That's awesome #'s on pump gas. What boost level do you run on the green with pump gas? I plan on swapping out my FP ported Big28 with an internally gated green in a few months. I think the FP green has been well proven over time. It's a great street/strip turbo IMHO.

If you spin your tires, it will throw the G-Tech off. I have one as well, and I can never get consistent readings with it. I think at 15 psi 250 to 260 hp at the wheels is about right for a Big 16g equipped 1g. I have seen 240 hp at the wheels on a 2g Big28 equipped car at 15 psi. 15 psi isn't...

That's cool. Thanks for the info, and no.. I don't think that I would be to interested in shooting flames out my pipe LOL. Peace!!

I would definitely go DSMlink if you can afford it. DSMlink is the shit. I had already purchased the S-AFC before the DSMlink had even come out, but if I had it to do all over again I would go DSMlink. It just pisses me off that everytime I go to buy something the very next week somebody comes...

I use 550's and a walbro 255lph fuel pump with my FP Big28. Although You can use a 190lph fuel pump. I use a walbro 255 because I didn't want to have to swap fuel pumps out again, if on down the road I decided to go with a bigger turbo in which I plan on going FP Green and 660's.

With that turbo you should definitely go 660's. I'm sure you would max out the duty cycle on 550's. 550's are perfect for FP Big28's, 16g's, and big 16g's, but not for a 50 trim.

I like my FP ported Big28 so much that I'm now thinking internally gated FP Green sometime in the near future.

I say anywhere from 320 to 360 hp @ the crank depending on your boost level, and tuning. I believe 16g's will support around 360 crank hp if I'm not mistaken.

Thanks fellas, I really appreciate your help. I guess I will be swapping out the RRE MBC. It's a bleeder type valve, therefore causing alot of spike, plus it didn't come with a mounting bracket, which sucks. Thanks again!!

That is to sweet KRAZYKOREAN. I definitely like that! I like the idea of being able to adjust boost from inside the cockpit. I appreciate you taking the time to show the picture as well. You have a nice looking car. Peace!!

Yes!

Hmmm... what a mature response. I guess that's to be expected from a young Korean BOY.

Anybody else?

That is an interesting idea, but the only problem I see with that idea is the vaccume hose would be to long, therefore causing excess boost spike.

That sounds cool. I just wished you had a picture as well. Thanks!

I'm currently using the VDO boost gauge and the only problem that I have with it, is when the car is turned off the needle on the gauge doesn't sit exacty on zero, it rests slightly or one bar below the zero, therefore I'm really not sure if it's reading accurate or not when I'm boosting.

Ok guy's I'm tired of using zip ties to mount my RRE MBC under the hood in my engine bay. I'm looking for another method thats more clean, and or neat looking. A while back I saw a picture of someones MBC on these boards that was using some sort of bracket to mount there MBC to one of the...

Well... that's all I'm really worried about is if it's leaking boost or not, not vaccume. My vaccume seems to be fine. Is it boost or vaccume that you are referring to? When I'm at idle I see around 18 to 16 IN HG and or vaccume, if that is indeed what your talking about, I'm not to sure. If you...

I get 1.5 psi of pressure drop, and as I said before that is the amount that most fmic's are going to lose anyways.

I agree, it is not the best fmic out there, but it did support about 450 crank hp which is more than what most of the people on these boards will ever see. Nuff said!!

Well... mine doesn't leak. My 1g bov that I used to have did, hence the reason I switched to a GReddy type-s. I have about three threads showing on my type-s bov and I'm running 20 to 21 psi of boost with my Big28, and it holds boost so much better than my 1g bov did. What did you use to stop...

As I stated earlier Larryd made 380whp, roughly 450 crank hp with an AGP L2R and the big GReddy fmic at over 25 psi with supporting mods, so I think it's fair to say it does a good job, not the best but good, and last I remember an AGP L2R is considered a large turbo.

How do you know that all GReddy type-s bov's leak?

My old T-25 use to glow red all the time after hard runs, and so does my FP ported Big28. You could only see it during the night. It is perfectly normal for a turbo to glow red after running your car hard.

I get about a 1.5 psi drop in pressure at the most, and that amount is just about normal on any fmic that you are going to purchase. If your going to purchase one brand new, you might as well by one of the better ones out there such as the Indy Race Core unit or the one from Victory Performance...

Agreed! I'm using the big GReddy fmic with no over heating problems at all, even with the AC running full blast in 85 to 90 degree heat, along with 70 to 80% humidity.

I'm currently using the Big GReddy fmic, along with my FP Big28, and I have no over heating problems whatsoever. I know it's not the best fmic that's out there, but it does do a great job. I purchased mine used from Larryd awhile back. He dynoed at 380whp with an AGP L2R while using the big...

Only you will be able to decifer that. Remember every car is different when it comes to tuning, even if you and another car had the exact same mods the tuning will differ 80% of the time. You will have to just keep tabs on your timing, egt's, and O2's, to see if you can run 20 psi on it. Good luck!!

The consenus is about 400whp for the 2g's, and 450whp for the 1g's. 1g's have beefier rods. I have seen 424whp from a stock internally 2g, although this individual was running arp head studs since he was running over 25psi of boost. 25psi is generally where the head will start to lift because of...

Mods are in my profile. I'm running a ported FP Big28 @ 20 to 21psi. I have my plugs gapped @ .028, and I use a Craftsman feeler gauge to gap them with.

The valve you are referring to is just called a check valve.

Agreed! The factory rates it at 215 crank hp, and every car mag that I have seen has dynoed it at 223 to 224 whp, which comes out to about 260 hp at the crank if you factor in a 17% drivetrain loss for a fwd, so yeah I would definitely say that it is very underrated from the factory. I'm just...

Also what 28 series turbo are you referring to? There is a difference between the old style T-28 which is rated @ 320 crank hp as comared to the latest FP Big28 which is rated @ 360 crank hp. Example: There is a guy that goes by Hor over at DSMTALK.com that ran a 12.4 @ 109 in a 2g awd with just...

I use a mbc and I have my boost set at 20 to 21 psi all the time. Just because I have my boost set that high doesn't mean I'm constantly running that much boost everywhere I go. I control how much boost I'm running by how much pressure I decide to put down on the gas pedal. That's why you need a...

A 2.5" exhaust has run 11's in the past! Search around, there are plenty of threads talking about exhausts systems and such. I myself run a Buschur 2.5" dp, 2.5" race-pipe, 3" Thermal exhaust to help support my FP ported Big28, and it is plenty. Good luck!!

Yeah I know what you mean, I get boost spike as well. Mine will spike to about 24psi then level off to 20 to 21psi with my ported FP Big28 and RRE MBC. It gets on my nerves sometimes.

As with you I'm not a teenager either. I'm 34 years old, and if your trying to make power, it's all about flow my friend, it's all about flow. Test-pipe all the way!!

Yes... it is very normal on hot days for your boost to DECREASE a few psi, just like on super cold days it will INCREASE a few psi. You just have to compensate for it on your boost controller. Good luck!!

LOL! LOL! That's to damn funny. You just made my morning. That was just what I needed to start my day off right, a good horse laugh. Thanks LandoAWD!

What is the difference between a "motor" and an "engine"?

Nice run Wikkedson!! Those 104mph traps are very good to just be running 16psi, with stock 450's, and the stock smic. I run 21psi on my ported FP Big28 on the streets, and let me tell you this, you are in for a real treat when ever you upgrade to some 550's and a fmic, and crank the boost on up...

I'm talking crank hp not whp. So it would be about 15 to 20whp give or take. I have no dyno sheets to prove this. I don't need any to prove myself, no pun intended. Just call up one of the vendors such as FP and ask. Hell... Brian at FP run a 13.0 @ 115 with the Big28 in his GST. He had a 1g tb...

I don't know why people rag on the GReddy big fmic so much but it's not that bad. Yes it does have longer piping, and the piping routes in front of the fmic, I do know that. But it works damn good for me, and has for others. I have no problems with mine at all, and it cools the charge air very...

NP! I'm not sure if there is any fmic's that will bolt right up to it, like I mentioned earlier the only way I know of, is if you have an elbow welded on to it, or if you could have ordered it with a rotated compressor housing, other wise I'm not to sure. Somebody feel free to correct me if I'm...

The big GReddy fmic piping routes back to the stock location. Unless you had a elbow welded on to the 20g it won't bolt right up.

NP! You will meet your goal, it justs takes a little time and patience, and above all money.

No...the Big GReddy fmic does not require a slimline fan. I run the big GReddy fmic, and I have no problems whatsoever, even in 90+ degree temps.

Derek... I'm not quite sure if you mean 450whp or 450 crank hp but with the above mods that you mentioned a FP Green should be very adequate in obtaining a goal of 450 crank hp. 450whp is another story, but possible on race gas with the right supporting mods and some GREAT tuning. I'm pretty...

Josh... I have two more VIN#'s for you to run dude, and I promise I will leave you alone. One is for my 98 Blazer LS, and the other is for my 89 Oldsmobile Cutlass Supreme which is my beater to keep miles off of my GST. Here is the one for my Blazer VIN# 1GNCT18W5WK154713. Here is the one for my...

I have seen about a 30 to 40 hp increase when a 2g has been out fitted with a 1g tb, intake manifold, and head with a 14b. That is a significant amount IMHO. I plan on doing the same with my set up, with the Big28. Good luck!!
