My 420A Race Car!!!!!

[XMasta19]

Oh I know...trust me, but I'm not the one to say anything. I've had questions about the build since page 1, but like I said it's not my place. He's the one happily dumping all the money and confidence into this shop. I wouldn't want him to question them bout somethin, then bam they get pissed off or what not...who knows what could happen ya know. I figure, just let the shop build it the way they think is all bad ass, and when they gotta go back to the drawing board later, they'll realize the mistakes or controversies then. It's kinda hard to raise questions when he really has no clue what's going on with the build minus what they tell him everything is for and what it costs.


EDIT: Like I said, if this car isn't deep in the 9's, I'll be disappointed. In no time, there should be more and more 420a's emerging into the world of fast. Homeboys in vegas are knockin on 10's with just a decent turbo setup, great tune, slicks, and nice driving. What's to say more of us can't be in that same situation with just a little money devoted in the right areas.

I am still confused about the whole co2 thing. I'm hesitant to even take a stab at it actually. From what it sounds like, the wastegate will be independant to the manifold charge because that manifold charge can be replaced by the co2. Rather then waiting for the gate to open or close, he can control it by charging it with co2. So the wastegate stays closed under high boost, and only opens on command. Same thing with low boost except he can add the charge for an earlier boost response.

Either that or he's creating some sort of vaccuum to pull the pressure into the wastegate quicker, so it thinks theres more pressure then there is?

I don't know.

Is this co2 going to be controlled manually or set via module/program supported in the boost controller/logger?

 

[knightrider4]

Plain and simple the Co2 is the setup he needs to run for the hp he is going to make. Most guys in sfwd use C02 to control boost. When you are talking about making large amounts of power wastegate springs dont like it and C02 is the best way to control boost at these high horsepower levels. Our shop car integra which will be running sfwd will be using a similar set up. Very nice set up i am contemplating going the same route for next season and building a 420a sfwd car. can't wait to see the finished product.

 

[Blitzeclips]

Sounds close. I don't think it will ADD horsepower. I think it will retain the horsepower lost through the wastegate.

 

[VelocitàPaola]

You're correct Blitz... it's not adding horsepower, just aiding his launch times.

What I don't understand is why you'd stick with gas actuation if you're so concerned with reaction times. Electronic actuation is available, more easily controllable, and it reacts at the speed of light.

you might have answered this already somewhere in the post, but what size injectors are you using. If you are using MsNs i want to see if i will need to run an external driver box to run 1000cc inj. I know that have one built in, but i dont know if it is strong enough to run 1000cc's. also how much are you going to weigh in at when all said and done do you think? sfwd you need to be 2400 or above. Which 40r and which size A/R are you using on the exhaust side for the divided housing?

 

[VelocitàPaola]

MSnS-E can drive 1000cc/min's just fine. It can pretty much drive anything you can throw at them... The "built in" part you're probably thinking of is the flyback circuit, and that's just to minimize inductive kickback from the injectors' coils. As for the power actually needed to open an injector... it doesn't necessarily increase with the size of the injector.

And he's not using MSnS-E as far as I know.

Another pic of the shield

I am sorry I must have missed the post to explain the purpose of the shield. So what purpose does it serve?

It is to prevent shrapnel from destroying nearby components when his clutch/flywheel or differential explodes.

Im running a Tech 3r standalone. w/ 1600cc injs... GT4067R .85 a/r

I am sorry I must have missed the post to explain the purpose of the shield. So what purpose does it serve?

it is a Scatter shield so when my clutch explodes at high rpm it dosent cut my foot off. The shield protects me from that.

Yes you are exactly right. and It is going to be programed

in all it coast money to do a build like this....can it be done for cheaper? PROBLEY! but this is what i want. YES i want the best of the best i do not want to cheap out anything. There isnt any problem with wanting to have the best of everything..right?

No one knocks the guy who dumps 40k into his supra of EVO. Personaly i do not think it is alot of money there is more expensive ways to do it. think about the guy who goes out and buys a brand new EVO then modifies it. How much do you think that guy spends in the long run.

BUT im not doing anything different than what has alredy been done with the Honda's

we will have to see in the long run if you guys could see the shop and the top notch cars that they put out you would have confidence in them also.

 

[Shadow98]

We're just worried about the car not meeting your expectations and it not making the power/speed you need/crave.

 

[VelocitàPaola]

No... but there is a problem with paying for something just for the sake of being unique when it doesn't perform as well as lower cost alternatives.

 

[knightrider4]

thanks velocitapaola for the MsNS info. The Gt4067 is not a ball bearing turbo. That is the smallest GT40 they make. It will still make around 700whp. I would have chose a 40r turbo i mean you are spending all this money going big but then you don't spend it on the turbo. We are actually trying out the 4094r with a custom housing from Australia to see how it will react on the honda. Honda's like big A/R's on a divided set up i am interested to see how it would react on the 420a. I also want to ask did you make a custom fuse box or just relocate the stock one?

it is a 67mm inducer and a 94mm exducer and it is a ball bearing turbo
but
it was discontinued because it was not coast effective for for Percision to continue to make it.
The fairly new one is the garrett GT4094r......but they are the same turbo....

we got ride of the fuse box and did a custon one...but it will be hidden along with the wire harness for a clener look

YES iam worried about that also but only time will tell but i have faith that everything will come out great. The shop has all the same expetations that i have also. I have known these guys for a quite some time now.

No... but there is a problem with paying for something just for the sake of being unique when it doesn't perform as well as lower cost alternatives.

but thats the problem with our car is that the all the lower coast alternatives imo are not that great. I know that everything will turn out good and perform.....just wait in like 17 days the car will be on the dyno...

exactly! For the price of an evo thats a stock 14 second car... he's building a car that will probably do 10's or so... If he has the money, I dont see whats the big deal? I know all of you would do the same if you had the cash to throw around, hell I would!

 

[95TalonOwner]

Let the man do what he wants to do!

 

[XMasta19]

Umm...my money would be better spent differently, and who's to say that his super custom race car would perform that much better. I'm not knockin him or nothing, I'm just saying that my perspective as well as others, is on a totally different tangent. So are you getting a precision turbo or a full garrett gt series? This thread is getting quite rediculous, and I think we should all just stop asking questions for now. The OP can continue adding updates and pics...but the rest should just sit out for "17 days" and the beast proves its might.

EDIT: my sarcasm is in no way saying that this car won't put out massive numbers, hell...supras can be dyno queens all day long, but just because you have 1000whp or so doesn't mean you're gonna get down the track any faster than the guy next door pushin less than 500 to the wheels. Good luck, and I can't wait for you to shut me up hehe

true true

it is a precision turbo which uses a garrett gt CHRA

 

[bmoha2]

I love that color white! Brilliant!

How? It's one of the first 420a drag cars. You don't think people have questions? I'm asking them. If you're skeptical thats fine but giving a personal opinion everytime doesn't contribute.

Please break 9's DSM ZERO. Please.

I honestly don't think why or where he spends his money is any of our business. If he wants to spend it one way then that's how he'll do it. No one is asking how any of you would spend it, so just let him do what he's been doing. It's easy to criticize from that side of the fence.


Nice to see I actually figured out what he was talking about with the co2.

ZERO- What type of wheels and tires are you running? Mickey Thompsons or..? Size(s)?

WOW, I'm suprised to hear a comment like that coming from you blitz, but I agree.

 

[VelocitàPaola]

This is a forum for sharing technical advice, not show-and-tell. He's got to expect opinions from everyone he shares his project with. Most of us can certainly admire his endeavor, but I think the shop is taking him for a ride with some of the stuff. For someone with such lofty goals, I'd just like to see his money going toward more necessary parts. Given my opinion, he can take it or leave it, but it's worth hearing.

Everyone here is welcome to share their opinions, just as long as they aren't forced on anyone.

 

[4UH8ERS]

ZERO, what do you plan on going with for your suspension set-up?

hoperfully you haven't explained that already and me forgotten it?
