finished should have the FMIC installed tomorrow and last thing is the intake pipe.

Why not just get a maft setup. They are pretty cheap.

I have a custom pipe from filter to hx40. 3"-4" coupler

I have a GM MAS in draw-thru with a custom Home Depot Racing intake pipe. I think its 4" Black PVC.

I really don't want to change my setup over to a maft now. I already have the fmic with all the piping already done. I am surprised there are not more people chiming in on this!!!

Yeah, don't go with a MAFT.

Seeing the size of the intake and comparing with my 2g injen I'm gonna say it won't fit. My injen won't even clear with the 2g maf and no filter

You could go speed density and not worry about a maf at all. What tuning setup are you using?

 

[1glaserfwd]

Currently running a custom eprom chip, my plan is to get ecmlink this winter and go speed density. I wish I could just buy it now but in the process of buying a house this summer and dont have the extra funds to buy it at the moment!! Seems I may have to make something work. I got a PM from a member who says he thinks it will fit with the 2g maf but I was really hoping to have someone that actually is running the same setup confirm it!!

The problem is there really isn't a good intake to use. There just isn't enough room on a 1g to have nice bends. You'll probably need to have one made. I use to run a hollowed out 1g maf can & 1g filter on mine. I welded in a 4" pipe where the 3.5" one was. I then used 2 45* silicone couplers and a piece of 4" aluminum tube. It worked, but it was way less than optimal. You need a big filter for that size turbo. Only running 25psi I noticed about 2psi drop across a 2g maf with no filter, and 1psi across my 1g filter & can....thats really bad, and makes your turbo work extra hard just to make the same boost.

dejon powerhouse makes a 4" preturbo pipe or mas pipe that will fit a 1g.

 

[My1GLaser]

If you're in a pinch for time and money then you can go to Home Depot and get some Black PVC and make your own. I had one for my 2G MAS before I made this one for the Holset. There are plenty of sizes & reducers and angles to make something work. I think the 4" coupler fit over the oval end of the MAS & the fat end of a 45* elbow. Not the prettiest, but I have always preferred function over fashion.

1Ga (pop-up headlights), 2G MAS, FP intake, HX40.

Sweet!!! Thanks justin that is exactly what I wanted to see!!!

What kind of filter is needed for this to work? I know kn sells a 5 inch long element filter would that work or does it have to be smaller?

 

[boost97gst]

I use a spectre filter. Some k&ns are like a foot long. The spectre is identical in flow but a bit shorter so it might fit for ya. Oreillys stock em

 

[bastarddsm]

Still tho, why would you cripple your bigger turbo by a restrictive maf. I went from a severely hacked 2g maf to a maft setup and went from 550whp to 650whp, just by the airflow increases.

Proof?

 

[duckie1098]

I'm using the FP intake, evo 8 maf, and a cobb short filter. About to switch to speed density so I can get rid of the odd sized coupler between the maf/ intake.

Damn!!! Was that in draw-through or blow-through? I assume blow-through, but I hope you say draw-through

I'm sure you did... I will be running a hta71 shooting for about 420whp. I still find it hard to believe u gained 100hp just from switching. I know once u get around 450 even a hacked 2g is a huge restriction but I don't want to go speed density till I get my tune sorted out. I'm very comfortable with maf tuning.

The power was already available, he just let it in and tuned for the new found airflow.

The vibrant filter also works.

Seems like any filter with a 5 inch element or smaller should work than correct? I wonder why fp says you can't use their 4 inch intake on a 1g with a maf. I'm gonna get the k&n most likely I don't trust these Chinese filters, I have read a few horror stories of them falling apart under big boost and getting sucked into the motor

 

[LandSpeed-DSM]

Because the 1G MAS can won't mate up to the comparably enormous 4" pipe.. and why would you use a 1G MAS in front of a 4" turbo?

If you are running an HTA71.. you don't want/need a 4" intake pipe. Big filter sure, but the FP pipe or equivalent is not doing you any favors with such a small turbo and only 84mm compressor cover..
