Its a legitimate way of making horsepower but difficult to use as an aftermarket add on especially on DI engines




My other car is a 2013 Abarth 1.4L Turbo and I enjoy it a lot! But personally for a driving experiece nothing beats an NA well tuned, no delay of any kind when you stump on the throttle! Of course if you have done your homework right!

Well, I do respect everyone's choice of swaps. I'm with Patrick, 3800SC will never be my choice because my personal line of thought is that if you need boost to make power you have no clue of what you are doing. Then again I don't mean you don't know what you are doing. That is your choice and I respec that, as a matter of fact I'm subscribed to you channel because I like to see different Fieros. I'm all about sound, from idle to WOT! The 3800SC sounds "to me" like a HURT duck asking for help. It has no personality or aura.
I respect your choice, you like the wining sound drowning the displacement of the 3800; I respect that 100% because its your choice.
I like Green, you may like red and someone else may like Brown. To each their own and we should we respect eacho ther choices!
Me love you long time!
PS. I gave you thumbs up on YouTube!




Here is my take on the anti-boost folks. You know, the no hair dryer for me - or all natural, no boost crowd. I respect a high revving, high HP engine BUT, we just happen to be stuck (in many parts of the US) with atmospheric pressure of around 14.5 psi. You can't feel it or see it, but it is there and it is what forces air into the NA engine. Why not increase that pressure? If you just about double the pressure from 14.5 (from mother nature) to 28.5 with the help of the trusty M-90 you get just about double the power. Just about because the engine does not flow "double at 28psi from what it does at 14.5 psi and it does take HP to drive the M-90. I think of it as a very smart way to make power. Otherwise you really have to either massively increase the displacement (to get any low end torque) or REV it to the moon - which is much harder on rotating parts and valvetrain. I totally respect a nice NA engine and what you have done with yours - but I prefer Boost. Sound to me is a secondary consideration. I think it sounds fine but cannot deny that I have often thought to myself (a solid GM guy) that through the years the engineers at Ford have always made the mustang V-8 sound pretty sweet. Anyhow, if it has a motor and is pretty quick - I am a FAN! Cheers. PS, I appreciate the thumbs up (:-) !

Oh my..

You respect everyone's choice but you disrespectfully call them clueless in the next sentence.

You can't talk out of both sides of your mouth.

Good video and narrative.

I've built several of these over the years and they are everything you say.

But, not a fan of the blower whine right behind my head, so my choice is a lightweight V-8.

Keep up the good work!

Regarding modifications to the intake and heads, etc, anything you do to a naturally aspirated engine you can also do to a boosted engine.
It is not necessary to make a choice between mods or boost.

As far as how easy a modification is, that is relative to how much knowledge/experience you have.

When I was 17 with my first car, I was happy with myself because I was able to do a stock brake pad+rotor replacement. Now that has become a boring chore. Recently I added boost to my mostly stock Fiero engine, and I learned stuff.

Wherever you are on the learning curve, if you try something new and challenging, you will learn. If you do the same things over and over again, you will stagnate.

While perhaps not the best engine choice (personally I prefer a 400 bhp all alloy 2.0 Ecotec - more available up to around 600 bhp_) I think that the 3800 is a valid option, albeit a rather dated engine today.

Thank you! I love your comment !!

I thought that the 3800SC is a dated swap and it may be but I have looked at some of the 1/4 mile times on cars that have the LFX engine and they are not particularly impressive. Mid to high 14 second runs seem to be what the LFX powertrain is capable of and that DI engine doesn't take well to mods.
Here is a video of the LFX vs the LS4 Impala.

Those quarter mile times are achieved when the LFX is installed in a FWD boat, right?

Not exactly the best type of car to demonstrate the LFX's potential.
