halfway through turbo install

Not to mention detonation......(can you say grenade?:yikes a pressurized intake charge requires precise ignition timing, no cylinder carbon deposit hot spots, and generous octane levels........superchargers are better suited for the racetrack........

All true! I was referring to the biggest drawback for superchargers on small engines. You could double the horsepower...but use it all up driving the blower. I agree that thay are better suited for the racetrack. I've sat behind a few of them in my time.

Not to beat this point... but if they didn't work so well, wouldn't you have been sitting in FRONT of them??? :roflblack:hyea:

I'm old. Front-engined dragsters are the only kind I know. You haven't lived until you've experinced a blower explosion four feet in front of your face! :roflblack:

I had a DPS go out 4 feet in front of me....Does that count...:roflblack::roflblack:

I've opted to seek a solution from military surplus for my RT, which entails removing my rear hard case covers and installing clusters of JATO (Jet-Assisted-Take-Off) bottles, similar to that seen on legacy bomber and transport aircraft for short-runway lift-off. There's a blank on my console switch panel, where I can put the ignition switch. Here's a larger-scale demonstration.

:roflblack:

That's Fat Albert! I love that Demo! Always get a charge outta that! You may want to strap ion for that one! :roflblack:

There is a bolt-on Super-Charger solution for my V6 Monte Carlo that is extrememly good. However, 3.8 litres is not really a "small" engine considering what we are talking about here! I think for this application a turbo would be the better choice. Congrats Altonk! Your project is really starting to take shape! :thumbup:

I've seen it many times; It is very dramatic. Never been in the seat though! Now THAT would be an experience!

[SpyderWolf]

Altonk, have you gotten any testing rydes in since completing the install? How long is it supposed to be before the other parts arrive?

turbo vs supercharger

Turbos work on small displacement engine's. Superchargers work on large engines.

Is 3.4 litre engine considered large?

I have a TRD supercharger on my Tacoma 4x4.

Due to automatic trans never get to the peak performance, but a whole lot better then stock.

It's Done

:2thumbs: everything went smooth
Don't have logging up yet so I set it stock boost and rich to be safe

Did some riding

Twistys - wow there is some lag but think I can adjust most of it out but keep it above 5k and it's barley noticeable

City driving - safer to just do the grandpa cruise thing and stay outta the boost

Interstate - dude 60 to triple digits slamming

So I did a little number crunching

F1 Mclaren weight to hp 4.1

Dyno results from aerocharger 145hp @ the wheel ~ 15% loss from the drive train 21 hp
Call it 165 hp
Dry weight of spyder 700 + 20 for the turbo

700 / 165 = 4.366

Sypder + mods $ 32k

F1 Mclaren a million two

I can live with out a roof
:clap:

 

[dave01]

The possibilities with turbo's are endless. I used to run a small shot of nitrous to cool the intake charge at high boost and them went to water injection.
This shows what 1300cc's can do.

Oh and I may have to make some lifestyle adjustments to afford my new tire budget

[Firefly]

Sounding great-- how about some video and audio of you hammering on that bad boy?

I remember ryding docs-- and it was great!

 

[altonk]

it was a kinda laided back ride today

tomorrow i'll twist on it

So can you explain the sensation of having the turbo over a stock engine? I know you didn't have much room to really get it on there but wHat does the acceleration feel like? How does the front end behave? does it want to come up or does it settle?

Imagine the speedometer connected directly to your throttle....as you twist the throttle-- the speedometer moves at the same rate of twist......:yikes:


Okay-- maybe not quite--- but really impressive! On docs I found you really better hold on if you're slamming it-- cause it throws ya back. You can hear the boost pressure too---pshhhhhhhhhht when you hammer on it. :thumbup:

Front end isn't going anywhere. What you find is that as you're cruising in any gear-- you can just roll throttle and GO -- no need to downshift.

That's just my take from riding docs---- I'm sure the few that actually have them can give you a more accurate description on what it's like.

Man that sounds fantastic! What a rush that must be - I've never experienced that kind of feel in open air. Had a couple of cars that did that but you are in a cage, ya know? Altonk be jammin, mahn!! hyea:

 

[altonk]

That pretty much sums it up instant power any where to wheel spin
Acceleration rear tire limited
A touch of lag but not much
