F355 with fuel tank up front like --porsche 911

Hi 355 guys
i have been working on removing my existing tank in the rear --&--putting
another fuel tank up front like the ---porsche 911

the tank is made of 1/4" thick aluminum with baffles +30 gallons fuel +
52 pounds the tank alone weighs---go figure complete weight up front

i also installed two 16" fans in the space where the old tank was
f355 handles better than before==nice weight balanced=around corners

now i have easy access to the engine ===anytime==i am so happy
no more engine removal===no stress==i did it all=by my self=no help

One of the reasons the fuel tank is in the rear is to put it closer to the CG so handling does not change as fuel weight changes. Cantilevering it up front like that will make for a pretty good shift in CG as fuel load changes and is likely to affect handling.

Center of gravity all fine & dandy

Hi guys

i can say for sure this 355 handles a lot better than before with cg
the front was too light --now it is well balanced all around
nice cornering--not slipping & sliding on wet roads-handles with more
confidence---i feel very good in what i did for the f355---ferrari sits nicely
@ 80-100 mph on i-95--squats nicely --with this --rear stance--

krome

i can clean my complete engine anytime -anyplace-i choose--running cool
i also have 2--16" fans cooling --alternator--headers-engine-oil cooler etc.
Any mechanic can change my timing belts for--- $100 bucks

+1, and what the other thread I stated might be a problem too is steering with heavy weight front of axles

but

I understand his desire.

Krome, bravo for taking this on and making it work. Did you use a racecar fuel cell for your new tank? It would be interesting to know more about it.

High mileage, low compression, and missing on a few cylinders.....just like my cars.

I like the idea of being able to get to your engine. However I am concerned about a front end impact. A bladder would be nice.

I understand the principle of easier servicing.
I equally understand the principle of having more weight on the front.

What I do not understand is the principle of a front end smash and how it may effect the fuel tank and its contents.
Will the tank rupture and spew its contents all over the place?

An interesting conversion but at what risk?

I worked on a 355 Spyder that was own by Shaq, the removed the convertible top and fuel tank, put a racing cell in the front boot, and notched the firewall for extra leg room. It was great for him, but became a worthless bucket of parts after he was done owning it.

Fuel dropping and spraying will definitely be a concern with the tank's location and construction. Having that in front of my face in a Spyder is probably not my favorite idea. At least in the 911's there is 2ft. of unibody, steering and suspension to crush before getting to the tank. Having a bladder inside would have given me great peace of mind.

There are a number of production cars with fuel tanks that aren't greatly protected though. I believe the Pinto was one of those?

Krome, what you've done is very innovative, but by putting a self fabricated fuel tank up there that has no certifications at all, you've left yourself (and your family/estate) wide open to a huge liability risk.

I hear what you're saying about enjoying the time you have left, and if you ever rear end someone and that tank ruptures & explodes, you probably won't be around to worry about it, but if someone else is injured/killed, think about the expensive mess you've left for your family & estate to clean up.

I would respectfully suggest you at least consider replacing that tank with an ATL or other certified fuel cell.

I with you on John this point. The idea of a rigid, non-purpose built fuel tank is very unsettling. The risks of personal injury are way too high....

You need weight up front for wet roads on f355

That's why you need more weight up front & support for wet roads on f355

this ferrari is well balanced now with 250 pounds over the front wheels
does not skid on wet roads----before this f355 was too light on the front
it will slide around on wet & slippery pavement

now it sits & handles great around any corners or wet roads

got the picture !

As I said in the other thread, it appears that with the fuel tank removed, you can access the engine. The firewall has to be modified but the point being the fuel tank is removed. The way I see it, if you make some changes so that the fuel tank can be dropped, you could access the cam belts without removing the engine. No need to screw up the handling characteristics of the F355 and you can keep your trunk. For anyone looking to get around the engine out, I'd spend some time trying to do a quick fuel tank drop. Krome is already committed to this method and I doubt he would change it now.
