Replied to my texts until Feb 12 , hasn’t heard from him since .

It’s been awhile since the last update but here it is , crank, rods and pistons are installed , new bearings toleranced and installed crankcase bolted up with Brian crowers arp case stud kit ( HIGHLY recommend over stock tty bolts ) all ring gaps were set , block honed , crankcase die ground for...

Crank , rods and custom comp. ratio cp Carrillo pistons were all from Brian crower and it was roughly 4500 usd including a arp crankcase bolt kit to get rid of the tty crank bolts .

Lol a couple my original build thread is linked ! I’ve put a lot of time and money into er for sure and this summer a pile more into the new improved version

Will be hard to judge from stock, was dealing with low boost on bottom end , found the issue as I tore the sled down so that’ll all be fixed when this stroker fires up so won’t have true comparison, this is on a big turbo drag sled so no day to day riding

Well kit has arrived … as stated in original post 4340 billet stroker crank , rods , pistons , arp case studs , hypersports ecu , stm 11.25 secondary , Kibblewhite inconel exhaust valves and stainless intake valves , stage 3 turbo camshafts and another pile of parts . Tore engine down , must...

I’ve used ADP rivets ultimate multi grip rivets with a pneumatic gun in the past and had 0 issues . I just changed the entire tunnel on my drag racing sled overall it’s not a horrible job at all .

Just wondering if anyone on here built a stroker 998 ? How is it for tuning and what does it run like ? My build list for this season and parts are already ordered are Brian Crower 4340 billet stroker crank (1071cc) , Brian Crower MOAR rods with larger piston pins , Cp Carrillo 8.5.1 pistons ...

Carillo doesn’t have anything on their rods . I assumed it was machined to a Yamaha 6 and it was so just use the numbers off your crank and 6 and should give you what bearings to use but ALWAYS check your clearances with plastigage

The extra kit is it a stage 3 or 4 ?

I know a few guys running their stage 3 in the mountains and they RIP and have been reliable . I have one of their stage 4 kits in a drag sidewinder and it it Crazy! Def recommend their sidewinder kits !

1071 cc with stock bore

Packard performance claims they have made 800 at the crank on their in house dyno YXZ sxs I’m unsure if it is the stock crank or not but on their website their stage 3 engine build mentions nothing of an aftermarket crank . Brian crower however does make a 4340 stroker kit crank as well as 4340...

Lol you might be right , but engine is fully built so hopefully it holds up

The mcx stage 3 kit is pretty good bang for your buck as well . 340 horse and seems to be bang on reliability wise . Kit will run 340 on stock header and even more with the new header. I did a full stage 4 kit last year and lemme tell ya it’s hauls the mail ! I planning to do a few more upgrades...

I’m running a 450hp big turbo mcx kit with 4 arm stm and stock secondary . Running 39/35 helix with black tan spring but I’m still working on getting it dialed in

I kept the internal wastegate and it’s a three port solenoid . The stock system isn’t really touched everything still plugs into stock locations to keep the ecu happy . There are 2 voltage converters that plug into the stock boost solenoid and the fuel rail pressure solenoid all the new stuff...

So last march I had the opportunity to purchase an insurance wrote off 2018 BTX. This would be my third sidewinder as I currently had a 2017 MTX162" and a 2019 SRX both are td multi map tuned and a LONG list of aftermarket parts on both. To properly premise this post and credit TD both sleds...

My 2017 did the same thing , changed out the anti stab wheels for a bigger size haven’t had the problem since . Order two of the part number in the picture they are direct replacement

Here is part number for Yamaha wheels that are larger and fit the stock anti stab shaft
