imprezedrs on here is a local guy running a turbo gxl... 6 port with s5 tii manifolds, turbo and s4 tii ecu. safc 460s and 720s, fmic, TID, 3" DP and CB no cats.... he did like 204 on like 10 psi if i remember right. but that dyno was back when he had the n/a ecu... hell he had a very different setup when he dynoed.

but it has nothing left. aluminum dash, sunroof... no anything... its a easy bake oven.... it suprised the hell out of me when he got me freeway when i was on low boost.
he makes boost at like 2.3k
he needs to dyno again... hell he might run a high 12 when it gets the bugs worked out.

 

Mine did, at 12-14 PSI on not enough fuel. I have not posted any timeslips because I simply can't find them in the enormous box of slips that I have. I don't post about it because a bunch of people that have no 6 port turbo experience start arguments...But you'll find similar experiences with most of us that have run any kind of boost on the 6 port block.

 

This might actually turn into a good thread with good info!(no more v8's!) lol


more more

 

nice!! now since im runnin 720's i SHOULD be safe with the fuel but im pretty concerned about that much boost!!! did you have full interior??? should i be safe for just track days????now my motor has like 46,000 origonal miles on it also....

 

Just because you haven't been removed from the box you think in, doesn't mean that I'm wrong.

1500lbs is silly. Research and get out of your box, too.

Thats still in the box.

Correct me if I'm wrong, (REALLY). But he didn't ask for a 12 sec Naturally Aspriated RX-7. He askes for a 12 second RX-7.


tsk tsk

Maybe I didn't make myself clear. That could be my fault. The thread starter did not state wheter or not the motor, powering his 12 second FC, would be N/A. I'm sure a 12 second N/A FC is possible, but I'm not advocating ripping out the entire car to some silly weight like 1500lbs.

A properly modified NON-turbo, stock port 13B can push a 2nd gen into 12's. I shouldnt have to explain how. If you figured it out, that makes you one point smarter.

What do I think it would take to run low 12's in an FC???
300RWHP in a 2800 FC.
How you make the HP is your own debate. I'll use nitrous.

 

i made 222whp@10psi in my 91 NA>T2 (it had 9.0 rotors)


and he has a serious problem (or he's about to) if he's running 10psi from a s5 turbo on a 9.7:1 6port engine with 460cc NA injectors...

 

yea he figured it out... he has 550 and 720s my old tii ecu, fpr, and a safc... he does have a plx m-300... everyone in my group does

 

According to the ET calculator URL from the first page at 2700lbs with 26" tyres and 3.11 final it takes 287 hp to get to 11.87 .. in which case a simple P port NA with 22" primaries and min of dual 48mm webbers will do the trick.. if it's wheel hp then bump the 48's to 55's and your over 300hp easy.. ( dynos for the 48's to prove it.. )

peronally I think 287hp on a 2700lb car is a bit too favorable for sub 12.5 never mind 11's

 

AHAA!!!

Well bigD...I'm going to give on this one, you are absolutely correct. I wasn't even considering NOS, have never used it and honestly I know very little about them, I don't like it. Sicne I started I saw too many engines on NOS blow up. I know new systems are reliable but I feel it kinda like cheating...that's just me though.
