for real, i have to deal with that shlt everyday! brake fluid is really mean shlt too.

Inlet is in the rear. There is tons of room for a filter. Later on if I get a big cowl, I can move the filter box near the dist for true cold air

GM blower cases are rather bulky and change over the years extensively

The twin project was a "can I do it" rather than the perfect power adder. The design also leaves room for upgrades to a M112 or aftermarket blower simply by moving the mounts and outlet hat


Ill look into that

in for some more on this, very cool build!

iTrader: (2)

cool built....actually I have been thinling how cool it would be just to look at.......but then again either nobody is doing it for a reason or somebody did it (you!!).

I am saving this stuff for a "someday" project

So what kind of effect would these show on a stock 5.7L LS1 ? or would I need to change things around to reduce compression.

If u had a Ls1 and where looking for a couple stock SC what year cars woud you keep an eye out for on ebay or JY ?

Pocket

iTrader: (24)

My blowers are from Ebay. They are the Tbird units

Im not sure how these will work with a L98, much less a LS1. Future plans 'may' include a iron 6.0L, but dont count on seeing that for a few seasons if ever

This isnt a project for the feint of heart

IDK how he was inspired by him? that was done before this project started.


It inspired me though.

RED_DRAGON_85

it was a joke

DUDE! And you went and criticised my alternative LT1 swap while putting this thing together?

It's almost identical in concept to the setup I was designing for my friends Porsche 944 (minus 1 blower) before he decided to do an LSx swap.

We were going to mock everything up out of MDF then mill the bracketry out of 1/2" aluminum from the scrap metal store. Put it all together like an Ikea end table lol. Before that it was supposed to go on my Mazda but I went turbo instead.

I didnt read the whole thread but why wouldnt you use a blower kit for the 1G sbc and plumb it with EFI? The smaller (122ci) kits go for around 2K. Some porting and fab work can make one of the old school blowers work nicely, an intercooler between the blower and manifold is doable too.

Thats only slightly less displacement than your total displacement, the rear intake and bypass offer some significant advantages over the older blowers but I'm not so sure this setup will put out a lot more power in the end.

Never the less good luck, it's the type of thing I'd love to do for a friend.

ericjon262

got any updates for us pocket?

I think Jon has like less than $200 into this whole project so far, thats probably why he didn't go with the $2000 kit.

Gear lube is the nastiest fluid in a car (especially burnt), barring non-DOT5 brake fluid, because it's only nasty for it's paint eating properties.

Pocket, you might want to look into ABS Powerbrake's electric booster setup. It lets you mount the master on the firewall, and you use an electric hydraulic pump instead of a vacuum or hydroboost. You can remote mount it anywhere, but the closer, the better.

ericjon262

I agree, I was mainly referring to oils in general

burnt gear lube makes my butthole pucker up, sooo nasty.

pocket i got a couple questions for u...

is the Z06 MAF a direct bolt in for a stock GM firebird MAF wire harness? and what is the purpose besides being larger/flowing more air?

and what does your "tuner" state about tuning for this beast? from what ive heard its better to tune with a SD setup than a MAF.... but ive also heard that the MAF is a easier plug and play system and will make it easier since it directly measures the air (not applying this to a forced induction setup). but doesnt the Forced induction change the purpose of the MAF? since its no longer sucking the air under normal atmospheric pressures and the intake is now pressurized? basically just saying now that there is more air per cubic inch vs a NA motor wouldnt the MAF calculations be off?

im planning to run dual t3/t4 turbos and i want to keep my MAF system and tune it. tuning is fun i just want it to work which is why i ask. i love the MAF system and im sure GM figured it was best bc it went from MAF to SD and back to MAF for EVERYCAR STILL BEING BUILT!

Pocket

iTrader: (24)

It is a truck 5 wire MAF. You need to cut the old MAF and IAT pigtails off and attach the truck MAF connector for it to work. It is larger and more accurate

Im confident in the tuners abilities. He suggested MAF for what Im doing, so I put the MAF back on. I read on tech about maxing out the MAF after so many PSI, so I was going to drop it. Hes tuned beasts much wilder than this combo and said MAF was better

We will see

If you are talking about the LS1 MAF, they make an adapter for it so you don't have to hack your harness. I have the harness and a truck MAF if you are looking for one.

ls six

The MAF shouldnt have any limit based on PSI, it might have an effective limit when it comet to measuring CFM at some point but it's your MAP and IAT that are more concerned with boost (IAT for measuring any boost related temp issues not for boost it's self) the only problem you might ever have with a MAF and boost is the rare event of the housing failing.

It's rare for MAF's because of the shape but VAF's as used on older Toyotas and Mazdas commonly fail above 15 PSI.

Pocket

iTrader: (24)

It uses a 0411 harness that I built. I added the truck maf connector a long time ago. There is no hacking of the harness. Come to think of it, most people think its stock

Im going to do this build now. I saw you said that the GM units are bulky but I cant find any T bird eaton m90s at my local yards.

MORE PICS PLEASE.

Killerzracing71

In the pics did you already relocte the brake booster?

Also what are the dimensions of the T bird M90. I have a copy of the GM version (well atleast thats what I think it corresponds too)

Pocket

iTrader: (24)

Deleted it attempting a manual brake conversion. Even with the additional mechanical advantage from moving the mount point upwards, the brakes are ridiculously hard. Im going to either build a remote system or incorporate a tiny import pancake booster/master

why not use hydroboost brakes? get the booster from an 94-95 chevy astro van and the master cylinder from a 4th gen f body it will bolt rite in place and is a lot smaller. the only part that needs to be modified to convert to hydroboost is the linkage. the one from the astro will be 3/4 of an inch to short. but that aint hard to fix.

Pocket

iTrader: (24)

Distance from the firewall to the master flange is what Im trying to minimize

Hydroboost systems are smaller in diameter than vacuum boosters, but generally very similar in length. Also, I dont have a PS pump any longer

duckmanquacker

Am I seeing this correctly? Are the plates at the front of the block which hold the SC's also your front engine mounts?

Pocket

iTrader: (24)

Plates mount to the heads and block. Yes, they double as motor plates

Eventually they will support the engine alone, but currently the stock rubber mounts are still in there

RED_DRAGON_85

if you get larger diameter brakes, and specify that you want the piston diameter in the calipers to be larger than stock, you shouldnt have any trouble stopping.

many people in the pro-touring scene run non-assisted brakes with no problems on a semi dd car.

you will need a new master cylinder, and new calipers at a bare minimum.
the calipers from a power assisted car will not work.

if you are trying do do it on the cheap, start raiding junk yards for parts from older 80's cars with non-assisted brakes.
