I'm making 280rwhp on 11PSI. RX7 Series 5 13Bturbo street port. Standard turbo, standard injectors, 3inch exhaust, front mount inter-cooler, microtech LT8s ECU. Boost controller is a turbosmart E-boost Street.

Engine isnt running lean as AFR starts at 13.5 and with WOT go to 11.

I was really stocked with these results. Was tuned on the Gold Coast here in Queensland, Australia by Dyson Rotary.

that is pretty crazy for stock turbo and injectors. what kind of timing are you running?

 

No idea on timing. I blew my previous 13B turbo so I bought the long motor of a mate and put it my car. Did all the work on it myself then towed for the shop to tune it.

Well that beats the **** out of all the stock turbo records as far as I know. Stock fuel pump too? What was the injector duty cycle?

 

a guy I met at a meet claims to have run 303whp on the stocker.....it lasted 2 weeks lol.

I'm interested in the injectors used though, cause 550's struggle to keep up at lesser HP #'s.....

 

Well dysons do good stuff, if only the bloody turbo kit they sent me wasn't being such a pain

 

Nah fuel pump is just a walbro intank replacement. Injectors he said he was able to get them to open at 9ms, it think its close to 100%. Nice safe AFR though so i should be right.

I will however be keeping an eye on things.

 

I wouldn't trust the 550's to run at 100% for long.

 

I've got plenty of them, haha. If they fail it just means time to upgrade

 

or a blown engine


but yeah, 280 isn't bad at all... I made 270 on my BNR stage 2 hybrid @ 12 psi, but I'm still running the stock top mount... I need to get around to swapping that out

 

Nah the wideband will tell me when to shut things down. Yeah im not a fan of the top mount. sitting in where all the engine heat is..

 

On stock mount? You got ***** man.
I got 271whp on my stage2 @ 10.5PSI. But I have an FMIC and 8lbs Cusco flywheel though.

Spec.

 

under wot full boost if it goes lean its done and injectors fail quick when they do

 

true!

 

nice numbers

 

Get rid of those injectors asap! But nice job!!

 

Yeah nice numbers, but definitely upgrade your injectors.

 

Thanks. Yeah I'm changing them. I've got 2 1600's and 2 1000's to put in. Need money for big turbo though. Looking at going gt42 or t04z. I want around the 450-500 RWHP.

 

sounds like a gt35r would be good for you then. they work amazingly on a 13b, especially with a streetport.

 

Dyno Dynamics dynos are not known to read high, this is a credible claim
