Turbo Kit from Speed Force Racing
 

Hey all.. just thought I would post this in a new thread just in case some people missed it.. Not sure if this was common knowledge or not.. but being a member of this forum I dont think it is...

I just called the shop in san diego producing this turbo system and they said it's available to the public right now but you need to tune it yourself. They have 2 kits. The one that is available does not come with a fuel management system. The other turbo kit that is expected (how many times have we heard that) to be done in the coming weeks will include fuel management for a few a higher price of course.....

He told me they were going to try and dyno the car sometime this week to get some #'s...

I'll call them back later and see how the progress is coming....


Thankx!

This kit looks complete and ready. Keep us posted davefzr :).

What kinda numbers are we expecting?

Could this be the answer to all of our questions? I don't need the speed but man would I love to have this kit installed. Everything looks good to me except for the price right now. At the beginning of 05 I should be able to spring for it and hopefully the price will have dropped some. If the numbers look good they could get a lot of business sooner rather than later.

I would also like to add that it is a nice kit. Moreover, it answers a lot of questions about turbocharging the 13B-MSP. It appears that this kit uses the stock intake manifold; the S-DAIS remains intact. I believe the exhaust manifold is another issue. From the looks of it, it would appear that the exhaust manifold would be subject to more heat abuse. Overlapping exhaust pulses may build up at the turbine end of the manifold. Hopefully, this log-style manifold won't create problematic hotspots. The stainless steel material may make up for this possible shortfall. If anyone is interested in buying this kit, in my opinion, when there is a dyno chart available, observe the average power gain, and not the peak power. Flat torque curves may also be a sign of a good turbo kit. At least it is complete, because many of us are tired of waiting :).

I hope this thread doesn't end up in the archive section hanging without answers. It's really weird how these turbo projects come in progress and then as we wait for the dyno results, we would never hear from them again. Could it be the results they are getting? Too low for the money? I hope not.

Keep us posted will ya?

Yeah I know.. I hate when threads dont get ended either.. and are just left hanging.. I definitely wont let that happen...

Just a few other notes.. It looks like they will provide a 1 year warranty with their product as well.. thats good news for anyone concnerned it's going to blow up their engine...

Oh.. and as far as numbers.. it looks like SSR who is the company distributing/promoting the product, says 275 at the wheels.. damn... that would be nice....

hey davefzr can you find out if this kit will be available for the a/t?

SSR...the same SSR who had a huge thread that is currently hanging?

This is a project that Speed Force Racing and ourselves are going at together, hang tight for numbers. (It's the same kit)

Are you sure the warranty covers your engine?!?. Usually it just covers their parts...

Yup.. check it out.. they responded....

and I am not sure about the warranty...

Yup, same one. And I have it on good authority that they're still having problems with the a/f control.

Somebody please figure out the a/f control.

No kidding! You know...I'm really not sure why a/f control is causing so many problems. It seems to me that people have figured out how to control it just fine with the piggy-back units. Now, the gains with stock maps have been up and down, allegedly due to variability in the stock MAF sensors, but that's fine....the turbo kits would probably be using a MAP sensor anyway I would think...do they still need to use the MAF? Hmm, well I suppose they may have to keep it in order to make the stock ECU happy, and maybe the pressurized airflow is messing with it? I don't know...I'm just worried that all the problems and delays are not caused by troubles controlling air/fuel but rather trouble with the motor handling the increased power. I don't have any real reason to say that other than skepticism about the "a/f control" answer to all the delays, so hopefully that's not the case...

My guess would be along the lines of yours... the pressurized airflow is messing with the MAF. Maybe it's flowing too fast before you even hit full boost, so the car thinks it's a WOT when it's not. Dunno. I do know though that this a/f thing seems to be the problem most FI manufacturers are running into.

No we aren't having any more problems, we got some base runs on the dyno this afternoon, all of our testing should be finish before our schedule debut August 1st

Unless you have the MAF setup to be a draw-thru system, then the MAF will never see boost.

so what where the numbers on the base runs?? It's kinda become a, " hahahaha I have numbers and you cant see them'" game. If the kit is priced and ON THE MARKET, shouldnt the consumer get some kind of numbers.

Being that a 5 lb. boost is roughly 1/3 atmosphere, we can expect about an 80 h.p. increase over stock. Each lb. of boost is about a 16 h.p. increase.

Is that at the wheels or at the flywheel?

thanks charles R.
I was really curious. since you knew that, maybe you'll know this, how much intercooled boost do you think the rx-8 engine handle? Or is that more or an engine to engine, tuning based question?

wow how much would it be?

maybe a price quote?

RX8-Turbo system - $6250
TSI engine management system option - $1495
Ball-bearing turbo option - $600
304SS Cat deletion pipe - $399
thats whats on thier site

not that bad I guess if you want the power on tap.

I know I do, even though i can beat most gts from a roll and some from a stop. there is still however the z28 and the trans amm

Durability?
 

How durable is this kit going to be if I plan on roadracing my car every once in a while? Also how is the addition of a turbo going to affect my car's balance? If I know that these wont be a concern then I would go ahead and buy it!
