Who makes something similar?

That's tough. In Vegas we're approaching 115* ambient temps in the summer. I've been wondering how feasible it is to boost an air-cooled here without an intercooler. It seems like we would be very boost limited here unless you choose to substantially increase the technology, i.e. intercooling, efi, igntion control etc.

Water/Alcohol Injection works very well for lowering intake temps.
I inject 3.0 gph into my engine and it lowers my intake temps 100 degrees.
I can run 20-22 lbs boost and have 135*F IAT's injecting the Water/Alcohol mix 50/50.
I run two nozzles staged at different boost levels to keep from adding too much at low throttle settings and it has worked really well.
Here are my two Hobbs switches and two solenoids for the different boost levels. The 1.0 gph comes on at 4.0 lbs and the 2.0 gph comes on at 9.0 lbs.
I have also added an intercooler recently and with the two combined it gets my intake temps back down to under 80*F in spring and fall at over 22 lbs. boost.
With a 1776 you can probably use a 2.0gph nozzle set to come on at 6.0 lbs up to 13-15 lbs boost. You will need some ignition retard along with it too.
The critical area is mid rpm high load about when the turbo hits full boost.....for me it's right around 3500 rpm in third gear. That is where you need the max amount of water and ignition retard if the water doesn't take care of it all.
I'll never run another carb again since I've gone to FI.

Lot's of folks go with a draw-through setup in those desert climates. The natural charge cooling effect of sucking fuel through the compressor housing seems to work well. I have not personally tried a draw-through setup yet, but have heard of more than a few who really enjoyed how they drive. Race fuel would be required for 'high boost', but how high is too high depends entirely on the build and the tune.

Nice old school setup! I noticed you have your intake t-ed instead of radiused. |

What the hell is that? Definitely NOT the route I’m considering.
Would your deck lid close over that? 😂
Jk, I know it’s badass but I wanted more of a turbo sleeper idea. |

I'll tell ya 'What the Hell it is" It's a Viper/Vette/Mustang/Camaro /Mopar ,,ass kicker and yes the intake is T'd for a good reason

Right on!  Your engine is purrrdee! I say it often, but I love a big ol' turbo and exhaust hangin' out the back of a bug or ghia! |

Thanks, I saved up parts for a few years to build it, was going N/a with 48 IDA's but my son kept telling me to go 'Turbo' he was right  no more shifting at 8000 rpm's, no more close ratio trans, first time I built it with a w120 cam,, but it wanted more, way better with the FK10 the w120 left a lot of
power on the bench/table

If you have access to E85 its a game changer. I've been up to 20lbs of boost with no intercooler on E85. Just need big enough injectors and a bullet proof way to retard your timing.

Ha, you would be happy with 100whp for like a week, maybe two...then you would want more.
Its not tough to hide the setup under the deck lid with a blow through. With a draw through, yeah, its a little tougher, but buy the CB hideaway header or something similar and you can do a closed decklid build easy. I can close the decklid on my '74 standard with no issues. The only issue some have is draining the oil from the turbo. Put a deep sump on and have an inch or two of slope from the turbo drain to the deep sump and you're good to go. |
I was going to ask that question, where do you drain the turbo? Could you use a scavenge pump and dump it back in the block ? I’m new to this turbo stuff. |

I’ve not done it but I try to stay plugged into what them crazy LS boys are doing and some of them with remote and or rear mount turbos do exactly that. But the rub is the scavenger pump has to be even lower than the turbo. In a VW it’d probably be scraping the pavement

As is propane with it's 120 equivalent octane rating. Gave up on gas, 18 psi, no intercooler, wheel spin at 70 mph passing traffic! |

Truth. I'm filling up twice a week when I daily drive it, and I've got a 10 gallon tank.

Gas mileage will suffer significantly with E85. But most will focus on the tradeoff.
