This is my new engine that i purchased from jason at rx7store, everything is all mocked up and ready to install. Im having a little setback with the tranny syncro, but hopefully everything will go in this week.







big thanks to rx7store and agp turbo

Mike

 

Finally someone buys something from Rx-7 store that i see..What stage is the engine I, II, III?
Congrats now have some fun with it

 

Looks good, update us after the install and break in.

 

looks sweet i am saposed to be giting back sometime this week from jason i got the stage III what stage is yours

 

its their stage II package, im shootin for about 15psi on pump, hopefully that will be enough for 400whp

 

I dd mine so i figured the race porting was a little much

 

Ohhh their stage II package ay...? Yea tell us how it is because when i got my car i was seriously thinking about rx7store. Did you order it off the internet or did u go to the shop to pick it up? Its in Maryland so i doubt that you would drive to pick it up but yah never know.

 

get that darn alternator pulley on there, and why do you have the airpump bracket thingy on the engine?

Is that a water temp fitting on the front of the water pump for an aftermarket gauge?

Is your FPR mounted on something or just sittin there?

I cant tell from the picture...

 

WOW! Looks great! Exactly what I'll go with if my engine decides to let go.

 

yeah i gotta get an impact to get the pully on the alt, and the airpump bracket is on their cause i havent gotten that far yet.

What thing are you talking about on the water pump? my car is a canada spec so maybe its something else?

The fpr is just sittin their for now

 

First (low boost) Dyno #s: RX-7Store Stage II, Stock Turbos (Non-sequential). See sig for mods.

Peak boost reading: 13.3 psi

382.2 RWHP @ 7000 rpm
303.8 Lb. Ft. @ 6250 rpm

Will be tuning for 15 psi in July. Dyno-graph and Time slips to be posted soon.

Saturday's (6/25) Time slip @ National Trail Raceway:

Poor Driver: Me (2nd time at track)
Temperature: 77 degrees
Peak boost reading: 0.82 bar (11.8931 psi)
Street tires on 18's (Toyo Proxes T1-S)

60' 2.114
300 5.583
1/8 8.376
MPH 89.90
1000 10.785
1/4 12.804
MPH 112.67

And I did it while spanking a 2003 Mustang Cobra (13.636@106.83)

 

nice

 

Wow, really similar to my times back when i was on stock sequential twins with all the bolts ons (368 rwhp).....ran a 12.7 @113 against a new cobra that ran a 13.6 @108....needless to say the cobra owner was like
"" and i was like" "

 

11.8931 psi??

lol, i know where that came from, but still...

significant figures people comon!

 

interesting...your trap seems low for your power. Perhaps your power, that was indicaed on the dyno, is wrong. I am willing to guess the latter especially since u said it was on a peak boost of 13 psi for crysake.

 

rich your old trap too. Are you guys lifting or somehting? i run 116 mph traps with opnly 340 rwhp, which seems right on target

 

Traction problems will limit your trap speed. I was out on street tires saturday running 19lbs of boost only trapped 121mph. I know my car is making more than 370HP at 19lbs

hey matt--

all of my runs were at a track near austin called little river/temple academy raceway. It's notorious for having slow et's b/c of a shitty track (not level/bad traction) and also b/c of the humidity (river parallels the track).

Having said that, not sure if my traps were affected by all this. I will tell ya that i have doubts that i ever dynoed at 368 on stock twins.....i was not there for the dyno and have heard stories about KDR's dyno being inaccurate since. I *will* say that 382 at 13 psi on stock twins ain't happening in my book. I made the supposed 368 at like 15 psi......

Rich

 

That's a purty engine, just courious do they come with 2mm or 3mm. I'm guessing 3mm.

 

my understanding is that trap speed is a good indication of power. My traps would hardly move despite my et flucuating .5 seconds and regardless of my 60 foot time.

 

see my reply to jason. Frankly i dont like dynos that much. I prefer to measure rwhp off of trap speeds. i made 340 rwhp and trap 116mph usually....they seem to match so i am comfortable in my dyno numbers.

 

Jason what psi was the 506rw again?
I trapped 121 with 379rw dyno corrected on a cold night so yes your traction is making you have a wimpy trap! well not that wimpy haha

 

Typically your trap speed doesnt change much based on your 60, but there are other factors that will change it.

Jason

 

nah i opted for the 2mm..

trap speed can be greatly effected by spinning the tires, and slow shifting.

also if you noticed he said he ran lower boost while at the track then he did on the dyno.

 

It was 19-20lbs of boost.
