Just received this email from my Dad. This is his take on the recent Tri State dyno day with Steve tuning. All the tuning with my R1 happened on the drive back from PA to NJ. This was with new 10.5s Leading and 11s Trailing, and at 1.10-1.14 boost (~16psi).

Check it out:
======================================
Me, Kan, Ryan and his friend Bryan drove to So. Jersey and then onto the dyno facility in bum-**** Pennsylvania for Thursdays tuning session... Steve was only able to tune 4 cars because of some problems.

We left the house in Morristown @ 0930. Jayspec7 met us in Morristown @ 1000; he drove down from Rockland Co. New York... Nice Guy.

We then caravaned down to exit 4 off the Jersey Turnpike... Met up with "Keith's" folks.... and didn't get to the dyno facility till 1500, hitting traffic jams along the way... It was hot with reported air temps (according to the PFC commander) of 70C....

The good news is that while your car wasn't put on the dyno.... we spent the entire drive home making pull after pull in both 3rd and 4th gear. Steve cleared up ALL the funky engine running issues from idle up through 8000RPM. Result.... Your car is fast as hell..... This thing is a BEAST!! Steve thinks that it's as powerful as any single turbo he's been in and asked me my opinion of it's felt horse power.... Anecdotally, I say you're putting down somewhere in the region of 425 to 450HP... Steve agreed that that was probably not too far off. Now, We'll see.

Saturday is another dyno session... I plan to have fresh oil in the car and be ready for Saturday's pulls.

How I didn't get busted by the cops on the way home is beyond me... And, there was more than one instance of a cop pacing me and watching the whole thing.... At one point, Ryan, who was riding trail in the Subaru, said that he noticed a pace car on his right rear quarter, so he slowed up to the speed limit.... The cop paced him for a while and then sped up to catch up with me.... Ryan was frantically trying to call my cell but of course couldn't get through because I was a just a little preoccupied.... Going 140MPH will do that!... However, maybe because I was doing the pull and immediately slowing down to a normal speed limit, and there where no other cars in the area, the cop left me alone.... So, all totalled, Steve spent the better of 3 solid hours tweaking this and that to get you car solidly performing throughout the entire RPM range...

Well gotta go, will write more later.... And yes.... I think you car is now faster than my old L-88 Corvette... !!!

Love,

DAD

PS: You owe me big time junior!!
=======================================

 

awww...what a sweet dad.

 

My GOD, I wish I had this kind of relationship with my Pa! He's a good man, but risking 140 mph with Jersey cops???

That's love man. *sniffle*

 

Sounds good. Great father.

 

jeez, can i be your brother. . . my dad has been in my car twice. . . he wont mess with it. i think hes afraid hell break something. dont ask me why. once i get this thing tuned im gonna take him out in it and show him what the deal is. hahaha.

paul

 

i have hung and spoken with your pops quite abit in the past 3 months....great guy.

Dyno sheet should look impressive.

ps: 70 degree intake temps is nothing man...i saw 86 degree intake temps coming back from etown last week sitting in NYC traffic...made me nervous.

 

what twins from BNR are you runing? Stage 1?2?3?

 

3

 

damn. What's the spool characteristics like on that? Would they be good for auto-x or are they a little too laggy for that?

 

yes richard, my golden child, i too am thrilled your beast runs so fast. i just wonder which is more risky, being in baghdad as a us soldier, or, being behind the wheel of your red racer. also, don't forget that i help you out alot too, managing your "things" while you are away and putting up with 2, yes 2, rx 7 s in the garage while my subaru outback stays outside. but, as i have said before, i'd only do it for you, richard, you deserve it, since you are the greatest son any mom could have.

 

where was the punch line?

 

sounds good - looking foward to the dyno results - should be another dyno sheet to prove the BNRs kick ***. I'd imagine they'd be ok for autocrossing since they spool almost as fast as the seq setup - I have my BNRs setup seq which would rock autocrossing but you'll lose some of the midrange pop that non-seq offers.

 

Dynamic seals in the hizzouse

 

Heh. That's a good question . I haven't driven her in so long. 10 psi by about 3000 rpms and 16 psi by maybe 3800? it's perfectly streetable, and pulls harder than my stock sequentials did between 3000 and 4000.

My dad or Steve could prolly answer the question better after today. I know that it's perfectly streetable---at least 3 fellow FD owners that have ridden with me thought she was seq until I pointed to all th space under the UIM

When building my car, I've been looking towards a streetable potential daily driver that will spend alot of time on the road course with occasional blasts down the drag strip. I'm thinking of auto-xing with damonb next season, but have yet to try my hand at it.

If you want similar spool characteristics, you'll need a similar setup to mine. Minimal backpressure in a downpipe, midpipe, and PFS Catback with no muffling left. Also, K&N filters (with Gotham hardpipes soon to be installed), M2 large SMIC, Kan very aggressive ported motor, flapper door cut out of the exhaust mani.

hope this helps,
Rich

 

Um, I didn't think that Moms were allowed on the forum! Mods??

 

How many kids named Richard does your mom have? "Hi, I'm Daryl. This is my brother Rich and this is my other brother Rich".

 

What did you end up dynoing at, Barry?

 

Oh, you're reeeeeally funny. Ha. Ha. Ha. The next time need a flatbed, you're on your own pal

 

hmmm sounds like the BNR stage 3s might be the way to go. How much boost can they blow?

 

Hmmm. Going off memory, I think Brian told me they were in their efficiency range at right around 17 psi. I think they can safely run 20, but not positive. Right now b/c of the limits of the stock 2 bar map sensor my pfc commander only reads up to 1.15 or 16.4 psi......

 

Sounds pretty impressive. Hopefully we'll gave our Bi-State Customs Upgraded twins dynoed shortly.

Sounds like you got a pretty cool papi

 

My last dyno up at KDR was 380 rwhp at 15 psi. I was hoping for more but I still have my HF cat - I know there's more in these turbos at 17 psi - they kick *** running sequential but don't know about running more boost in seq mode. I would if I had Kan tuning - I don't think I've seen or heard of a dyno of 400 rwhp running sequential - I know it can be done with these turbos even though they're not dynamic seals. Next time Steve Kan's in the Tri-State area I'll definitely have him tune my car if I still have it.

 

The old L-88's made ~360 rwhp with the stock manifolds and ran mid 12's with the headers that came in the trunk.
I read an article from the mid 90's that tested one on a drag track with a pro driver, slicks and a 4:56 rear end. It ran mid 12's @ 112-114.(It also beat the 427 side oiler cobra which ran high 12's on street tires.)

 

Hey Rich,
When is Gotham going to get its own dyno?

 

My Dad's L-88 was pretty heavily modified. I know he was definitely in the 11s at the drag strip. He's always said over the years "yeah, your 7 handles like a dream and is pretty fast, but it's no match for my old vette in a straight line." Now he's singing a different tune . I'll ask him to post in this thread about it.
