hope this scale wasnt involved in building it i mean u may have a complete car like 4 years from now at this rate

 

According to rc engineering the injectors hes running flow enough fuel to satisfy his ~500whp estimate. However the fact that precision doesnt have a compressor map (if im wrong send it to me!!!) it makes it challenging to determine the actual amount of power the 6262 is capabale of putting down. According to the guestimations from other forum members and the formula supplied by Howard Coleman, the 6265... read it again.. the slightly bigger more rotary friendly 6265 is guestimated to flow at 68 pounds per min... the 6265 max's out at... 68 X 14.471 = 984CFM/ 1.92 = 512.5 max rotary rwhp (link for the thread with info and formula is here : https://www.rx7club.com/3rd-generation-specific-1993-2002-16/making-case-turbod-rotary-fd-turbo-options-simplified-869613/). Now the 6262 should be less than this... and keep in mind that until 20psi the 6262 is very similar to the gt35r with slightly faster spool. These billet turbos dont shine untill 22psi or more... and we have no idea of knowing what actual boost level the 6265 flowed 68 (gt35r flows 60 between 19-28psi for a whopping... 452whp). i would guess.. at 20 psi... the 6262 would flow ~465whp.

Now the fact that the OP was running AI as well changes things a bit, but for those of you looking to see what the street ported 13b with a 6262 would push... id say given the info on the board... around 465 ish..

BTW i would love to get a look at the sheet regardless of wether or not it blew up, since this is VERY similar to what i will be finishing up this summer.

 

HC's formula is good, but its a guideline for real people. really sharp tuners, like elliot at turblown, beat the 1.92 formula

 

Did his engine actually blow ? Or just crack a plate.. He told me his rear plate broke, and he ordered one of our stud kits.

 

so all that trouble just to pop the engine?

 

It's a rotary. That's what we LIVE for.

and I DO count this as a blown engine as it requires a rebuild. I WIN bishes.

 

cracked a plate .. car was a beast

 

 

Holy **** wow i forgot about this thread! Yeah there were Dyno issues.... with the dyno, not my car... Dave got it taken care of and literally last 3 runs it broke the rear plate.

lol Pvillknight... you kind-of win... I drove the car back onto the trailer...and if i had alot of oil, could have driven it home.... it made 468 with room to spare... just cracked the rear plate.

I put the thick late S5 rear plate I got from Japan2LA in, with the Turblown stud kit and a Pineapple oil pan just for kicks....

The car is a monster... it made the 468whp and 403 tq on 19psi. it does not get traction in a straight line till the top of 4th on 245's

Its great. I love it. 468 with room to spare. The low end (no boost under 3k) cruise needs some work with the transient throttle... but thats nothing an hour cant fix.

 

ooh... if we get down to the gritty and count the "because it loses a seal"... haha I'll give it to you though.

well because of the dyno issues that were going on... my car actaully got an extended break-in. as it was the guinea pig to diagnose the dyno malfunction.

 

goodluck with rebuild

 

oh all that stuff is already done... that was together the week I got the car back from Speed1.... I had to wait a month for the oil pan from Pineapple because they were out of stock... once the pan was here, I put it on, popped the motor back in and fired it right up. It might have cranked for 3 seconds before firing up and settling to an 850 idle.

I drove the car today actaully... I dont know who loves it more, me or my GF in the passenger seat. lol

 

lol had the same thing happen to me but not on a dyno but highway... Rear plate cracked 2 times on my motor... Looks like I need a tune...

 

the S5 plate shouldn't have cracked. ah well at any rate the stud kit should let you know if it was a weak rear iron or something else(will wind up eating a rotor/housing if it is lack of fuel or a tuning issue).

what was your injector duty cycle looking like?

i also still don't see why they set up your car with the bare minimum to get by with, that is asking for a short lived motor.

 

spark plug heat range was too hot, causing the concern and the cracked iron. I have since switched to NGK range 10's and all is well.

Max duty cycle is 81.02%... plus the meth injection... with a safe afr.
also at peak TQ, my duty is 48.76% ...and plenty fat....

I'm confident it'll last for a little bit.

 

Congratz! Sounds like you've been busy doing work. Glad to hear you've wrapped it up. Post some vids if you find the time.

 

Im absolutely sure beyond the shadow of a doubt that the 1.92 formula is a modest guideline but when speaking in guestimations i find its best to stay with generalities instead of pushing for the optimistic 100%. Good to see i wasnt to far off with my guess tho. Im looking forward to seeing what mine does when its all said and done. a few small differences between builds of course, but the numbers are hopefully going to be similar.

 

Yeah Dave's on point. I took care of the Transient throttle and the small lean out under cruising at around 3k.... it drives like a stock car... until you get into it.

If its anything "similar", you are going to love it.

 

^ Winner. Or maybe this guy:

I got second with 416. I blame the meth. Out of curiosity, what are your intake temps?
