Only 5psi-killed Srt4!!!
 

I was driving with my friend with a SRT-4 with some light mods boosting 15PSI he ran like a 14.1 1/4, we get to a red light at a 20MPH roll light turns green we both go in second, I pull ahead a little then he starts gaining, at the end of 2nd Im about a bumper up on him by the end of 3rd I can barly see his front bumper when I looked over. I thought I was boosting 10PSI BUUTT when I was driving home I noticed it boosts to 10 quick then drops to 5 in first the same thing drops to about 7 in 3rd, so I pull over turn up the MBC now its boosting 10 and holding!!! I WANNA RACE HIM AGAIN!!!! but I was excited befor but now Im Its just GREAT!!!

I know this isnt the tech section but does anyone know why it does this???
My mods are
Ported engine
stock turbo(stock wastegate)about to go
3" turbo back exhaust
greddy 720 secondarys
FD fuel pump
Rtek 1.7 ECU

Ah SRt-4s are pretty nice considering they are neons. My friend got walked on by one car leghth by one. He had a n/a 300zx and the guy was boosting over stock. Needless to say the 300zx owner is in the process of aquiring a turboed engine.

They sound pretty sweet also it SCREEMS and he has a mopar BOV sounds pretty sweet.

YEah the one my friend raced had a blow off valve too. Really sweet sounding.

You better race him again before he gets more mods..

Good Kill!

An N/A 300 ZX only lost by one car? From what 10 to 20? 300 ZX's are balls out slow, no match for an SRT.

BOV, you are probably talking abou tthe Mopar spacers they use that make so much damn noise. Rev it to 2 grand and it blows off.

yep thats it!

Mopar Party favor type Rice valve Noise maker wanna be a real BOV (MPFHBTRVNMWBARB) :

The MPFHBTRVNMWBARB does not do anything other than make noise. It does not relieve the pressure from the turbo, the actual surge valve on top of it does that. It does not accomidate more boost, it does nothing. It just takes the already expelled air and vents it instead of putting it back into the inlet of the turbo. There is only one thing the MPFHBTRVNMWBARB does which probly helps in theory but you really can't feel the difference. It prevents air from entering the turbo at 90 degrees to the air coming from the intake. ANd thats about all it does. Well i take that back, the MPFHBTRVNMWBARB also has a nice OMG bling bling affect to a certain degree.
Read up boys for those of you who know SRT owners or have an SRT with the mopar Rice valve.

Nice kill. Call me stupid, but don't ALL turbo'd cars have BOV's?

As far as I know every turbo car has a BOV or something like it. Some use a redirecting valve or something so it doesn't go to atmosphere. When people usually say the car has a BOV it's cause they have a non stock one which makes a lot of noise. Most stock BOV's are pretty quiet.

He only lost at 3rd gear also (it seems srts have a mean 3rd gear). I don't know what N/A 300zx you are thinking of but you know the one nissan made with the vg30 engine. After all a Srt maybe nice but is just a f***ing neon. where as the 300zx and rx-7 are pure bread sports cars. :bigthumb:

Interesting so that noisey "mopar rice valve." does nothing.

and every turbo doesn't have a BOV a blow off vavle blows the air into the atmosphere the redirecting valve just puts it back into the turbo. Whether or not it improves performance...

bred.... not bread cause im not eating a rx7 or z sandwhich, yes n/a z's are REALLY slow not even a match for a srt 4 yeah its a neon but its a really fucking fast neon

^ word...

Well I am telling you what i saw an srt-4 was racing a 300zx both close to stock. they were even until 3rd gear when the srt-4 pulled away and it was over... You can say what you want but i saw what i saw buddy.

SRT-4 driver sucked then. MY friends H22 coupe is dead even with his friends 300zx TT(stock). He loses to my friends SRT-4 with bolt-ons. An N/A 300ZX makes about 170 whp. My moms Sentra could probably hang. :rlaugh:

its could all so be possible that the srt-4 was not in the greatest of shapes

It kills me to say it, but even though they are "Neons", SRT4's are no joke.
And you said that the SRT4 he had runs 14.1? Dont they run 14.2 stock?
Sounds like this guy sucks at driving...

quite possible...

dude the guy was a lame ass driver , they run low 14's to high 13's with a REALLY good driver, but with mods that cat should be able to hit 14 flat easy which would tear a old beat up na 300 a new asshole....

my friend got SmOkEd out of his mind by a srt-4 they were going about 40mph, my friend in a 240 with sr was in 2nd i think....they took off and the srt-4 was more then a car length if not 2 ahead before my friend even got to 3rd...........we found out where the guy works and checked his car out while it was parked so we didnt talk to him but it seems to be modified quite a bit......from what we could see it was straight 3" pipe off the turbo all the back...pretty big fmic....and carbon fiber hood...rest we couldnt tell but he was fast

after all that my friend told me it dosnt matter that he beat me.... at the end of the day he is still driving a neon and laughed

either way out..a neon is a neon
but a srt4 is just a quick version :)

update!!! my friend with the SRT4 put bigger injectors and a ECU in and is running 20PSI boost rather then 15, well last night I raced him again it was kinda cool and my car was boosting 12 PSI in second and third we raced at a light from a start 1st and 2nd I pulled on him pretty good and had a car on him then in thrid he started to catch up a lil we stoped at about 90 and I has still almost a car ahead of him!

anybody who can drive in an srt can run low 13's, i know a guy with just an exhaust and waste gate in his and he runs high 12's. those cars are nuts. but retarded because they are fr.

Yeah, low 13's high 12's are pretty common with those SRT's....if you're going to race them on the street, try not to go from a roll, because their FWD doesn't give them traction for the takeoff. ;)

These are 1/4 mile times for stock srt-4 and 300zx na.

1990 Nissan 300ZX 7.1 15.5
2003 Dodge SRT-4 5.6 14.1

Even if the Srt-4 was a sorry driver, the power difference is too great. It would have to be a 300zx tt to be a match. A Srt-4 was neck and neck with my fc turbo at about 100mph from a 40mph roll. A 300zx na was a good match for my 91 na rx-7 back then. my old 95 civic hatchback si with intake, headers, exhaust, cam gear, killed a 300zx. You obviously follow what people say to much, have respect for cars man. Its like I know the 7 is the shit, but it has its ups and downs like every other car. And you gotta be realistic in comparisons.

anything is possible on the street.

My close friend just bought a red 05 srt4 3 weeks ago from friday, they dont even make them anymore and he diddnt want a used one... so he went to maine to get one of the VERY last new ones.

Well with about a week or so of stick driving under his belt we roll up to a light last friday and next to us rolls a red integra with an exhaust. The kid looks over and the drivers make eye contact. In the integra its a guy and 2 girls in the srt its my friend, my girlfriend, and I.
Green light and they roll out normally then the integra guns it, my friend guns it in 2nd, (when he "gets on it" he dosent mash the gas... you cant ease on the accelerator and be a threat...) Anyways hes boosting at speeds like hes got twin t88s... and the integra walks him by 3-4 cars. Pretty emarassing.

At the next light. We roll up to them again, the girls are laughing at us and the guy probably just thought he was the king of the world. After loosing, my friend then shouts from his window, your cars a peice of shit, mine is faster, blah blah "you had to beat the hell out of it to race me" and the kid is calm im surprised he wasnt spitting honda lover type shit and all he says in a cool way was, "well you diddnt pass me". LOL at that point we all were laughing at SRT4 boy. I BEG for him to let me drive against him, but he refused, ive driven his car before, im sure i can handle turbo cars...

Green light he goes normally so dose integra, then all of a sudden im inside an srt4 that is puling a ricer flyby on some harmless guy. To beat this kid all he had to do was put in 2nd and floor it, easy 5 car kill. +1 to integra driver, he probably had a threesome that night.

+1 to you, i think that goes to all people who dont know what they are talking about. Have you seen DSM guys? :icon_no2:

Point is, not everyone can drive what they own.

FWD cars have awful time hooking up and you say this SRT-4 is lightly moded right? To me that explains a time of 14.1. Do you know the trap speed by any chance?

I'm thinking that whatever made you boost below 10 psi happened AFTER you raced your friend. A mildly modded FD @ 10 psi should pull on a lightly modded SRT-4 just as you described.

Our cars really need the boost. I dynoed my car at 6 psi before and I had a whopping 189 RWHP (IIRC). Now at 12 psi (and some more mods catback, CAI, and IC) I'm somewhere in the vicinity of 300 RWHP (enough to give stock C6's a run for their money).

Trust me I HATE SRT-4's cuz of their owners, but that stupid looking car is fast.

Stock a NA Z runs around 15.1 with some going as low as 14.7 all stock. A stock TT should run around 13.8. A H22 should have a hard time with the NA, the TT has something seriously wrong with it...

I completely disagree after riding in one. It was wet, so there was tons of wheel hop, but...they are no joke, even stock.

SRT-4 ride quality is crap... i rode in my friends for 20-30 minites and my ass started hurting like crazy because it was so rough (stop thinking nasty guys).

Where Im at theres about 6-7 Srt's out every Friday night of all different speeds.. Im basically stock non seq- turbos running at 12 psi with full exhaust intakes nothing major... I can easily hang with the Stage 2's... Stage 3's arent much faster from a roll but at the track I can run the same times as them but I have no tires at all maybe 30% tread if that...

On the topic of SRT-4s...I ran into one tonight and pulled it! He pulled out from a gas station behind me. His car looked clean, a body kit but a subtle one. I could hear his BOV over the sound of the wind and my car, I had the sunroof open and the windows down. The BOV sounded like metal dragging on concrete though :ugh2:. Anyways we come up to this straight road and, if I ever speed in my Rx, its on THIS road...I know it very well.

As we came around the corner, he started pulling up close behind me like he was going to try and pass me..I downshifted to second and put down the pedal! 2nd was gone fast and I did a perfect 3rd shift, he was slowly falling back but nowhere near as fast as I thought he would! I topped out 3rd and started to slow, I had him by 2-3 carlengths. I was pretty impressed how well he kept up!

Heres my cars current setup, the car was @ 90C when I hit the gas-

Downpipe
RB Duals
Apexi Intakes
PFC + Commander

Everything else is stock, and the PFC is untuned and using the base map right now....Im waiting to find a nice intercooler, then I will be adding that then a tune...and hopefully will be stopping there since this is my DD.

Srt4's are not that bad it's the owners that make it look like a super car go on the Srt forums and you will see how many stupid people slap a big turbo on a stock engine and blow it with minor mods you can see a nice gain in power but the car with stock suspension is crap on the turns overall is a good car but the sound it makes could be better lol.
