New power plant Option

[gafernandez]

Decided that the turbos are to much trouble so how do you make up for the turbos? Only way possible with displacement. I have been able to fit a V8 motor in the Noble/Rossion

[gafernandez]

Some of the answers. You are right the current gearbox will not handle the torque of the LS motors but most importantly will not fit. I found that one of the F40 gear boxes is a direct bolt on to the LS motors and is readily available. Goal is to make 450bhp which as already been mentioned is very easy with these motors. The transmission can be upgraded to hold 590 ft-lb of torque. I believe that should handle anything the chassis can handle

Everything is progressing very well for only being 3 weeks into the project and one of those weeks being a holiday week.

One of the major design goals was that it had to fit without any chassis modification. The first goal was achieved.

The other major goal is that installed entry level package to cost less that 20000.00 Dollars.

I am only working on the transverse layout i believe the longitudinal layout would be a mistake in this platform because you are starting from scratch if longitudinal is you goal start with an ultima GTR not a Noble/Rossion.

On the LS3 it would be great if it were as simple as that. It is a special ls block

Fuel tank is in the same place.
Exhaust is very easy the hard parts has been the accessories.

Yes we are keeping A/C

Some updates for today

exhaust concept

muffler from concept to reality

cold air intake

Why am i doing this mostly the turbo issues "heat", parts availability for the transmissions, and just overall complexity of the V6 turbo power plant.
The GM LS and the GM F4O transmission are readily available and very reliable.I also felt it would be a great retrofit or new car option if I could figure out how to do it with out modifing the chassis. This is going to be a direct bolt in option.

The main reason, I was told it could not be done. Well that is all it took to push me over the edge

[gafernandez]

Weight the answer is surprisingly similar.
The new motor is 60lb heavier but the turbos and intercooler way 83lbs not including all the hoses and clamps.

I did base line the weight of the car before I started so we will see when it is all done

[gafernandez]

I will be happy to give you a ride. Come visit me in Dayton Ohio in the US.
Would love to make a UK version any volunteer's

[gafernandez]

Yes but why would you want too. I can make 700bhp comfortably or push it a little and make 800

[gafernandez]

The Rossion and the noble chassis are the same and I did not extend the chassis. There are absolutely no mods to the chassis. I is a direct bolt in

Interesting. How are you using the solidworks simulations in this case? I have'nt done any fluid flow simulations but would be very interested to see how accurate and essential this has been in your development.

The simulation is only as acurate as the flow model you setup. We have found that it is fairly accurate.

[gafernandez]

I can make sure that happens

They go in the back corners in the diffuser area. There is a large expansion chamber before the mufflers.

Great ideas, I did a lot of research on the electric power steering pump and found it is very loud if it is not controlled by the ECU.

The electric water pump is an option but not very reliable from my research.

The water pump and power steering pump reside in there original location so i did not have to design brackets to attach them. Once all the brackets are finished i will show the actual assyembly

[gafernandez]

I have been quite because there is a lot going on but it does not look li much here is a few pic's. Motor is on the motor mounts and ready to start in two weeks, waiting on parts to arrive. ECU upgrades 1) throttle by wire 2) E85 sensor 3) speed sensor 4) A/C controlled by ECU 5) Fans controlled by ECU 6) alternator controlled by ECU. What this all means is that engine will not stumble when they all come on at one time
